Updating Superset

This file documents any backwards-incompatible changes in Superset and assists people when migrating to a new version.

Next

  • 13772: Row level security (RLS) is now enabled by default. To activate the feature, please run superset init to expose the RLS menus to Admin users.

Breaking Changes

Potential Downtime

Deprecations

  • 13440: Dashboard/Charts reports and old Alerts is deprecated. The following config keys are deprecated:
    • ENABLE_ALERTS
    • SCHEDULED_EMAIL_DEBUG_MODE
    • EMAIL_REPORTS_CRON_RESOLUTION
    • EMAIL_ASYNC_TIME_LIMIT_SEC
    • EMAIL_REPORT_BCC_ADDRESS
    • EMAIL_REPORTS_USER

Other

1.1.0

Breaking Changes

  • This is the first release since we adopted semantic versioning (SIP-57). There are no breaking changes in 1.1.0 since this is a minor release.

Potential Downtime

  • 13111 has a database migration that replaces directed_force charts with newer graph_chart charts based on Apache ECharts.
  • 13216 adds a UUID column to models that are missing it. The original migration script that added the column would incorrectly complete when the column couldn't be added, resulting in a broken schema. The script is optimized for MySQL and Postgres, so depending on the database and the number of objects this migration might take considerable time.
  • 12960 populates the granularity parameter in existing charts. Depending on the number of charts without a granularity or granularity_sqla param this might take considerable time.
  • 13052 updates the label in existing pie charts, setting label_type from pie_label_type. Depending on the number of pie charts this might take considerable time.
  • 12680 creates a new table, dashboard_roles, for role based dashboard level access.
  • 12552 updates charts that have the time range defined using "until" and "since". Depending on the number of charts this might take considerable time.

Deprecations

  • 12552 removes the use of unclear time offsets, eg, "30 days". An error message is displayed if the user doesn't specify "ago" or "later", instructing the user of the correct format.
  • 12627 deprecates the legacy alerts module.

Other

  • shillelagh is now the recommended module to connect Superset to Google Spreadsheets since it's more robust and has extensive test coverage. You should uninstall the gsheetsdb module and install the shillelagh module in its place. Shillelagh is a drop-in replacement, so no modifications are needed to be done on existing queries, datasets, or charts.

1.0.0

Breaking Changes

  • 11509: Dataset metadata updates check user ownership, only owners or an Admin are allowed.

  • Security simplification (SIP-19), the following permission domains were simplified:

    • 12072: Query with can_read, can_write
    • 12036: Database with can_read, can_write.
    • 12012: Dashboard with can_read, can_write.
    • 12061: Log with can_read, can_write.
    • 12000: Dataset with can_read, can_write.
    • 12014: Annotation with can_read, can_write.
    • 11981: Chart with can_read, can_write.
    • 11853: ReportSchedule with can_read, can_write.
    • 11856: CssTemplate with can_read, can_write.
    • 11764: SavedQuery with can_read, can_write. Old permissions will be automatically migrated to these new permissions and applied to all existing security Roles.

  • 11499: Breaking change: STORE_CACHE_KEYS_IN_METADATA_DB config flag added (default=False) to write CacheKey records to the metadata DB. CacheKey recording was enabled by default previously.

  • 11704 Breaking change: Jinja templating for SQL queries has been updated, removing default modules such as datetime and random and enforcing static template values. To restore or extend functionality, use JINJA_CONTEXT_ADDONS and CUSTOM_TEMPLATE_PROCESSORS in superset_config.py.

  • 11509: Config value TABLE_NAMES_CACHE_CONFIG has been renamed to DATA_CACHE_CONFIG, which will now also hold query results cache from connected datasources (previously held in CACHE_CONFIG), in addition to the table names. If you will set DATA_CACHE_CONFIG to a new cache backend different than your previous CACHE_CONFIG, plan for additional cache warmup to avoid degrading charting performance for the end users.

  • 11575 The Row Level Security (RLS) config flag has been moved to a feature flag. To migrate, add ROW_LEVEL_SECURITY: True to the FEATURE_FLAGS dict in superset_config.py.

  • 11259: config flag ENABLE_REACT_CRUD_VIEWS has been set to True by default, set to False if you prefer to the vintage look and feel. However, we may discontine support on the vintage list view in the future.

  • 11244: The REDUCE_DASHBOARD_BOOTSTRAP_PAYLOAD feature flag has been removed after being set to True for multiple months.

  • 11172: Turning off language selectors by default as i18n is incomplete in most languages and requires more work. You can easily turn on the languages you want to expose in your environment in superset_config.py

  • 11172: Breaking change: SQL templating is turned off by default. To turn it on set ENABLE_TEMPLATE_PROCESSING to True on FEATURE_FLAGS

Potential Downtime

  • 11920: Undos the DB migration from 11714 to prevent adding new columns to the logs table. Deploying a sha between these two PRs may result in locking your DB.

  • 11714: Logs significantly more analytics events (roughly double?), and when using DBEventLogger (default) could result in stressing the metadata database more.

  • 11098: includes a database migration that adds a uuid column to most models, and updates Dashboard.position_json to include chart UUIDs. Depending on number of objects, the migration may take up to 5 minutes, requiring planning for downtime.

Deprecations

  • 11155: The FAB_UPDATE_PERMS config parameter is no longer required as the Superset application correctly informs FAB under which context permissions should be updated.

0.38.0

  • 10887: Breaking change: The custom cache backend changed in order to support the Flask-Caching factory method approach and thus must be registered as a custom type. See here for specifics.

  • 10674: Breaking change: PUBLIC_ROLE_LIKE_GAMMA was removed is favour of the new PUBLIC_ROLE_LIKE so it can be set to whatever role you want.

  • 10590: Breaking change: this PR will convert iframe chart into dashboard markdown component, and remove all iframe, separator, and markup slices (and support) from Superset. If you have important data in those slices, please backup manually.

  • 10562: EMAIL_REPORTS_WEBDRIVER is deprecated use WEBDRIVER_TYPE instead.

  • 10567: Default WEBDRIVER_OPTION_ARGS are Chrome-specific. If you're using FF, should be --headless only

  • 10241: change on Alpha role, users started to have access to "Annotation Layers", "Css Templates" and "Import Dashboards".

  • 10324: Facebook Prophet has been introduced as an optional dependency to add support for timeseries forecasting in the chart data API. To enable this feature, install Superset with the optional dependency prophet or directly pip install fbprophet.

  • 10320: References to blacklst/whitelist language have been replaced with more appropriate alternatives. All configs refencing containing WHITE/BLACK have been replaced with ALLOW/DENY. Affected config variables that need to be updated: TIME_GRAIN_BLACKLIST, VIZ_TYPE_BLACKLIST, DRUID_DATA_SOURCE_BLACKLIST.

0.37.1

  • 10794: Breaking change: uuid python package is not supported on Jinja2 anymore, only uuid functions are exposed eg: uuid1, uuid3, uuid4, uuid5.

0.37.0

  • 9964: Breaking change on Flask-AppBuilder 3. If you're using OAuth, find out what needs to be changed here.

  • 10233: a change which deprecates the ENABLE_FLASK_COMPRESS config option in favor of the Flask-Compress COMPRESS_REGISTER config option which serves the same purpose.

  • 10222: a change which changes how payloads are cached. Previous cached objects cannot be decoded and thus will be reloaded from source.

  • 10130: a change which deprecates the dbs.perm column in favor of SQLAlchemy hybird attributes.

  • 10034: a change which deprecates the public security manager assert_datasource_permission, assert_query_context_permission, assert_viz_permission, and rejected_tables methods with the raise_for_access method which also handles assertion logic for SQL tables.

  • 10031: a change which renames the following public security manager methods: can_access_datasource to can_access_table, all_datasource_access to can_access_all_datasources, all_database_access to can_access_all_databases, database_access to can_access_database, schema_access to can_access_schema, and datasource_access to can_access_datasource. Regrettably it is not viable to provide aliases for the deprecated methods as this would result in a name clash. Finally the can_access_table (previously can_access_database) method signature has changed, i.e., the optional schema argument no longer exists.

  • 10030: a change which renames the public security manager schemas_accessible_by_user method to get_schemas_accessible_by_user.

  • 9786: with the upgrade of werkzeug from version 0.16.0 to 1.0.1, the werkzeug.contrib.cache module has been moved to a standalone package cachelib. For example, to import the RedisCache class, please use the following import: from cachelib.redis import RedisCache.

  • 9794: introduces create view as functionality in the sqllab. This change will require the query table migration and potential service downtime as that table has quite some traffic.

  • 9572: a change which by default means that the Jinja current_user_id, current_username, and url_param context calls no longer need to be wrapped via cache_key_wrapper in order to be included in the cache key. The cache_key_wrapper function should only be required for Jinja add-ons.

0.36.0

  • 8867: a change which adds the tmp_schema_name column to the query table which requires locking the table. Given the query table is heavily used performance may be degraded during the migration. Scheduled downtime may be advised.

  • 9238: the config option TIME_GRAIN_FUNCTIONS has been renamed to TIME_GRAIN_EXPRESSIONS to better reflect the content of the dictionary.

  • 9218: SQLite connections have been disabled by default for analytics databases. You can optionally enable SQLite by setting PREVENT_UNSAFE_DB_CONNECTIONS to False. It is not recommended to change this setting, as arbitrary SQLite connections can lead to security vulnerabilities.

  • 9133: Security list of permissions and list views has been disable by default. You can optionally enable them back again by setting the following config keys: FAB_ADD_SECURITY_PERMISSION_VIEW, FAB_ADD_SECURITY_VIEW_MENU_VIEW, FAB_ADD_SECURITY_PERMISSION_VIEWS_VIEW to True.

  • 9173: Changes the encoding of the query source from an int to an enum.

  • 9120: Changes the default behavior of ad-hoc sharing of queries in SQLLab to one that links to the saved query rather than one that copies the query data into the KVStore model and links to the record there. This is a security-related change that makes SQLLab query sharing respect the existing role-based access controls. Should you wish to retain the existing behavior, set two feature flags: "KV_STORE": True will re-enable the /kv/ and /kv/store/ endpoints, and "SHARE_QUERIES_VIA_KV_STORE": True will tell the front-end to utilize them for query sharing.

  • 9109: Expire filter_immune_slices and filter_immune_filter_fields to favor dashboard scoped filter metadata filter_scopes.

  • 9046: Replaces can_only_access_owned_queries by all_query_access favoring a white list approach. Since a new permission is introduced use superset init to create and associate it by default to the Admin role. Note that, by default, all non Admin users will not be able to access queries they do not own.

  • 8901: The datasource's update timestamp has been added to the query object's cache key to ensure updates to datasources are always reflected in associated query results. As a consequence all previously cached results will be invalidated when updating to the next version.

  • 8699: A row_level_security_filters table has been added, which is many-to-many with tables and ab_roles. The applicable filters are added to the sqla query, and the RLS ids are added to the query cache keys. If RLS is enabled in config.py (ENABLE_ROW_LEVEL_SECURITY = True; by default, it is disabled), they can be accessed through the Security menu, or when editting a table.

  • 8732: Swagger user interface is now enabled by default. A new permission show on SwaggerView is created by superset init and given to the Admin Role. To disable the UI, set FAB_API_SWAGGER_UI = False on config.

  • 8721: When using the cache warmup Celery task you should now specify the SUPERSET_WEBSERVER_PROTOCOL variable in your configuration (probably either "http" or "https"). This defaults to "http".

  • 8512: DRUID_IS_ACTIVE now defaults to False. To enable Druid-API-based functionality, override the DRUID_IS_ACTIVE configuration variable by setting it to True for your deployment.

  • 8450: The time range picker now uses UTC for the tooltips and default placeholder timestamps (sans timezone).

  • 8418: FLASK_APP / Worker App have changed. FLASK_APP should be updated to superset.app:create_app() and Celery Workers should be started with --app=superset.tasks.celery_app:app

  • 9017: SIP_15_ENABLED now defaults to True which ensures that for all new SQL charts the time filter will behave like [start, end). Existing deployments should either disable this feature to keep the status quo or inform their users of this change prior to enabling the flag. The SIP_15_GRACE_PERIOD_END option provides a mechanism for specifying how long chart owners have to migrate their charts (the default is indefinite).

0.35.0

  • 8370: Deprecates the HTTP_HEADERS variable in favor of DEFAULT_HTTP_HEADERS and OVERRIDE_HTTP_HEADERS. To retain the same behavior you should use OVERRIDE_HTTP_HEADERS instead of HTTP_HEADERS. HTTP_HEADERS will still work but may be removed in a future update.

  • We're deprecating the concept of "restricted metric", this feature was not fully working anyhow.

  • 8117: If you are using ENABLE_PROXY_FIX = True, review the newly-introducted variable, PROXY_FIX_CONFIG, which changes the proxy behavior in accordance with Werkzeug

  • 8069: introduces MessagePack and PyArrow for async query results backend serialization. To disable set RESULTS_BACKEND_USE_MSGPACK = False in your configuration.

  • 8371: makes tables.table_name, dbs.database_name, datasources.cluster_name, and clusters.cluster_name non-nullable. Depending on the integrity of the data, manual intervention may be required.

0.34.0

  • 7848: If you are running redis with celery, celery bump to 4.3.0 requires redis-py upgrade to 3.2.0 or later.

  • 7667: a change to make all Unix timestamp (which by definition are in UTC) comparisons refer to a timestamp in UTC as opposed to local time.

  • 7653: a change which deprecates the table_columns.database_expression column. Expressions should be handled by the DB engine spec conversion, Python date format, or custom column expression/type.

  • The repo no longer contains translation binaries (.mo) files. If you want translations in your build, you now have to run the command babel-compile --target superset/translations as part of your builds

  • 5451: a change which adds missing non-nullable fields to the datasources table. Depending on the integrity of the data, manual intervention may be required.

  • 5452: a change which adds missing non-nullable fields and uniqueness constraints (which may be case insensitive depending on your database configuration) to the columnsand table_columns tables. Depending on the integrity of the data, manual intervention may be required.

  • fabmanager command line is deprecated since Flask-AppBuilder 2.0.0, use the new flask fab <command> integrated with Flask cli.

  • SUPERSET_UPDATE_PERMS environment variable was replaced by FAB_UPDATE_PERMS config boolean key. To disable automatic creation of permissions set FAB_UPDATE_PERMS = False on config.

  • 5453: a change which adds missing non-nullable fields and uniqueness constraints (which may be case insensitive depending on your database configuration) to the metrics and sql_metrics tables. Depending on the integrity of the data, manual intervention may be required.

  • 7616: this bug fix changes time_compare deltas to correctly evaluate to the number of days prior instead of number of days in the future. It will change the data for advanced analytics time_compare so 1 year from 5/1/2019 will be calculated as 365 days instead of 366 days.

Superset 0.32.0

  • npm run backend-sync is deprecated and no longer needed, will fail if called
  • 5445: a change which prevents encoding of empty string from form data in the database. This involves a non-schema changing migration which does potentially impact a large number of records. Scheduled downtime may be advised.

Superset 0.31.0

  • If you use Hive or Presto, we've moved some dependencies that were in the main package as optional now. To get these packages, run pip install superset[presto] and/or pip install superset[hive] as required.

  • Similarly, if you use Celery's flower, gsheetsdb, thrift or thrift-sasl, those dependencies have now been made optional in our package, meaning you may have to install them in your environment post 0.31.0

  • boto3 / botocore was removed from the dependency list. If you use s3 as a place to store your SQL Lab result set or Hive uploads, you may have to rely on an alternate requirements.txt file to install those dependencies.

  • From 0.31.0 onwards, we recommend not using the npm package yarn in favor of good old npm install. While yarn should still work just fine, you should probably align to guarantee builds similar to the ones we use in testing and across the community in general.

Superset 0.30.0

  • 0.30.0 includes a db_migration that removes allow_run_sync. This may require downtime because during the migration if the db is migrated first, superset will get 500 errors when the code can't find the field (until the deploy finishes).

Superset 0.29.0

  • India was removed from the "Country Map" visualization as the geojson file included in the package was very large

  • 5933/6078: changes which add schema and table metadata cache timeout logic at the database level. If left undefined caching of metadata is disabled.

Superset 0.28.0

  • Support for Python 2 is deprecated, we only support >=3.6 from 0.28.0 onwards

  • Superset 0.28 deprecates the previous dashboard layout. While 0.27 offered a migration workflow to users and allowed them to validate and publish their migrated dashboards individually, 0.28 forces the migration of all dashboards through an automated db migration script. We do recommend that you take a backup prior to this migration.

  • Superset 0.28 deprecates the median cluster label aggregator for mapbox visualizations. This particular aggregation is not supported on mapbox visualizations going forward.

  • Superset 0.28 upgrades flask-login to >=0.3, which includes a backwards-incompatible change: g.user.is_authenticated, g.user.is_anonymous, and g.user.is_active are now properties instead of methods.

Superset 0.27.0

  • Superset 0.27 start to use nested layout for dashboard builder, which is not backward-compatible with earlier dashboard grid data. We provide migration script to automatically convert dashboard grid to nested layout data. To be safe, please take a database backup prior to this upgrade. It's the only way people could go back to a previous state.

Superset 0.26.0

  • Superset 0.26.0 deprecates the superset worker CLI, which is a simple wrapper around the celery worker command, forcing you into crafting your own native celery worker command. Your command should look something like celery worker --app=superset.sql_lab:celery_app --pool=gevent -Ofair

Superset 0.25.0

Superset 0.25.0 contains a backwards incompatible changes. If you run a production system you should schedule downtime for this upgrade.

The PRs bellow have more information around the breaking changes:

  • 9825: Support for Excel sheet upload added. To enable support, install Superset with the optional dependency excel

  • 4587 : a backward incompatible database migration that requires downtime. Once the db migration succeeds, the web server needs to be restarted with the new version. The previous version will fail

  • 4565 : we've changed the security model a bit where in the past you would have to define your authentication scheme by inheriting from Flask App Builder's from flask_appbuilder.security.sqla.manager import SecurityManager, you now have to derive Superset's own derivative superset.security.SupersetSecurityManager. This can provide you with more hooks to define your own logic and/or defer permissions to another system as needed. For all implementation, you simply have to import and derive SupersetSecurityManager in place of the SecurityManager

  • 4835 : our setup.py now only pins versions where required, giving you more latitude in using versions of libraries as needed. We do now provide a requirements.txt with pinned versions if you want to run the suggested versions that Superset builds and runs tests against. Simply pip install -r requirements.txt in your build pipeline, likely prior to pip install superset==0.25.0
