Schema Viewer Drawer (getredash#3291)
* Process extra column metadata for a few sql-based data sources. * Add Table and Column metadata tables. * Periodically update table and column schema tables in a celery task. * Fetching schema returns data from table and column metadata tables. * Add tests for backend changes. * Front-end shows extra table metadata and uses new schema response. * Delete datasource schema data when deleting a data source. * Process and store data source schema when a data source is first created or after a migration. * Tables should have a unique name per datasource. * Addressing review comments. * Update migration file for mixins. * Appease PEP8 * Upgrade migration file for rebase. * Cascade delete. * Adding org_id * Remove redundant column and table prefixes. * Non-existing tables and columns should be filtered out on the server side not client side. * Fetching table samples should be optional and should happen in a separate task per table. * Allow users to force a schema refresh. * Use updated_at to help prune old schema metadata periodically. * Using settings.SCHEMAS_REFRESH_QUEUE * fix for getredash#2426 test * more stable test_interactive_new * Closes #927, #928: Schema refresh improvements. * Closes #934, #935: Remove type from schema browser and don't show empty example column in schema drawer (#936) * Speed up schema fetch requests with fewer postgres queries. * Add column metadata to Athena glue processing. * Fix bug assuming 'metadata' exists for every table. * Closes #939: Persisted, existing table metadata should be updated. * Sample processing should be rate-limited. * Add cli command for refreshing data samples. * Schema refreshes should not overwrite column 'example' field. * refresh_samples() should filter tables_to_sample on the datasource's id being sampled * Correctly wrap long text in schema drawer. Schema Improvements Part 2: Add data source config options. Adding BigQuery schema drawer with data types and samples. Add empty migration to replace the removed schedule_until migration Add merge migration. Co-authored-by: Alison <github@bankofknowledge.net>
