KubeBlocks v0.7.0

KubeBlocks 0.7.0 (2023-11-06)

We're thrilled to announce the official release of KubeBlocks v0.7.0! 🚀 🎉 🎈

This version supports the function of referencing external components, making it possible to assemble building blocks - add-ons more flexibly.

Backup is decoupled from the cluster with a separate API, and three new object storage services from public cloud providers are added as backup storage options.

Thanks to the support of our community, KubeBlocks has included 31 open-source database engines, including MariaDB, Elasticsearch, Pulsar, Pika and more, providing more choices for you.

We would like to extend our appreciation to all contributors who helped make this release happen.

Highlights

Support referencing external components

The new feature of referencing external components brings greater flexibility to KubeBlocks clusters, allowing them to be assembled like building blocks to create new clusters. Currently, this function can be applied to two scenarios. Firstly, you can reference external components, such as external Zookeeper, that are not created and managed by KubeBlocks. You just need to define the service description and Kubernetes deployment is not required. Another scenario is that clusters created by KubeBlocks can be referenced as components by other clusters. For example, a Redis Sentinel cluster can be referenced by other Redis Replication clusters for managing high-availability.

Decouple cluster and backup #4877, #4494

The backup policy supports customizing backup methods, allowing you to specify a backup method when creating a backup. The BackupTool has been replaced with the ActionSet CRD, which defines actions for backup and restore. Three new object storage services, GCS, OBS, and COS, have been added as backup storage options. Besides, BackupSchedule is added to decouple automatic scheduling configurations from BackupPolicy that can be used for both automatic and manual backup.

Support Pika v3.5

Pika, developed by Qihoo, is an open-source NoSQL database that is compatible with Redis interfaces such as string, hash, list, zset, and set operations. It offers a cost advantage in 100 GB level and larger data volumes. Switching from Redis to Pika is seamless, as it maintains the same usage and operation habits. Currently, KubeBlocks has already supported deploying the sharded cluster mode from Pika v3.5. After a cluster is created by KubeBlocks, Pika is automatically added to the Codis cluster with rebalancing applied. KubeBlocks can also automatically manage Pika Primary-Secondary clusters, which can automatically add one primary with one or multiple secondaries.

KubeBlocks v0.6.0

KubeBlocks 0.6.0 (2023-08-18)

We are happy to announce the official release of KubeBlocks 0.6.0! 🚀 🎉 🎈

This version supports stream computing engines Kafka and Pulsar and supports MySQL read-write splitting, introduces an interactive parameter configuration method.

We would like to extend our appreciation to all contributors who helped make this release happen.

Highlights

• KubeBlocks supports Kafka v3.3
  • Apache Kafka is an open-source distributed event storage and streaming computing system that provides high reliability, throughput, and low latency for data pipelines, streaming analysis, and data integration. It is widely used in log collection and metric monitoring scenarios. KubeBlocks supports Kafka v3.3, which announced that KRaft meets production requirements, providing better partition scalability and resilience, and saving the additional costs of ZooKeeper. In addition, KubeBlocks also supports pushing data changes from MySQL and PostgreSQL to Kafka, making it easier for users to further process and handle the data.
• KubeBlocks supports Pulsar v2.11
  • Apache Pulsar is an open-source distributed messaging and stream processing platform. It aims to provide scalability, high performance, and reliability to meet the needs of modern data processing and real-time messaging. KubeBlocks supports Apache Pulsar v2.11, and compared to traditional deployment methods, KubeBlocks can automate fault tolerance, scaling, and other day2 operations.
• KubeBlocks supports MySQL read-write splitting
  • Read-write splitting is designed to improve the read-only processing capability of a MySQL database cluster. All write queries are sent to the master node, while read-only queries that do not modify data are distributed to multiple slave nodes. Read-write splitting is used together with the MySQL Raft Group cluster, which automatically detects changes in the master node and uses the current master node of the cluster to achieve failover. Set read_write_splitting_policy as read-write splitting at the global or session level, and the default policy is LEAST_CURRENT_OPERATIONS, which routes read-only queries to the slave node with the least active operations. The MySQL Raft Group cluster supports up to 5 nodes.

Breaking changes

• For KubeBlocks v0.6, newly created Redis and PG clusters need password to connect, while v0.5 used to allow password-free login
• For KubeBlocks v0.6, the backup and restore function is updated greatly. You need to manually upgrade the 0.5 version cluster to 0.6 and update backupPolicy to use the new function.
• For KubeBlocks v0.6, since password-free login function is not supported for Postgres cluster, when restoring cluster upgraded from v0.5, if the new restored cluster is in creating status for a long time, you can check the pod logs to see whether there is password authentication failed error, you can update password to fix this.

Acknowledgements

Thanks to everyone who made this release possible!

What's New

Pulsar

• Cluster lifecycle management and operation management, supporting the creation of Pulsar clusters, cluster deletion, cluster restarting, horizontal scaling, vertical scaling, volume expanding, and parameter modifying.
• For monitoring, support performance monitoring of CPU, memory, network read/write traffic, and more for ZooKeeper, BookKeeper, and Broker.

Kafka

• Cluster lifecycle management and operation management, supporting cluster creation, deletion, horizontal scaling, vertical scaling, volume expanding, and modifying parameters.
  • Horizontal scaling: In combined mode, broker replicas support 1, 3, or 5 copies. In separated mode, brokers support 1 to 100 copies and Kafka controllers support 1, 3, or 5 copies.
• For monitoring, supports performance monitoring of Broker's CPU, memory, network read/write traffic, etc.

MySQL

• MySQL RaftGroup Cluster supports Switchover
• MySQL RaftGroup Cluster supports MySQL read-write splitting.
• Data Recovery, Non-Destructive Recovery by Point-in-time（PITR）. It's a beta feature.
• Support proxy enable when creating cluster. (Beta)
  • The default specification of Vitess proxy can meet the vast majority of user scenarios. Vitess proxy automatically triggers resource increase or decrease based on changes in database nodes and node specifications, without manual operation. The CPU of Vitess proxy is 1/6 of the total number of CPU cores in the cluster nodes (three nodes), rounded up to 0.5c granularity, with a minimum of 0.5c and a maximum of 64c. The default number of replicas is 1, and currently, modifying the number of replicas is not supported
  • Connection Address: The proxy has a default connection address that supports read-write splitting. The expose command can generate VPC addresses and public network addresses for the proxy connection address.
  • Supports setting Vitess proxy read-write splitting policies.

PostgreSQL

• Support switchover for PG Replication Cluster
• Built-in pgBouncer

MongoDB
