The Picodata development team is pleased to announce the release of Picodata 22.11.0, our core software product. This new version is the result of several months of hard work and includes some new useful features that we implemented recently.
- New algorithm for cluster management. Instances are managed and configured by a centralized body that we call ‘governor’.
- Instance’s states are now referred to as ‘grades’. This new term more clearly denotes how an instance is currently perceived by other instances (eg. how they are configured in its regard) rather than what it assumes about itself. The governor is responsible for updating current grades to target ones by applying new instances’ configurations in time.
- The main and long-awaited innovation in Picodata 22.11.0 is the introduction of a built-in
vshardlibrary, which allows you to store and manipulate data in the database. Sharding support means that once a replicaset is up to the given replication factor, Picodata will automatically re-balance data buckets across replicasets. Everything happens under the hood, completely transparent to Picodata users.
- This new release introduces clusterwide schema and data migrations
- Unnecessary instances can now be expelled using the
picodata expelcommand in order to shrink the cluster.
