NOTE: Patch release 23.4.1 coming up
We identified some issues with the 23.4 release and will issue a patch release 23.4.1 on May 17 2023
Original content
Stackable Data Platform (SDP) Release 23.4 is now publicly available!
Highlights
The focus in this release is on Cluster Operation, the Status field and default/custom Affinities.
Cluster Operation
The first part of Cluster Operations has been implemented in all Stackable Operators where it is relevant. This supports pausing the cluster reconciliation (not applying any changes to the Kubernetes resource) and stopping the cluster completely (setting all replicas of StatefulSets, Deployments or DaemonSets to zero and therefore deleting all Pods belonging to that cluster whilst leaving the data intact).
Status Field
Operators of the Stackable Data Platform create, manage and delete Kubernetes resources: in order to easily query the health state of the products Stackable Operators use several predefined condition types to capture different aspects of a product's availability.
Default / Custom Affinities
In Kubernetes there are different ways to influence how Pods are assigned to Nodes. In some cases it makes sense to co-locate certain services that communicate a lot with each other, such as HBase regionservers with HDFS datanodes. In other cases it makes sense to distribute the Pods among as many Nodes as possible. There may also be additional requirements e.g. placing important services in different racks or data-centers. This release implements default affinities that should suffice for many scenarios out-of-the box, while also allowing for custom affinity rules at a role and/or role-group level.
New product-specific features
We have also added new product-specific features such as:
Learning Stackable
