Chapter 1. Data Grid Operator 8.5

What is new in 8.5.6.

The 8.5.6 release includes only bug fixes. For more information, see Fixed in Data Grid Operator 8.5.6.

What is new in 8.5.4.

Setting CPU and memory limits in Batch CR

With this update, you can limit the number of CPU requests and memory allocation in a Batch Custom Resource (CR). For example:

apiVersion: infinispan.org/v2alpha1
kind: Batch
metadata:
  name: exampleBatch
spec:
  cluster: infinispan
  configMap: mybatch-config-map
  container:
    cpu: "2000m:1000m" 1
    memory: "2Gi:1Gi"  2

Customizing log display in log traces

You can now customize the log display for Data Grid log traces by defining the spec.logging.pattern field in your Infinispan CR.

If you do not define a custom pattern, the default format is the following:

%d{HH:mm:ss,SSS} %-5p (%t) [%c] %m%throwable%n

For more information, see Adjusting log pattern.

Support for auto scaling with HorizontalPodAutoscaler

StatefulSets or Deployments can now be automatically scaled up or down based on specified metrics by defining a HorizontalPodAutoscaler resource in the same namespace as the Infinispan CR.

For more information, see Auto Scaling.

What’s new in 8.5.3.

Automatic reloading of SSL/TLS certificates

Starting with Data Grid 8.5.1, Data Grid monitors keystore files for changes and automatically reloads them, without requiring a server or client restart, when certificates are renewed.

Therefore, with Data Grid Operator 8.5.3, StatefulSet rolling update is not triggered on key or truststore update in a server when managing Data Grid 8.5.1 Operands because it is not required.

What’s new in 8.5.0.

Ability to configure InitContainer resource

You can now configure the InitContainer resource. Previously, if a LimitRange was in effect for the deployment namespace, then the InitContainer would be restricted to these resource values causing issues such as OutOfMemoryError. You can configure InitContainer resource configuration in the Data Grid CR as follows:

spec:
  dependencies:
    initContainer:
      cpu: "2000m:1000m"
      memory: "2Gi:1Gi"

Ability to define Batch resource CPU and memory request/limits

You can now define CPU and memory request/limits for Batch Job created by the Operator. You can define the resource request/limits in the Batch CR as follows:

apiVersion: infinispan.org/v2alpha1
kind: Batch
metadata:
  name: mybatch
spec:
  cluster: infinispan
  configMap: mybatch-config-map
  container:
    cpu: "2000m:1000m"
    memory: "2Gi:1Gi"

TLSv1.3 encryption for cross-site encryption

The default encryption protocol for cross-site is now TLSv1.3 instead of TLSv1.2.

Ability to define TopologyPodConstraints and Tolerations in StatefulSet

You can now configure more advanced high availability configurations by defining TopologyPodConstraints and Tolerations in spec.statefulSet.

kind: Infinispan
...
spec:
  scheduling:
    affinity:
      ...
    tolerations:
      ...
    topologySpreadConstraints:
      ...

Cache service type removed

RHDG 8.5 removes the Cache service type cache. Instead, use the DataGrid service type to automate complex operations such as cluster upgrades and data migration.

Cloud events removed

RHDG 8.5 removes cloud events integration.
