Cassandra, Elasticsearch, Kafka, and Hazelcast
We just received a message about extending support for Hazelcast and it mentions a whole bunch of other things. How do I check if my system is using any of these components?

Cassandra: Cassandra is ideally used in Pega CDH unless there's any explicit requirement. So if you're using CDH, then your system is using Cassandra DB.
Elasticsearch:
- Click Records > SysAdmin > Dynamic System Settings.
- Verify that Elastic search is enabled by checking that the value for the following dynamic settings is true:
- indexing/distributed/enabled
- indexing/distributed/index_enabled
- indexing/distributed/search_enabled
- indexing/distributed/search/fuzzy/enabled
- indexing/useDataInstances
Kafka: Kafka is a high-throughput and low-latency platform for handling real-time data feeds that can be used as input for event strategies in Pega. Its normally used in decision management but in normal scenarios queue processing runs on Kafka from Pega version 8 onwards. So technically your system is using Kafka.
Hazelcast: Pega low-level features such as agents, Job Scheduler, and REST service rules use Hazelcast to cache or store the data. So technically your system is using Hazelcast.
