Environment
- EDR Servers: All versions
Question
In the EDR cluster environment, when should the Primary server be eventless?
Answer
It depends on the cluster's resources, incoming data and integrations. Routinely, when the third or fourth minion is introduced to the cluster the Primary node becomes eventless.
Additional Notes
- In small clusters (1-2 minions), the Primary can perform the role of a Solr indexing server (eventful).
- Clusters handling more than 60,000 sensors, or four minions, must have a dedicated Primary node that is not performing minion duties.
- Solr clustering is performed by breaking up a single Solr core into multiple cores called shards. Shards are evenly distributed to indexing nodes for individual management and distributed querying.
