Redis Connection

Description

A Redis Connection describes how Apache Hop connects to Redis in Standalone, Sentinel or Cluster mode. Connections are managed in the Metadata perspective and serialized as JSON under:

metadata/redis-connection/

Use the Test button to verify connectivity with a Redis PING.

The editor is split into two groups:

  • Connection config — topology, authentication and timeouts (fields change with deployment mode)

  • Pool config — shared Lettuce connection-pool settings for all three modes
