This service relies on the WATCH, MULTI, and EXEC commands in Redis, which are not fully supported when Redis is clustered. As a result, this service can only be used with a Redis Connection Pool that is configured for standalone or sentinel mode. Sentinel mode can be used to provide high-availability configurations.</p><h3>Tags: </h3><p>redis, distributed, cache, map</p><h3>Properties: </h3><p>In the list below, the names of required properties appear in <strong>bold</strong>.
