Spring-xd Redis sink with Collection type MAP


Im trying to implement Redis sink with specific to collection type = MAP

stream create tTEST_GF_SINK --definition "trigger --initialDelay=0 --fixedDelay=1 --timeUnit=MINUTES --payload= 'new Date().toString()' --outputType=application/json | 
  transform --expression='new java.util.Date().toString()'| 
  redis --collectionType=MAP --key=1" --deploy

For all other collection types like LIST , SET ,ZSET stream is able to write into these redis sinks but when I am using MAP as a collection type then it throwing following error on redis_mapkey.

Can any one help me up


Solution

  • With a MAP collection, there are two keys involved; the key the map is stored under and the key the element is stored in the map with.

    The XD module doesn't expose the mapKey as a property. You can either add a header-enricher upstream to set the redis_mapKey header, or you can edit the module's configuration to add the map-key-expression.

    For example, editing xd/modules/sink/redis/config/redis.xml like so...

    <beans:beans profile="use-store-expression">
        <redis:store-outbound-channel-adapter
            map-key-expression="payload.substring(17)"
            key-expression="${keyExpression}" collection-type="${collectionType}"
            channel="input" connection-factory="redisConnectionFactory" />
    </beans:beans>
    

    with...

    xd:>stream create foo --definition "time | redis --collectionType=MAP --key='foo'" --deploy
    

    results in...
