Support of redis cluster in nifi - save and fetch

Chhavi — Tue, 23 Aug 2022 03:43:50 GMT

I have read about support of redis sentinel and standalone redis in Apache nifi but is there any way I can integrate clustered nifi for storing and fetching the value ?

@Chhavi

Your question is not very clear.

is there any way I can integrate clustered nifi for storing and fetching the value

Storing and fetching what value?

NiFi includes a couple Redis controller services:
RedisConnectionPoolService
RedisDistributedMapCacheClientService

For example,
The RedisDistributedMapCacheClientService could be used by the PutDistributedMapCache NiFi processor to write values to Redis. The FetchDistributedMapCache NiFi processor could be used to fetch values from Redis.

I was looking for a way to put/fetch data from Redis in cluster mode in NiFi and came across this question. RedisConnectionPoolService supports cluster mode but RedisDistributedMapCacheClientService 1.16.3 doesn't. Is there an alternative service that I can use for that?

Thanks

I am also experiencing this issue when attempting to write data to a redis in cluser mode. Did you find a solution or workaround @sofronic ?
