Cleanup rdb_data folder in milvus

[mananpreetsingh]

Environment:

K8: 1.30
Milvus version: v2.4.12
Deploy Mode: STANDALONE

Current Behavior
The size of the rdb_data folder keeps increasing and never cleans up auto.

Issue

It seems following config in helm chart is not being supported any more:

standalone:
  rocksmq:
      retentionTimeInMinutes: 60
      retentionSizeInMB: 64
      rocksmqPageSize: "2147483648" ## 2 GB
      lrucacheratio: 0.06 ## rocksdb cache memory ratio

Seems it used to support in helmchart version 3.. and in Helm chart 4.0.0 it stopped supporting. Wonder hoe can we clean up rdb_data folder in milvus either via helm chart config or via cli some how?

In latest helm I was able to do it like:

extraConfigFiles:
  user.yaml: |+
    rocksmq:
      retentionTimeInMinutes: 4320
      retentionSizeInMB: 256
      rocksmqPageSize: "67108864" ## 64 MB
      lrucacheratio: 0.06 ## rocksdb cache memory ratio
      compactionInterval: 86400
