I want to change my shard duration from 1w to 4w for my default retention policy, and I think the following command should do:
ALTER RETENTION POLICY “autogen” ON “myDatabase” DURATION INF SHARD DURATION 4w DEFAULT
However, it looks like this will not change any of the existing shards, only when creating new ones? Is this correct, and how can I make Influx update/merge existing shards (Four shards into one)?
