Influxdb memory issue

1

is there a way to optimize influxdb other than switching to TSI?
i am using TSI already it didn’t affect the load(memory usage) much.

@neo1702 some general thoughts:

  • with inmem index, a large number of series can cause high memory usage because the entire index is held in-memory
  • with tsi, a large number of shards can cause high memory usage because there is an index per shard and part of each shard’s index is held in memory.
  • there’s no exact upper limit on number of series with inmem or upper limit on number of shards with tsi because that’s affected by the amount of memory available. Generally though, I would say < 10M series with inmem and < 500 shards with tsi.

How many series and shards do you have?
