Description

Similar to https://github.com/apache/pinot/pull/16953

If we want to change bloomfilter fpp, currently we need to:

  1. remove the bloomfilter config
  2. reload table
  3. add bloomfilter config with new fpp
  4. reload table

Ideally this should happen when the fpp is updated.

We can support this in the BloomfilterIndexHandler
