manojpec opened a new pull request #3904:
URL: https://github.com/apache/hudi/pull/3904
## What is the purpose of the pull request
- Today, base files have bloom filter at their footers and index lookups
have to load the base file to perform any bloom lookups. Though we have
interval tree based file purging, we still end up in significant amount
of base file read for the bloom filter for the end index lookups for the
keys. This index lookup operation can be made more performant by having
all the bloom filters in a new metadata partition and doing pointed
lookups based on keys.
- This PR adds the basic infrastructure for initializing the new bloom filter
metadata partition, stubs for write and read code paths
