--------------------------------------
satishkotha opened a new pull request #3475:
URL: https://github.com/apache/hudi/pull/3475
## What is the purpose of the pull request
Add range index support with metadata table
## Brief change log
* This is a WIP PR primarily used for data collection.
* Lot of fundamental metadata table bottlenecks have to be resolved. For
example, bootstrapping rangeIndex for 30 partitions of large table (4000
columns) runs into memory issues and driver result too large errors. We also
need to implement async metadata table design in V2
* Tried to implement primitive bucketing by column name to improve index
locality
* Only implemented commit integration. Clean and other action integration
needs to be added.
## Verify this pull request
* Verified end-to-end by bootstrapping range index on few partitions of
large table (4000 columns)
*
* Unit Tests TBD
