-------------------------------------
Summary: TableSchemaResolver fetches/parses HoodieCommitMetadata
multiple times while extracting Schema
Key: HUDI-4176
URL: https://issues.apache.org/jira/browse/HUDI-4176
Project: Apache Hudi
Issue Type: Bug
Affects Versions: 0.11.0
Reporter: Alexey Kudinkin
Fix For: 0.11.1
We've recently discovered that TableSchemaResolver does a lot of throw-away
work during initialization and basic schema reading performed by Spark
Datasource (see screenshot).
This poses a problem for large tables where HoodieCommitMetadata is of
non-trivial size (100s of Mbs).
We'd minimize amount of throw-away work done by `TableSchemaResolver` and try
to re-use read/parsed commits' metadata as much as possible.
