-----------------------------------------
Summary: Validate table properties
Key: HUDI-2240
URL: https://issues.apache.org/jira/browse/HUDI-2240
Project: Apache Hudi
Issue Type: Improvement
Components: Writer Core
Reporter: sivabalan narayanan
Some properties for a given hudi table may not change overtime. As of now, hudi
does not enforce any such constraints, but incompatible changes might result in
errors.
So, creating this ticket to fix that.
* Index type.
** Once simple is enabled, users can't switch back to regular bloom. Other way
round is feasible.
** Once regular bloom is set, users can't switch to global. But other way
round should be doable.
* Key Generators
** Incompatible changes are not allowed. For eg, switching from simple to
timestamp based will run into issues as record keys won't match for merging.
* PreCombine
** ?
* Virtual keys:
** All 3 properties, (record key, partition path and key gen) cannot change
once the table is created with some values.
