Vinoth Chandar commented on HUDI-2151:
--------------------------------------
Should this be turned to true?
{code:java}
public static final ConfigProperty<String> MERGE_ALLOW_DUPLICATE_ON_INSERTS =
ConfigProperty
.key("hoodie.merge.allow.duplicate.on.inserts")
.defaultValue("false")
.withDocumentation("When enabled, we allow duplicate keys even if inserts are
routed to merge with an existing file (for ensuring file sizing)." +
" This is only relevant for insert operation, since upsert, delete operations
will ensure unique key constraints are maintained.");

> Project: Apache Hudi
> Issue Type: Sub-task
> Components: Code Cleanup, Docs
> Reporter: Vinoth Chandar
> Assignee: Vinoth Chandar
> Priority: Major
>
> We have quite a few configs which deliver better performance or usability,
> but guarded by flags.
> This is to identify them, change them, test (functionally, perf) and make
> them default
>
> Need to ensure we also capture all the backwards compatibility issues that
> can arise
