Thomas D'Silva commented on PHOENIX-2478:
-----------------------------------------

Would using a wildcard row key allow DML operations that write two different 
rows to succeed? Seems like the last alternative which allows read/read 
conflicts but doesn't allow read/write or write/write is required for that 
scenario to work.

> Rows committed in transaction overlapping index creation are not populated

> For a reproducible case, see IndexIT.testCreateIndexAfterUpsertStarted() and 
> the associated FIXME comments for PHOENIX-2446.
> The case that is failing is when a commit starts before an index exists, but 
> commits after the index build is completed. For transactional data, this is 
> problematic because the index gets a timestamp after the commit of the data 
> table mutation and thus these mutations won't be seen during the commit. 
> Also, when the index is being built, the data hasn't yet been committed and 
> thus won't be part of the initial index build.
