> Key: PHOENIX-5018
> URL: https://issues.apache.org/jira/browse/PHOENIX-5018
> Project: Phoenix
> Issue Type: Bug
> Affects Versions: 4.14.0, 5.0.0
> Reporter: Geoffrey Jacoby
> Assignee: Kadir OZDEMIR
> Priority: Major
>
> When doing a full rebuild (or initial async build) on an index using the
> IndexTool and PhoenixIndexImportDirectMapper, we generate the index mutations
> by creating an UPSERT SELECT query from the base table to the index, then
> taking the Mutations from it and inserting it directly into the index via an
> HBase HTable.
> The timestamps of the Mutations use the default HBase behavior, which is to
> take the current wall clock. However, the timestamp of an index KeyValue
> should use the timestamp of the initial KeyValue in the base table.
> Having base table and index timestamps out of sync can cause all sorts of
> weird side effects, such as if the base table has data with an expired TTL
> that isn't expired in the index yet.
