C. Scott Andreas updated CASSANDRA-14680:
-----------------------------------------
Component/s: Secondary Indexes
> Built-in 2i implementation applies updates non-deterministically
> ----------------------------------------------------------------
>
> Key: CASSANDRA-14680
> URL: https://issues.apache.org/jira/browse/CASSANDRA-14680
> Project: Cassandra
> Issue Type: Bug
> Components: Secondary Indexes
> Reporter: Chris Lohfink
> Priority: Major
> Fix For: 3.0.x, 3.11.x, 4.0.x
>
>
> Spotted by [~cnlwsu] during CASSANDRA-14664 review, and confirmed by me and
> [~beobal] separately.
> {{Keyspace.applyInternal()}} generates {{nowInSeconds}} from local time at
> the time of mutation application - which can happen at quite a delay from
> that mutation creation (think streaming path, hints, batchlog replay). That
> {{nowInSeconds}} value is later used by {{CassandraIndex}} {{Indexer}} to
> determine liveness of cells and also used for some of generated tombstones.
> Depending on when {{Keyspace.applyInternal()}} call happens, you'll see
> varying results in the internal 2i table, which sounds problematic. The
> values should be derived from the cells and liveness info in the partition
> updates exclusively.
