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.
