Tyler Hobbs updated CASSANDRA-11932:
------------------------------------
Summary: Range tombstones generated instead of regular ones between 2.1 and
3.0 nodes (in 3.0 -> 2.1 direction) for some tables (was: Range tombstones
generated instead of regular once between 2.1 and 3.0 nodes (in 3.0 -> 2.1
direction) for some tables)

> Key: CASSANDRA-11932
> URL: https://issues.apache.org/jira/browse/CASSANDRA-11932
> Project: Cassandra
> Issue Type: Bug
> Components: Coordination
> Reporter: Aleksey Yeschenko
> Assignee: Tyler Hobbs
> Fix For: 3.0.x, 3.x
>
>
> Mixed and dynamic Thrift CFs deletions of the dynamic component are being
> translated into range tombstones in 3.0 -> 2.1 direction. On 3.0 side they
> are whole row deletions, and {{LegacyLayout::fromRow(CFMetaData, Row)}} turns
> them into range tombstones even for non-composite, dynamic and mixed Thrift
> CFs. They should be converted into single-cell deletions instead.
> This is not a correctness problem, strictly speaking, and on its own 'only'
> causes digest mismatches on reads (and thus a lot of extra traffic w/ CL >
> ONE) and less efficient representation on wire, though breaks some upgrades
> in combination with CASSANDRA-11930.
> To reproduce, create a mixed CF while both nodes are on 2.1, upgrade one node
> to 3.0, and with cqlsh connected to 3.0 remove some rows. Then do a {{SELECT
> *}} query in cqlsh when connected to 2.1.
