Subject [jira] [Updated] (CASSANDRA-12516) Interned column identifiers can be overridden incorrectly
Date Tue, 20 Sep 2016 01:31:20 GMT


Stefania updated CASSANDRA-12516:
    Component/s: Local Write-Read Paths

> Interned column identifiers can be overridden incorrectly
> ---------------------------------------------------------
>                 Key: CASSANDRA-12516
>                 URL:
>             Project: Cassandra
>          Issue Type: Bug
>          Components: Local Write-Read Paths
>            Reporter: Aleksey Yeschenko
>            Assignee: Stefania
>             Fix For: 3.10, 3.0.10
> As discovered by [~Stefania] in CASSANDRA-12423, our use of {{ColumnIdentifier.internedInstances}}
to map byte buffer column names to column identifiers is incorrect. It's possible for two
non-equal {{ColumnIdentifier}} instances to have the same {{ByteBuffer}} as raw name, and
yet different text representations, due to different column name types, leading to hard to
debug correctness issues.
> Should either amend the map to have the type as part of the key, or limit the use of
that map.
