-------------------------------------------
Summary: Make custom filtering more extensible via custom classes
Key: CASSANDRA-11295
URL: https://issues.apache.org/jira/browse/CASSANDRA-11295
Project: Cassandra
Issue Type: Improvement
Components: Local Write-Read Paths
Reporter: Sam Tunnicliffe
Assignee: Sam Tunnicliffe
Priority: Minor
Fix For: 3.x
At the moment, the implementation of {{RowFilter.CustomExpression}} is tightly
bound to the syntax designed to support non-CQL search syntax for custom 2i
implementations. It might be interesting to decouple the two things by making
the custom expression implementation and serialization a bit more pluggable.
This would allow users to add their own custom expression implementations to
experiment with custom filtering strategies without having to patch the C*
source. As a minimally invasive first step, custom expressions could be added
programmatically via {{QueryHandler}}. Further down the line, if this proves
useful and we can figure out some reasonable syntax we could think about adding
the capability in CQL in a separate ticket.
