-------------------------------------------
Summary: Promote the use of IFilter for internal commands
Key: CASSANDRA-4308
URL: https://issues.apache.org/jira/browse/CASSANDRA-4308
Project: Cassandra
Issue Type: Improvement
Components: Core
Reporter: Sylvain Lebresne
Assignee: Sylvain Lebresne
Priority: Minor
Fix For: 1.2
All read commands (the IReadCommand) work on slice and names filters, but none
of them uses the SliceQueryFilter and NamesQueryFilter classes
(RangeSliceCommand uses SlicePrediate from thrift and {SliceFrom,
SliceByNames}ReadReadCommand interns the arguments).
The main problem of that is that it follows that those command don't share the
serialization code for the column filters. Which isn't good for code reuse, but
also makes it a pain to add new fields to the filter SliceQueryFilter (which
CASSANDRA-3885 will need, but probably CASSANDRA-3647 too).
