---------------------------------------
Summary: Overload SecondaryIndex#indexes to accept the column
definition name
Key: CASSANDRA-9314
URL: https://issues.apache.org/jira/browse/CASSANDRA-9314
Project: Cassandra
Issue Type: Improvement
Components: Core
Reporter: Sergio Bossa
Assignee: Sergio Bossa
In order to avoid rebuilding indexes when no columns are actually indexed
(originally implemented in CASSANDRA-9196), CASSANDRA-9281 hinted at overriding
{{SecondaryIndex#getColumnDefs}} to "filter out" indexes that shouldn't be
rebuilt; unfortunately, I believe this would be quite wrong for safety reasons,
as it could have side effects on other methods relying on {{getColumnDefs}}
returning a stable set, and API consistency ones, as it would be confusing to
have {{getColumnDefs}} behave differently based on runtime conditions, possibly
ignoring {{addColumnDef}} calls.
I believe {{SecondaryIndex#indexes}} is still the best candidate to act as a
filter predicate, and I propose to overload it to accept a column definition
name for all those cases (i.e. index rebuilding) missing a full cell name.
