-----------------------------------------
Summary: Add guardrail to disallow bulk import of tables with
legacy 2i's
Key: CASSANDRA-21241
URL: https://issues.apache.org/jira/browse/CASSANDRA-21241
Project: Apache Cassandra
Issue Type: Improvement
Reporter: Josh McKenzie
The import logic for legacy 2i can have a very long window where an index is
stale after a table has data bulk imported into it (notably, SAI doesn't have
this same issue). To protect against this, we should have a guardrail operators
can configure, on by default (to match the default behavior in
cassandra-analytics where we've been too narrowly guardrailing this in the
past), that disallows bulk loading to tables with 2i.
Part of this is that we're adding a flag to open up this restriction on the
spark bulk writer side, but that bulk writer is just a client of bulk sstable
loading in C* like any other. If analytics needs that guardrail to protect
against surprise stale reads from users, so too do any other users of the bulk
importing facilities on the C* side.
