Summary: Support writing SAI Indexes
Key: CASSANALYTICS-31
URL: https://issues.apache.org/jira/browse/CASSANALYTICS-31
Project: Apache Cassandra Analytics
Issue Type: New Feature
Reporter: Doug Rohrer
There's a collection of things that need to be done in Analytics to support SAI
Indexes on the write path:
* include index defs in {{CQLSSTableWriter}} setup
* Confirm analytics library sends all necessary files on write
* Support SAI indexes {_}only{_}, not any arbitrary index
* Fail if index components are not available/readable; need some mechanism to
read across a StorageAttachedIndex file and validate that the structure is
sound / correct w/out corruption
* Import SAI indexes into C* in addition to sstables
* Importer able to skip validation of files
For the read path, we believe that SAI indexes would only be useful if we
expand support for predicate pushdown further, which shouldn't be a blocker for
1.0.
