-----------------------------------------
Summary: Add way for SAI to disable row to token index so internal
tables may leverage SAI
Key: CASSANDRA-19368
URL: https://issues.apache.org/jira/browse/CASSANDRA-19368
Project: Cassandra
Issue Type: Improvement
Components: Feature/2i Index
Reporter: David Capwell
Internal tables tend to use LocalPartitioner and may not actually have murmur
tokens but rather LocalPartitioner, which is variable length bytes tokens! For
internal use cases we don’t always care about paging so don’t really need this
index to function.
The use case motivating this work is for Accord, we wish to add a custom SAI
index on the system_accord.commands#routes column. Since this logic is purely
internal we don’t care about paging, but can not leverage SAI at this moment as
it hard codes murmur tokens, and fails during memtable flush
