> Key: CASSANDRA-19368
> URL: https://issues.apache.org/jira/browse/CASSANDRA-19368
> Project: Cassandra
> Issue Type: Improvement
> Components: Feature/2i Index
> Reporter: David Capwell
> Priority: Normal
> Fix For: 5.x
>
>
> 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
