> Key: CASSANDRA-11031
> URL: https://issues.apache.org/jira/browse/CASSANDRA-11031
> Project: Cassandra
> Issue Type: New Feature

> Reporter: ZhaoYang

> Attachments: CASSANDRA-11031.patch

>
> Currently, Allow Filtering only works for secondary Index column or
> clustering columns. And it's slow, because Cassandra will read all data from
> SSTABLE from hard-disk to memory to filter.
> But we can support allow filtering on Partition Key, as far as I know,
> Partition Key is in memory, so we can easily filter them, and then read
> required data from SSTable.
> This will similar to "Select * from table" which scan through entire cluster.
> CREATE TABLE multi_tenant_table (
> tenant_id text,
> pk2 text,
> c1 text,
> c2 text,
> v1 text,
> v2 text,
> PRIMARY KEY ((tenant_id,pk2),c1,c2)
> ) ;
> Select * from multi_tenant_table where tenant_id = "datastax" allow filtering;
