[jira] [Created] (CASSANDRA-2977) add paging to multiget_count
add paging to multiget_count
----------------------------
Key: CASSANDRA-2977
URL: https://issues.apache.org/jira/browse/CASSANDRA-2977
Project: Cassandra
Issue Type: Improvement
Reporter: Jonathan Ellis
Priority: Minor
CASSANDRA-2894 added paging to the single-row get_count. But, this does not help multiget_count since they are different code paths.
Options:
- do nothing; multiget_count is a fairly obscure call, and there is no sane way to support it in CQL so will become even more obscure
- translate multiget_count into a series of get_count calls; high-latency, if done naively
- translate get_count into a single multiget_count, and perform the paging in StorageProxy. HIGHLY painful to manage paging multiple rows independently, in the general case.

Jonathan Ellis resolved CASSANDRA-2977.
---------------------------------------
Resolution: Won't Fix
Wontfixing because I'd rather spend the time improving CQL.
