Subject [jira] [Created] (CASSANDRA-2977) add paging to multiget_count
Date Sun, 31 Jul 2011 04:44:09 GMT
add paging to multiget_count

                 Key: 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.

- 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.
