Russ Hatch updated CASSANDRA-8408: ---------------------------------- Summary: limit appears to replace page size under certain conditions (was: limit appears to replace page size) > limit appears to replace page size under certain conditions > ----------------------------------------------------------- > > Key: CASSANDRA-8408 > URL: https://issues.apache.org/jira/browse/CASSANDRA-8408 > Project: Cassandra > Issue Type: Bug > Reporter: Russ Hatch > Priority: Minor > > This seems it could be related to CASSANDRA-8403. > When paging a query with: > limit < page size << data size, and querying using an 'IN' clause across > several partitions, I get back several pages of size=limit (instead of the > page size being used). So the limit is being exceeded and it seems to > supplant the page size value, but something is still keeping the total rows > returned down. > To repro, create a table: > CREATE TABLE paging_test ( id int, value text, PRIMARY KEY (id, value) ) > And add data across several partitions (I used 6 partitions). Add a bunch of > rows to each partition (I have 80 total across all partitions). > Perform a paged query using an 'IN' clause across all the partitions, where: > limit < page_size << data size. I used something like: > SELECT * FROM paging_test where id in (1,2,3,4,5,6) LIMIT 9; > (with a page_size of 20 for the query). > What I get returned is three pages of sizes: 9, 9, 8 -- 26 rows in total but > I'm uncertain why. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
