Hi everyone,
I have a weird, invalid situation with my cluster. I have a table on which
I'm running some SELECTs with WHERE clause filtering on cluster columns,
but the rows are not getting filtered out.
Look:
select * from page_view where website_id = xxx and user_id = 'some_user'
and page_id =0; -- tried also page_id<0 >0
website_id | user_id | page_id | ...
------------+-----------+----------+----
xxx | some_user | 21044533 | ...
...more rows here, none with page_id=0
The filtering on other (partition) columns runs fine. Only the clustering
column is somewhat malfunctioning.
Important is, how I got to this table:
1. I collected data with Cassandra version 2.0.8
2. I snapshotted the data, and removed the main copy from cluster's data.
3. I upgraded cluster to version 2.1.0-rc4
4. I've recreated the schema of tables in new version.
5. I ran sstableloader on the data to load data to new upgraded cluster.
6. I spotted the problem with filtering.
7. I've tried to run nodetool repair, nodetool upgradesstables -a , neither
helped.
Do you have any ideas how to curate my data?
It might be cumbersome, but possible to just copy data out (to e.g. json)
and back in. But anyway, I believe it might be a bug in 2.1.0-rc4. Do you
have at least ideas on how to investigate what the problem is?
Thank you for any help,
