Hello everyone!
I have a strange problem with Cassandra (v1.0.5, one node, 8GB, 2xCPU):
a query asking for each key from a certain (super) CF results in timeout
and almost dead cassandra after that (it's somewhat alive, but does not
return any data - has to be restarted).
CF details:
Column Family: ************
SSTable count: 11
Space used (live): 4254606435
Space used (total): 4254606435
Number of Keys (estimate): 1408
Memtable Columns Count: 26923
Memtable Data Size: 25420941
Memtable Switch Count: 16
Read Count: 0
Read Latency: NaN ms.
Write Count: 39649
Write Latency: 0.032 ms.
Pending Tasks: 0
Bloom Filter False Postives: 0
Bloom Filter False Ratio: 0.00000
Bloom Filter Space Used: 30416
Key cache capacity: 24
Key cache size: 24
Key cache hit rate: NaN
Row cache: disabled
Compacted row minimum size: 125
Compacted row maximum size: 1155149911
Compacted row mean size: 38855255
Nothing suspicious in the logs. The problem is fully replicable.
I've spent some time searching for similar issues - haven't found any.
Are there any debug options I could turn on to find out more? Other
suggestions/thoughts?
Thanks in advance,
Wojtek
