Subject Re: Cassandra Read Timeout
Date Tue, 24 Feb 2015 16:50:25 GMT
The structure is the same , the CFs are super column CFs , where key is
long  ( timestamp to partition the index , so each 11 days new row is
created ) , super Column is int32 and columns / values are timeuuids.I am
running same queries , getting reversed slice by raw key and super column.
The number of reads is relatively high on second CF since i am testing it
several hours already , most of time there are no requests for read on both
of them , only writes.There is at most 1 read request in 20-30 seconds so
it should not create a load.There is also no reads ( 0 before and 1 after )
pending on tpstats.
Please also note that queries on different row same super column , and same
row , different super column are working , and if i am not mistaken
cassandra is loading complete raw including all super columns to memory (
either any request to this row should fail if this would be a memory
problem , or none...).

Best regards
