Subject Finding big rows
Date Tue, 10 May 2011 08:41:25 GMT

I've noticed very nice stats exposed with JMX. I was quite shocked when I saw that MaxRowSize
was about 400MB (it was expected to be several MB).
What is the best way to find keys of such big rows?

I couldn't find anything so I've written simple program to dump sizes from Index files (see
and got the keys, but when I used cassandra-cli to get such columns it said "Returned 0 results.".
I've realised that my app creates such big rows because it can't read them from Cassandra
and recreates them every time.

Are there any tuneable limits for getting whole row?  Any limits on supercolumns?
