hey,

i have a question and need help...

Description:

I am using cassandra 1.* (3GB ram;4Cors) with 1 node (at first). I am saving different sizes (0.01mb 600mb) of files and indexes in the db and i want to know whats the best size of a value in a column. If the optimal size is smaller then the filesize, i just split it in more columns.

 Problem:

I writed a test to find this size, but i am getting java heap excp. all the time, if i am writing/reading to much values in a row (without pause).

How i can fix this problem? i allready read (http://wiki.apache.org/cassandra/MemtableThresholds) and also the cassandra FAQ

And i know there is no streaming L

 

Would help to decrese the flashsize of the memtable? (whould slow the reading right?)

 

Thanks for help or links:D
