how to make bigger SSTable(MemTable) in cassandra 1.2

At first time (almost default options), Cassandra flush 64MB SSTable. But I want to this initial SSTable more larger than 64MB. So, I changed a few cassandra configuration like below (a few times with below config combinations). But not changed .... And memtable_throughput_in_mb option is deprecated in cassandra 1.2.

memtable_total_space_in_mb: 4096 commitlog_segment_size_in_mb: 32 commitlog_total_space_in_mb: 4096

How to make initial(At the time cassandra flush Memtable to SSTable) SSTable size more larger like 128MB or 256MB ?

Thanks.

From the documentation I could find the SSTable size is relative to each column family so you set it using the sstable_size_in_mb:<value> option when you create the CF. For example if you wanted your SStable to be 128mb you could issue the following CQL command:

ALTER TABLE application.users WITH
    compaction_strategy_options:sstable_size_in_mb:10;
