Hi all,
I've been writing a client on Cassandra Thrift API. The client will read almost 1G of data into JVM heap and thus its performance suffers from GC operations. To reduce latency, I'm currently thinking about implementing an off-heap memory (just like that of RowCache) to hold data and manage it myself. The problem is that with Thrift API I read all the data as "List<KeySlice>" directly into heap. Is there a work around? Any other suggestions would also be appreciated. Thanks!
