HBase Read and Write Performance Conversation

Increase both read n write performance.

Sure will add more nodes.

Do you want to increase performance for reads, writes or both ?

Your table is presplit. Can you add more node to leverage the multiple

regions ?

If you need better performance for reads, consider using BucketCache.
