Hi,
I need to know the complexity for getting data in hbase or adding data.

In my software is that ok if I play a lot with hbase: open a table, open another
one, get something, put...

What is the cost of accessing in a table? cost of the put?get?

I searched on the web and I found nothing...
Thanks,

The only real way to find this out for your application is to do your
own performance testing - this is because the numbers are totally
dependent on your data size, number of requests, hardware, network,
etc etc.

If you are just looking to get a rough idea, search for "hbase
performance benchmarks" and you should get quite a few hits.
Here's one http://hstack.org/hbase-performance-testing/
If you have a test cluster setup, you could use YCSB to run benchmarks
with varying load patterns and data sizes.

Here's a recent thread that also gives you some numbers from OpenTSDB.

Hi there-

Review the HBase book too.
