Subject What is the optimal number of tablets for a large table?
Date Fri, 09 Oct 2015 22:53:34 GMT
I read the following from the Accumulo manual on tablet merging

So would the optimal number of tablets for a very large table be close to
the total tservers times the total cores of the machine (or the worker
threads the tservers are config to use--whichever is less)?
