Try using setCaching and setBatching. These help you to avoid the number of calls that happens from the client to the server for every result/row fetched. Regards Ram -Original Message- From: sameer [mailto:sameer_therat...@infosys.com] Sent: Thursday, June 28, 2012 11:14 AM To:

(moving this to the user mailing list, with the dev one in bcc) From what you said it should be customerid_MIN_TX_ID to customerid_MAX_TX_ID But only if customerid size is constant. Note that with this rowkey design there will be very few regions involved, so it's unlikely to be parallelized.

Re: Can a server function make a rpc call to the corresponding client

2012-06-28 Thread Dishant A
Hi Anoop, I haven't used co-processor package before but my understanding is that, it is the client which calls desired region-servers instead of server calling the client. Can you please explain how a server-side function can call/instantiate co-processor. Thanks, Dishant On Thu, Jun 28, 2012

Of course I would also venture the opinion that any HBase change which uses multi() should be considered experimental, as well as use of the SASL authentication. On that latter point, use of it is optional. I would caution us to also implement use of multi for optimization of MTTR or improvement

+1 We can also look for issues that are still open (and are delaying 3.4 to be marked as stable), and make the call whether we can use it or not. On Thu, Jun 28, 2012 at 11:48 AM, Andrew Purtell apurt...@apache.org wrote: ZooKeeper dev consensus is: fwiw during the summit meetup we took a poll

I put this on the jira too, but the algo I found whittled down a stream of 10 million items down to ~19.5k samples. With each sample at ~36B, that's ~685KiB. There's a bit more from using a LinkedList and general bookkeeping. Since the estimator is reset every O(minutes) window, and I doubt very
