Is it smart enough to manage itself? Or does it require human babysitting?

There are some subscribers to this mailing list that like to download and try things early. I was directing those subscribers to the GitHub branch that contains the work-in-progress code. flexcache is a new method for sizing / accounting the memory used by leveldb. It replaces the current method completely. flexcache is therefore not an option, but an upgrade to the existing logic. Again, the detailed discussion is here: ttps://github.com/basho/leveldb/wiki/mv-flexcache Matthew On Oct 18, 2013, at 12:33 PM, Dave Martorana <d...@flyclops.com> wrote: Matthew, For we who don't quite understand, can you explain - does this mean mv-flexcache is a feature that just comes with 2.0, or is it something that will need to be turned on, etc? Thanks!

No serious enterprise technology should just consume everything and crash.

Yes, the app.config needs some adjustment to achieve happiness for you: - change ring_creation_size from 64 to 16 (remove the % from the beginning of the line) - add this line before "{data_root, <path>}" in eleveldb section: "{max_open_files, 40}," (be sure the comma is at the end of this line). Good luck, Matthew On Oct 17, 2013, at 8:23 PM, ZhouJianhua <jh.z...@outlook.com> wrote: Hi I installed riak v1.4.2 on ubuntu12.04(64bit, 4G RAM) with apt-get, run it with default app.conf but change the backend to leveldb, and test it with https://github.com/tpjg/goriakpbc . Just keep putting (key, value) to an bucket, the memory always increasing, and in the end it crashed, as it cannot allocate memory. Should i change the configuration or other? _______________________________________________ riak-users mailing list riak-users@lists.basho.com http://lists.basho.com/mailman/listinfo/riak-users_lists.basho.com _______________________________________________ riak-users mailing list riak-users@lists.basho.com http://lists.basho.com/mailman/listinfo/riak-users_lists.basho.com
