Hi Guys,
I am evaluating Riak as Kay-Value storage where my requirement is to store
huge set of data(more than RAM), so Riak was setup with LevelDB as backend.
Clients were connected using protocol buffer api.
{pb_backlog, 100000}, in app.config
Benchmarking involved 25 Agents doing put/store on single node for 100M
records.
It runs well till 3M but then complete cluster crashes with making all
nodes down.
Following are the System as well as Riak configurations with error & crash
logs
Please help to find what I am missing, I need to test riak & use it in
production as soon as possible.
Nodes: 2 (I know cluster of 5 is best but this is just test setup)
OS: Ubuntu 12.04 32bit
CPU: Core i3
RAM: 4GB
HDD: 500GB
app.config [changes only]
%% eLevelDB Config
{eleveldb, [
{data_root, "/data/riak/leveldb"},
{block_size, 262144}, %%256k
{cache_size, 104857600}, %% 100MB - default cache size 8MB
per-partition
{write_buffer_size, 524288000}, %% 500MB in bytes
