Summary

I'm trying to figure out how to use rebar to:

• create erlang project
• add a dependency on an erlang module from github
• start the app via the erl console
• create a release and start the app from the release (via the generated scripts)

Riak tricks

Bitcask, fill the key storage memory up by continously storing lots of objects with big keys and small data.

while true ; 
    do echo run ; 
 curl -XPUT -H "Content-Type: application/text" -d 'foo' "http://127.0.0.1:8098/riak/default/test$(date +"%s")${RANDOM}${RANDOM}$(seq 1 2200 | tr -d '\n') " ;

/**
 * Given an operation that produces a T, returns a Future containing the result of T, unless an exception is thrown,
 * in which case the operation will be retried after _delay_ time, if there are more possible retries, which is configured through
 * the _retries_ parameter. If the operation does not succeed and there is no retries left, the resulting Future will contain the last failure.
