major overhaul:

  • implemented chainable transactions, with auto-returnRessource on exec.
  • implemented redundancy
  • implemented singleJedis-UniJedis, with option to add slaves-List lateron.
  • option to use select just as with normal Jedis
  • some bugs removed (beware of those min <-> max).

ib84 commented
  • setting slave list after construction now really works, assuming updated RoundRobinPool
  • exposing some relevant options of internalPool: - setMinIdle, setMaxIdle, setWhenExhaustedGrow
