Examples

application start.

eredis_pool:start().
ok

key-value set and get

eredis_pool:q({global, dbsrv}, ["SET", "foo", "bar"]).
{ok,<<"OK">>}

eredis_pool:q({global, dbsrv}, ["GET", "foo"]).       
{ok,<<"bar">>}

Redis Pipeline

Pipeline = [["SET", a, "1"],
     ["LPUSH", b, "3"],
     ["LPUSH", b, "2"]].
eredis_pool:qp({global,dbsrv}, Pipeline).

create new pool with default settings.

eredis_pool:create_pool(pool1, 10).
{ok,<0.64.0>}

and omissible argments(host, port, database, password reconnect_sleep).

eredis_pool:create_pool(pool1, 10, "127.0.0.1", 6379, 1, "abc", 100).
{ok,<0.64.0>}

using new pool

eredis_pool:q(pool1, ["GET", "foo"]).
{ok,<<"bar">>}

delete pool

eredis_pool:delete_pool(pool1).    
ok
