Jedis connection retry

[Atta Beit]

I am trying to write reconnect logic when my application loses connection to redis when Redis fails over. Does Jedis provide hooks to retry connection?

[Sazzadul]

No.

This does sound similar to the functionality available via JedisPool though. Create a pool of 1 and whenever you return the connection to the pool, its health is checked and a new one created and it is replaced if its not ok.

Hello,

JedisConnectionPool will reconnect/refresh the connection, but the application code must retry.

So your application code should:

* get the connection from the pool

* do the operations

  * in case of exception (connection lost,fail-over), 

        * catch the exception, 

        * implement the retry policy (for example)

        * get a new connection from the pool and retry 

You can find a very basic logic here:

If you are using Spring you can probably implement something with the Spring Retry library. (I have not tested it myself yet)

PS: as you can see in the link below, the fact that Jedis does not provide automatic reconnect/retry is done on purpose to keep the lin as simple as possible:
