Retry configuration for Redis/Jedis in Sentinel mode

[anil181]

We have a multi-threaded java job which is used for reading data from RDBMS DB and writing the data into the Redis server.
We are having a Sentinel setup to have the HA mode of Redis (6.2.3), and using Jedis 3.6.0 to connect from the application job to Redis.

We have a scenario where the job is in progress and master goes down and during the master failover the job fails with the error as below for some of the threads while doing the data refresh:

Caused by: java.net.SocketException: Connection reset

Could you please suggest if there is any retry configuration in the Jedis using which it can retry before throwing exception to Application?

Thanks & Regards,
Anil

@anil181 Sorry, retry is not supported for Sentinel at this moment.

@sazzad16, thank you for the prompt response 👍 . Is it planned for future release or any timeline for availability for this ?

@anil181 You're the first person to ask for it (as far as I can remember). And there's no PR for it. So it'd take quite some time to introduce this feature.

Jedis is a community driven project and we'll definitely welcome and look into it if you (or your team) can craft a PR.
