Java – jedis – when to use returnbrokenresource()

When we should use this method In jedisconnectionexception, jedisdataexception or any jedisexception For jedis, my knowledge doesn't have a good API document

try {
    Jedis jedis = JedisFactory.getInstance();
    Pipeline pipe = jedis.pipelined();
    Response<Set<Tuple>> idWithscore = pipe.zrangeWithscores(cachekey,from,to);
    **// some statement which may cause some other exception**
    Response<String> val = pipe.get(somekey);
    pipe.exec();
    pipe.sync();
}catch (JedisConnectionException e) {
    JedisFactory.returnBrokenResource(jedis);
}catch(Exception e){
    **// What API I should use here?,how to find whether to use returnBrokenResource(jedis) or returnResource(jedis)**
}finally{
    JedisFactory.returnResource(jedis);
}

Solution

Returnbrokenresource should be used when the state of an object is not recoverable The jedis object represents the connection with redis It becomes unavailable when the physical connection is disconnected or the synchronization between the client and the server is lost

Using jedis, these errors are represented by jedisconnectionexception So I will use the exception returnbrokenresource instead of others

Jedisdataexception is related to bad usage of jedis API or redis error on server side

Jedisexception is for everything else (usually after lower level errors, independent of jedis)
