JedisPooled vs JedisPool

[Oscar Besga]

Hi

I'm with my JedisExtraUtils project (https://github.com/oscar-besga-panel/JedisExtraUtils) and I use JedisPool in my classes.

I'm considering migrating it from JedisPool to JedisPooled (new kid on the code)

For what I see, JedisPooled uses internally the try-catch-resources; so for individual redis calls can be better to have less boilerplate code.

But if you use more than one redis call, it migth be better to use the classic try-with-resources and use the  same connection object to the sequential calls.

Is my understanding correct ?

Is there a way to convert a JedisPool into a JedisPooled and/or viceversa (using the same connections and connection pool under the hood)

What do you this of this code

Code

default void withJedisPoolDo(Consumer<Jedis> consumer) {
    try (Connection connection = getJedisPooled().getPool().getResource()) {
        consumer.accept(new Jedis(connection));
    }
}

Example

void example() {
    withJedisPoolDo(jedis -> {
        String s = jedis.get("my:key:001");
        s = s + "example";
        jedis.set("my:key:001", s);
        jedis.expire("my:key:001", 3000);
    });
}

Thanks

Not really. You won't save anything in terms of network round trip.

To optimize with sequential calls, you'll need pipelining.

No.

Hi !

I've limited the helper to the JedisPool class

as it has no to litlle sense in JedisPooled

Take a look when you can
