about connection pool

[paladin4409]

I have a test for lettuce connection pool, start 500 threads run like this:

public void run() {
            Thread.currentThread().setName("thread_" + i);
            while (true) {
                String str = RedisDataFunc.getForString("key1"); // _use string redis template to get value_
                log.info("str: " + str);
            }
}

I set the lettuce pool configuration like this:

spring.redis.timeout=3
spring.redis.lettuce.pool.max-active=200
spring.redis.lettuce.pool.max-idle=100
spring.redis.lettuce.pool.min-idle=10
spring.redis.lettuce.pool.max-wait=10000
spring.redis.lettuce.cluster.refresh.adaptive=true
spring.redis.lettuce.cluster.refresh.period=10000
spring.redis.lettuce.pool.time-between-eviction-runs=10000
spring.redis.lettuce.shutdown-timeout=10000

and I set ShareNativeConnection = false.

I hope there will be 200 connections for redis, because there are 500 threads, 500 is more than max-active=200, so every connection will be busy! and I think these 200 connections will be long connection. But actually , the test app only keep 100 connections for redis, and the 100 connections are not long life connection, they frequently open / close sockets, there are lots of TIME_WAIT sockets on test app computer. my question:

1. after set ShareNativeConnection = false, every socket only for an operation? I mean one thread of the 500 threads do "get("key1")" one time, lettuce will open and close a socket for it?
2. when lettuce closes socket? I set time-between-eviction-runs=10000, but it seems not work, because it check idle socket and close it for every operation instead check the idle sockets ervey 10s.

My English is poor, but hope your suggestions, thank you.
