Does hiredis cluster support reconnect after disconnect

[qianqians]

i use hiredis cluster like this

ctx = redisClusterContextInit();
redisClusterSetOptionAddNodes(ctx, redis_url.c_str());
if (!password.empty()) {
redisClusterSetOptionPassword(ctx, password.c_str());
}
redisClusterSetOptionRouteUseSlots(ctx);
redisClusterConnect2(ctx);`

my question is redisClusterAsyncContext have redisClusterAsyncSetDisconnectCallback process dissconnect event, but redisClusterContext not have correspond method, does it means when i use redisClusterContext, it automatic processing dissconnect?

When a command is sent hiredis-cluster will first check if there is a working connection to the redis node that handles the specific key. If a previous query failed due to communication issues a reconnection attempt is performed automatically.

For the async API the callback is only used to notify the user about a disconnect, so there is no need to call a connect method here either.

Another note about your example is to make sure that redisClusterConnect2(ctx); results in REDIS_OK.
