Hi! Ignite iterates over the whole keys collection, then performs a remove(keys) method. So if there are a lot of items and a distributed cluster, then this would take a long time.
You can take a look into into regular IgniteCache, which has a destroy() method. And use put/get for insert/check operations. -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/
