Hi,
cache.containsKey() never locking key (I checked it in Ignite version 1.7
till 2.0), but you can use simple cache.get().
This method (cache.get) will got a lock for particular key, even if returns
null.

Hi all,
I've recently upgraded to Ignite 2.0 and noticed that
IgniteCache.containsKey no longer acquiring a transaction lock on the passed
key. In my experience, it seemed to be the case in ignite 1.8 & 1.9.
(Correct me if I'm wrong, I assume a containsKey is considered as a READ
cache operation)
