--------------------------------------

             Summary: [TTL] Some expired data remains in memory even with eager TTL enabled
                 Key: IGNITE-12002
                 URL: https://issues.apache.org/jira/browse/IGNITE-12002
             Project: Ignite
          Issue Type: Bug
          Components: cache, general
    Affects Versions: 2.7
         Environment: Running on MacOS 10.12.6

OpenJDK 11

Ignite v2.7.0

 
            Reporter: Philippe Anes


Create an ignite client (in client mode false) and put some data (10k entries/values) to it
with very small expiration time (~20s) and TTL enabled.
Each time the thread is running it'll remove all the entries that expired, but after few attempts
this thread is not removing all the expired entries, some of them are staying in memory and
are not removed by this thread execution.
That means we got some expired data in memory, and it's something we want to avoid.

Please can you confirm that is a real issue or just misuse/configuration of my test?

Thanks for your feedback.

 

To reproduce:

Git repo: [https://github.com/panes/ignite-sample]

Run MyIgniteLoadRunnerTest.run() to reproduce the issues described on top.

(Global setup: Writing 10k entries of 64octets each with TTL 10s)
