Subject [jira] [Updated] (IGNITE-12002) [TTL] Some expired data remains in memory even with eager TTL enabled
Date Mon, 22 Jul 2019 11:36:00 GMT

     [ https://issues.apache.org/jira/browse/IGNITE-12002?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Philippe Anes updated IGNITE-12002:
-----------------------------------
    Description: 
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 issue described on top.

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