Subject [jira] [Created] (IGNITE-12334) Throttle getAll operations on the grid
Date Mon, 28 Oct 2019 19:35:00 GMT
ABHISHEK SHUBH GUPTA created IGNITE-12334:
---------------------------------------------

             Summary: Throttle getAll operations on the grid
                 Key: IGNITE-12334
                 URL: https://issues.apache.org/jira/browse/IGNITE-12334
             Project: Ignite
          Issue Type: Improvement
    Affects Versions: 2.7.5
            Reporter: ABHISHEK SHUBH GUPTA


Per [this thread|http://apache-ignite-users.70518.x6.nabble.com/Throttling-getAll-tt29956.html],
in a situation where a large number of keys are requested using getAll and/or the value objects
are large, there is a worry about GC issues/humongous objects/OOM on the grid. It would,
therefore, be beneficial to the stability of the product if there was throttling available
on the ignition nodes when clients do large getAll operations.  

The throttling could perhaps be based on the number of keys passed on to getAll. If it exceeds
threshold it could reject the request or optionally, auto-create multiple smaller batches.
