---------------------------------------------
Hey Alper,
Sure, will take a look during next few days.
> Disable EventStorageSpi by default
> ----------------------------------
>
> Key: IGNITE-4812
> URL: https://issues.apache.org/jira/browse/IGNITE-4812
> Project: Ignite
> Issue Type: Bug
> Components: general
> Affects Versions: 1.9
> Reporter: Valentin Kulichenko
> Assignee: Alper Tekinalp
> Fix For: 2.0
>
>
> Current default implementation of {{EventStorageSpi}} is
> {{MemoryEventStorageSpi}}. It consumes a lot of memory, while is used only
> for events querying (i.e. not listening), which is a fairly rare use case.
> Need to:
> * Introduce {{NoOpEventStorageSpi}}.
> * Make {{NoOpEventStorageSpi}} the default one.
> * Throw an exception when {{IgniteEvents#localQuery}} or {{#remoteQuery}}
> method is called with default setting. Exception message should explain how
> to fix it.
