Maxim, You're right that the system cache is still likely to be used by plugins. We at GridGain use it for security features, for example. As far as I know, that's not the only case.
I also agree that the metastorage should be the preferred way for this kind of purposes, but is there any harm in keeping the system cache for now? Unlike the legacy Service Grid, this is not a public feature that can be used directly by a regular user, so I'm not sure why the rush. How about we instead deprecate the system cache, clearly document how to use the metastorage as an alternative, and then complete the removal sometime in the future? -Val On Sun, Nov 28, 2021 at 6:49 AM Maxim Muzafarov <mmu...@apache.org> wrote: > Igniters, > > > Since the legacy service grid implementation was removed [2] I'd like > to remove the ignite-sys-cache also.
