Motivation
For Ignite diagnostic usually it’s helpful to get some Ignite internals information. But currently, in my opinion, there are no convenient tools for this purpose:
...
Often RDBMS for diagnostic purposes provides system views (for example, DBA_% and V$% in Oracle), which can be queried by SQL. This solution makes all internal diagnostic information available in a readable form (with all possible filters and projections) without using any other internal or external tools. My proposal is to create similar system views in Ignite.
Description
Aleksey Plekhanov implemented working prototype (PR:[1]). It contains views:
...
SELECT cm.NODE_ID, cm.CACHE_PUTS FROM INFORMATION_SCHEMA.IGNITE_CACHE_NODE_METRICS cm
WHERE cm.CACHE_NAME = 'cache'
ORDER BY cm.CACHE_PUTS DESC
LIMIT 5
