 It depends on what kind of information are you interested in. For sample, you can use the Cluster API to inspect a node’s metrics manually [1].Or take a look at some monitoring tools, like WebConsole [2]. [1] -

When we create a new table via SQL, it creates the cache for the table (as expected). However, if we drop the table, the cache is not deleted. We can't figure out how to delete the cache. So, we have many caches accumulating that we can't delete but can't use for SQL because we've deleted their

Have you tried a cache template [1]? After you designed your custom affinity function, you can configure it for a new cache template.You could use it with the CREATE TABLE statement [2].Please, note, that a template should be registered in advance. [1] -

Hi! If each row is stored as an entry in the cache you can expect an overhead of around 200 byte per entry, so 200MB just for the actual entries (1M) not counting your data (more if you have any index). You can control the streamer, how much data and when it should be flushed, I have no

Hello! Since we're in 2019, we don't recommend running any Ignite nodes with -Xmx2G (that is, 2 gigabytes of heap allowance). It is certainly possible to run Ignite with less heap, but the reasoning of such is not very clear. Please also note that our JDBC thin driver supports streaming, and it
