Hi Sergey, There could not be an exact answer to your question. It depends mostly on your use-case.
1. first of all, you should look at CPU/mem/network usage 2. and then you should check SQL debugging guide, starting from EXPLAIN for your query. Please see [1] for details. 3. you could enable dataRegionMetrics and dataStorageMetrics as it described at [2] and compare values with small/huge load/data capacity 4. you could also enable Cache metrics [3] [1] https://apacheignite-sql.readme.io/docs/performance-and-debugging [2] https://apacheignite.readme.io/docs/memory-metrics [3] https://apacheignite.readme.io/docs/cache-metrics Thank you, Alexey -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/
