Hi Val, Thank you for your response. I have created https://issues.apache.org/jira/browse/IGNITE-7482. Unfortunately, the solution does not seem to be resolvable with simple local patch - hence could not propose solution. But will try to take a closer look next week.
For time being I went into direction of implementing IndexingSpi based on Lucene which solves nicely the performance problem but brings another question, which I shall post in another thread. Regards, zbyszek -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/
