Hello,
below, I attached some exception that I get during querying by JDBC client.
It occurs for SELECT * COUNT.
It is very important that this exception occurs about once every three times
- twice getting the correct result.
My cache has exactly 3000000 entries.
java.sql.SQLException: Failed to query Ignite.
