Hi David, When you call getAll(), you fetch the whole result set to the client. If you're doing 'select *' from a disctributed without any conditions, you will very likely get an out of memory, because to execute such a query your client needs to have capacity equal to the total capacity of all servers.
First of all, I would recommend to avoid such queries. You should always try to minimize network traffic and sending the whole cache to the client is obviously a bad idea from this standpoint. Second of all, if the result set is still large, you'd better iterate through the QueryCursor instead of calling getAll(). If you iterate, Ignite will fetch data in pages, discarding old ones. So the client will have only one page at a time in memory and will not fail. -Val -- View this message in context: http://apache-ignite-users.70518.x6.nabble.com/Failed-to-run-reduce-query-locally-tp6667p6678.html Sent from the Apache Ignite Users mailing list archive at Nabble.com.
