Hello, finally I did the following trick.

I broadcast my select request on each node, executing the select with Lazy and 
collocated, then I user QueryCursor and create BinaryObjects that I insert into 
cache by 5000 packet.

Wich seems to be good enough.

Thanks for your help.

It's an insert into select. We made "meta" tables to allow doing other selects.

Or can I do a lazy select then batch insert you mean ?

Hello!

I think it would make better sense to mark already updated entries, update in 
batches until no unmarked entries left.

Hmmm. Can I use limit and offset ?

Doing limit 10000 by example and continue while insert  ount = 10000 ???

Hello!

I'm afraid you will have to split this query into smaller ones. Ignite doesn't 
really have lazy insert ... select, so the result set will have to be held in 
heap for some time.

Hello,  we have 6 nodes configured with 3Gb heap, 30Gb offheap.

We store lot's of data in some partitioned tables, then we are executing some 
"insert into select... join..." using SqlQueryField (or SqlQueryFieldEx).

With tables of 5000 000 lines, we ran in a OOM error, even with lazy set to 
true and skipOnReduceTable.

How can we handle this please ?

Regards.
