Re: deploy is not working by IgniteDataStreamer

Oh great thanks! I'm working so now. I just thought that IgniteDataStreamer.deployClass can help me in this case. It's a little strange because if I want to handle the Call.class on the nodes but want to save another object in the cache and I have to implement the special binary mapper for both

Can you also share your configuration file? By the way, using double as a key type seems to be a *really* bad idea. It should not affect performance, but may cause a lot of issues. Best Regards, Igor On Tue, Jun 27, 2017 at 4:46 PM, Rahul.S wrote: > this is the function

Re: Scanquery and Peer classloading

Hi Helge, The problem is that the filter passed to the ScanQuery is executed on the server nodes as is and since these nodes have DynaFormModel class only in binary form they are not able to operate on it directly from the code. Hence you need to pass a filter which will operate on BinaryObjects

Well, if you perform DML operations with single row by query, then the reason may be a network round trip - for every operation you need to send packet and receive response, which may cause network delay. Best Regards, Igor On Tue, Jun 27, 2017 at 3:10 PM, Rahul.S wrote: >
