Failed to acknowledge TcpDiscoveryClientMetricsUpdateMessage

[Calvin KL Wong, CLSA]

Hi,

I am getting the error below from my client node.
It couldn't get an ack for a TcpDiscoveryClientMetricsUpdateMessage it sent out.

Can you please let me know the nature of this 
TcpDiscoveryClientMetricsUpdateMessage message?

-  The main question is why did this happen?

-  Who is responsible for acknowledging this message?

-  Is 'id' my own nodeId?

Re: .NET - Complex LINQ queries support

[Pavel Tupitsyn]

Roman,

Thanks for the reproducer. I needed that to better understand the issue.

And, I'm afraid, we won't have support for this kind of queries anytime
soon.
Even Entity Framework does not support this kind of grouping.
