Re: Async operations in IA C# client appear dangeroud

Hi Pavel, Thanks for the quick response. We have trialled the ContinueWith() suggestion which has resolved the issue in testing so far. I suspect this will have only a very minor performance impact. Thanks, Raymond. On Wed, Mar 10, 2021 at 10:33 PM Pavel Tupitsyn wrote: > Raymond, > > You

More heap-space. See the documentation for memory tuning: memory-tuning You might also want to check that your query is iterating over the records in your cache rather than trying to read the

Re: Using AsCacheQueryable in LINQ to access the cache

Yes, ScanQuery does not have those limitations, you can use any key and value types also there is no need to configure QueryEntity at all. However, ScanQuery can't have indexes like SQL, and always performs a full table scan which can affect performance, depending on the use case. On Wed, Mar

Re: Cluster keeps crashing with SEVERE message

We’d need to see more of the stack trace and see your configuration before this could be diagnosed. It looks like a node abruptly left the cluster. If you’re losing data it seems like you’ve not configured any backups. > On 10 Mar 2021, at 16:53, Josh Katz > wrote: > > After we load 35

I have it configured as the following: CacheConfiguration config = new CacheConfiguration(cacheName, new QueryEntity(typeof(HoldingsCacheKey), typeof(List))) Is it setup correctly for LINQ to work? Thanks, Josh From: Pavel Tupitsyn Sent: Wednesday, March 10,

Cluster keeps crashing with SEVERE message

After we load 35 million records from the database into the cluster. When we query it using a scan query we get the following SEVERE error, After that the node are restarting and the caches all show 0 keys and we have to restart the initial load. Is there a way to salvage the data so we don't

Re: Loading data to cache using a data streamer

Take a look at the data node. If the data node has restarted you might see a client disconnected exception. On Tue, Mar 9, 2021 at 1:12 PM Ilya Kasnacheev wrote: > Hello! > > Does it work with a smaller batch? My guess is that you end up consuming > too much resources and then the cluster falls

Hello! "Connection reset by peer" usually means that remote host went away or in other way could no longer serve the connection. Nothing that we can help. I'm not sure why you're getting an OOM. Maybe you're writing a very large response to some query, which causes remote client to exhaust its

Raymond, You are right, there is no efficient AND easy way to solve this. Basically, user code has to append ContinueWith to every async Ignite API call manually: await cache.GetAsync(1).ContinueWith( t => t.Result, CancellationToken.None,
