How to make full use of network bandwidth?

Hi, I have two physical hosts, each host has a sever node, node A and node B. I created a table and inserted data into table via JDBCthin driver. But the performance of inserting is poor. When the bandwidth of network is 100Mbps, the throughput from node A to node B is only about 2Mbps, 1 million r

Re: Connection problem between client and server

Hi Denis, Thanks for the analysis. Today we tried to reduce the Java class path(.../lib/*) when start a server node, but it still sends all the jar files(absolute path) to client. and we also find that, it looks like client node sends its info(path...) to server node, and then server node sends

Re: java.lang.IllegalStateException: Cache has been closed:

Hi Rajarshi! Well, it must be, that you are actually closing the cache. Check, that you didn't put cache creation into a try-with-resources. When *IgniteCache.close()* is called, then cache is destroyed. Denis чт, 4 янв. 2018 г. в 18:17, Rajarshi Pain : > Hi, > > I am using Ignite 2.3 for my ap

Re: off heap memory usage

Hi! Looks like this metric shows only non-heap memory, consumed by JVM itself. Looks like a bug. If you want to get a picture of how much memory Ignite pages consumed, you can get *DataRegionMetrics#PhysicalMemoryPages* and multiply it by a size of a data page. To do this you should enable memory

Re: H2 console - GridH2QueryContext is not initialized

Hi Rajarshi, I was able to reproduce the issue. It seems that using CacheConfiguration#QueryParallelism greater than 1 may lead to this behavior. I will investigate this use case further (will create a JIRA ticket for that bug). Thanks! -- Sent from: http://apache-ignite-users.70518.x6.nabble.

dotnet thin client - multiple hosts?

IgniteClientConfiguration.Host is currently a string property that appears to accept a single dotted IP address, or single host name. However, in the event that the single configured host/node goes offline, it would be useful if the client would attempt to dynamically connect to one or more additi

Re: Connection problem between client and server

Jeff, Your have indeed a lot of data sent over discovery. Almost all of it is taken by node attributes. Try reducing Java classpath and PATH environment variable. Also increasing of TCP window could help, because now a lot of small messages are sent instead of a few big ones. Cross-sending it to
