Apache Ignite Workshop: Developing Applications That Are Easy to Manage
Igniters, FYI: next Wednesday, December 9 2020 at 21:00 UTC+3 I am giving an Apache Ignite Workshop "Developing Applications That Are Easy to Manage". Use this link to register: https://www.gridgain.com/resources/webinars/apache-ignite-workshop-developing-applications-are-easy-manage Abstract Typically, operations exceed fifty percent of the cost of an IT system’s life cycle. By developing applications that can be easily managed, developers can significantly reduce the cost of ownership. Manageability is especially important for distributed applications because they are especially complex and often mission-critical. In this webinar, we discuss the following topics: - Methods for using Apache Ignite to develop manageable applications - The monitoring and managing tools that Ignite provides - Use cases that use popular third-party tools to monitor Ignite -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/
Re: ThinClient issues
Hi, use: https://ignite.apache.org/releases/latest/javadoc/org/apache/ignite/configuration/IgniteConfiguration.html#setConsistentId-java.io.Serializable- to set the consistent id. Thanks, Alex -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/
Re: ThinClient issues
Finally found the issue. In the thin client configuration I had only one port provided to connect to the server nodes. As soon as I provided the default range (10800-10900) the connections seemed to behave better. This resolved the issue somehow. However I tried it out at the cluster on the campus. With 50 nodes as thin clients connecting to two server nodes the server nodes seem to be completely overwhelmed. Then I thought why not let every node have it's own Ignite instance. It seems that a lot of resources are consumed from the Ignite Servers on the nodes even why no load at all on requests. Then I realized that starting up all servers is a nightmare. It takes several minutes and just activating all nodes is more than 3 minutes without even reliably bringing up all of the nodes Does anybody know how to define the consistend-id's in the xml file?

Re: C# CacheStoreAdapter - Customizing Load, LoadCache methods
Thank you for the clarification! For this use case where data is being pulled from an underlying RDBMS and instantiated as an Associate object, is it possible to work the Associate object as a Binary Object similar to what you've done here? Also, I see than in Vladamir's loading example, he uses the Colocation by Partition, but that API is not available for C#. Is it possible to speed up loading cache by using Binary Object + Colocating by Key, or Binary Object + MapReduce API? -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/
