Re: Cron job

Actually, IgniteScheduler API is still available [1]. I tend to agree that it's not very useful, but it's definitely not dumped :) [1] https://github.com/apache/ignite/blob/master/modules/core/src/main/java/org/apache/ignite/IgniteScheduler.java -Val -- View this message in context: http://ap

Re: Cron job

Hi Dmitriy, Thank a lot for your tip. Does Ignite provide any built-in mechanism to periodically execute a task on grid nodes or I can simply use a Java ScheduledExecutorService or even a Timer class? Cheers, Paolo On Wed, Jan 20, 2016 at 8:53 PM, Dmitriy Setrakyan wrote: > Hi Paolo, > > You

Re: Cron job

Hi Paolo, You can definitely deploy a cron task that will periodically execute a task on top of Ignite. However, node attributes are static and get assigned on startup, so I don’t think you will be able to change them. Instead, I would suggest to create a small cache using node ID as a key and at

Cron job

Hi there, Is there a way to deploy a cron task in each grid node and periodically set an attribute in the ClusterNode structure? Any suggestion? Thanks a lot Paolo

Re: TcpDiscoveryVmIpFinder's isShared property

Yakov, I am reading this S3 use case for the 2nd time and still cannot understand it. I think, this is one of the reason why this property has caused so much confusion. I vote to use it only for local VM and property renaming it. D. On Tue, Jan 19, 2016 at 11:45 PM, Yakov Zhdanov wrote: > I qu

Re: UnsupportedOperationException on adding indexed types to a config object

Hi, Thanks for catching this. There was a tiny issue that is reproduced only when a CacheConfiguration is being initialized like in your example. I've done a hot fix and pushed changes into the master. On your side you can initialized the configuration the way below to avoid the exception Cache

Re: Runtime error at IgniteSpiThread

Hi, As far as I remember Ignite community fixed a lot of issues related to the stability of TCP discovery SPI in version 1.5.0. The one you face should be fixed as well. So please upgrade to version 1.5.0 and check you app with it. 1. Is there any restriction on the number of clients which can b

Hi, This is a generic log from a node that detected that another one node left a cluster abruptly. I need all the logs from all the nodes you have. Please share them via Dropbox or some other file sharing tool. In general a node can leave topology because of long garbage collection pauses. So ac

Re: Ignite stream processing

Hi Jack, Probably you can rely on streaming sliding windows [1] if you don't need to have all the data in the cache. How do you process the data? What kind of queries do you use? Finally, please properly subscribe to the user list (this way we will not have to manually approve your emails). All

Re: Grouping cache when loading data using CacheStore

HI, CacheLoadOnlyStoreAdapter [1] perfectly fits for your cause it was deliberately designed for the cases when fast loading from raw files, CSV or other resources is needed. Unfortunately there is no an example in Ignite that shows how to use this adapter for now. I've created a ticket to be sur

Re: Grouping cache when loading data using CacheStore

Importing the CSV into H2 database will require a huge amount of memory, since the file is big and contains a lot of redundant data. Some rows should be aggregated since they belong to an object with the same key (e.g. accountNumber). Moreover the rows are not sorted by the accountNumber. Coul
