Re: How does CacheStore persistence actually work?

Hi, 1. Ignite doesn't cate about whether persistence operations are local or not. It fully relies on CacheStore implementation. 2. CacheStore classes should be in classpath on all nodes including client nodes. These classes are not delivered automatically. 3. Writing to store always happened on pr

CodecNotFoundException: [smallint <-> java.lang.Integer] with Cassandra

RE: Provide persistence settings inline for Cassandra KeyValuePersistenceSettings?

Thanks, Evgenii. A minor addition, the content needs to be CDATA, as the value element is of string type and does not allow nested content. Roger -Original Message- From: ezhuravlev [mailto:e.zhuravlev...@gmail.com] Sent: Thursday, July 13, 201

Re: Security in Ignite

Hello, As Val told Apache Ignite doesn’t provide any security related functionality at the moment but rather some interfaces you can implement on your own. To get the security support you need to look at commercial products built on top of Ignite: https://docs.gridgain.com/docs/security-and-au

Re: Execute Custom function in H2 Console

Hi, If you have defined a custom function according to the https://apacheignite.readme.io/docs/miscellaneous-features#section-custom-sql-functions then to use it from H2 console you need to prefix it with the schema name of the cache where you have registered your function, for example: *SELECT YO

Hello, Sorry to reply to this old thread but being a data fabric and the most popular being data grid and data needs security in the first place, it would give a great boost if some basic plugin/security code is already provided to hook up quickly to an ldap server or DB. I was doing a POC on Igni

Re: Ignite DataStream Troughput

Hi Mimmo, I think you should play with the following streamer parameters: public int perNodeBufferSize() public void perNodeParallelOperations(int parallelOps) dataStream has a buffer per Node, perNodeBufferSize defines how many items should be saved in buffer before send it to server node.

Hi Lucky, It is a bad practice to set JVM memory >= 32GB. Usually, you can get a performance degradation for heap > 10Gb due to heavy GC. Also it make no sense to have different Xms and Xmx params on server side as, JVM never revert back free memory to OS. >From ignite-2.x there is no need to hav

Here you use same cache object from all computes. >> cache.query(qry.setArgs(args.toArray()).setLocal(true)).getAll(); So, actually, you run query on same cache node from threads belongs to other nodes. This will not work in multi JVM env. Just keep in mind that your task\job object can be tran

Hi, I don't quite understand your case, but with LEFT JOIN you will have results even if there is no matching id in B, that's why "FROM A.R as r LEFT JOIN B.I as T ON r.id = T.id" works. By default cross cache join will operate only on data available locally on each particular node. Probably th
