Re: How to save odd number objects on one node and even number objects on another node

Hi Rishi, Yes, you can do this by implementing your own AffinityFunction and then add it to CacheConfiguration with CacheConfigucation.setAffinity(..) method. On Fri, Dec 16, 2016 at 12:34 AM, rishireddy.bokka < rishireddy.bo...@gmail.com> wrote: > Hi Ignite Team, > I recently started using Igni

Re: Detecting terminal condition for group of items in Ignite cache.

In case the performance of a fix rate is appropriate for you I think your solution make sense because it is very simple and robust. Also, you can use IgniteScheduler ( https://ignite.apache.org/releases/mobile/org/apache/ignite/IgniteScheduler.html) instead of spring scheduler. On Wed, Dec 14, 20

Vladislav, Actually I don't know the exact object that causes the deserialization problem. For me it looks like a remote call fails. If I have to use some workaround, I prefer switching off the compact footers. Dmitry. -- View this message in context: http://apache-ignite-users.70518.x6.nabbl

Binary Marshalling issue

Hi, I have an application which uses apache ignite cache in an embedded mode. On each GC cycle, I am seeing lot of memory getting retained. Cache has around 10K entries and each entry is an object containing a map of 500 entries. The key and value in the map within an object is string of less t

I think, simplest AffinityKeyMapper[1] will be sufficient: public Object affinityKey(Object key) { if (key instanceof Integer) return ((Integer)key) % 2; } and configuration like this: ... [1]: org.apache.ignite.cache.affinity.AffinityKeyMapper

Hi As I understand you have many short-lived Maps as values in cache. Yes, in your case, you can get a lot of garbage due to Map will be marshal\unmarshal along with each of its content at every cache entry access. On Fri, Dec 16, 2016 at 4:26 PM, Pradeep Badiger wrote: > Hi, > > > > I have an

Hi! In your case key and value classes are not deployed on server nodes. You need to deploy classes on all nodes or to use IgniteCache.withKeepBinary. Also you don't need to implement visitUsingMapKeysToNodes methods. You can use IgniteCompute#affinityRun or IgniteCompute#affinityCall methods. The

Hi, @QuerySqlField is annotation for Ignite SQL [1], it has nothing to do with Cassandra integration. To specify column name which differs from Java field name, you should use 'field' tags inside 'valuePersistence', like shown in the example [2]. [1] https://apacheignite.readme.io/v1.8/docs/index

Re: 答复: 答复: 答复: query binaryobject cache in zeppelin

This happens because Ignite adds predefined _key and _val fields to every table. They represent whole key and value objects and deserialize on the client when you select them. Now they are also selected when you do 'select *'. This will improved in future, but for now you should avoid doing this an
