Re: Cache refresh from persistent store question

Hi Satya, The main problem here is that Ignite is completely abstracted from the persistence store by CacheStore interface. It can be any storage - relational database, disk based key-value storage, MongoDB, HDFS, etc... The implementation of such trigger will be different for different stores,

Re: Can I set an expiry policy for some specify entry?

Hi Vladimir, Thank you for your help. I have tested your test case, but it was not worked. It is failed as the got cache1 is null. Here is the output result and exception, [09:23:09,404][INFO ][test-runner][GridDiscoveryManager] Topology snapshot [ver=1, servers=1, clients=0, CPUs=8,

What I mean by isolation is that they do not try to automatically discover each other. They only form a cluster manually when triggered. > Am 01.12.2015 um 13:58 schrieb Denis Magda : > > fsapei, > > What do you mean under isolation between two different caches? > All the

Re: Can I set an expiry policy for some specify entry?

Hi all, We can easily set an expiry policy for any entry. Sorry to Anton and Vladimir , you are right. Talk is cheap, show you the code... the test case public static void testPut1() throws Exception { getCache().put("key","val", TimeUnit.SECONDS.toMillis(1)); String val =

Re: Continuous update Data Grid Cache

Thank you for your idea. Your solution should work. May it be possible to perform the following operation? - Create a new cache and isolate it from being replicated with the old cache. - Populate data on new cache - Shutdown old cache and remove the new cache isolation. fsapei > Am 30.11.2015

Re: Could not get any response from SQL Query

Hi Denis, my scenario is as follows: - start a node server with the following configuration: JVM_OPTS="$JVM_OPTS -Xms4g -Xmx4g" JVM_OPTS="$JVM_OPTS -XX:+UseParNewGC -XX:+UseConcMarkSweepGC -XX:+UseTLAB -XX:NewSize=128m -XX:MaxNewSize=128m" JVM_OPTS="$JVM_OPTS -XX:MaxTenuringThreshold=0

Re: Continuous update Data Grid Cache

fsapei, What do you mean under isolation between two different caches? All the caches live they own life and don't affect each other. -- Denis On 12/1/2015 12:08 PM, Ferry Syafei Sapei wrote: Thank you for your idea. Your solution should work. May it be possible to perform the following

Re: Could not get any response from SQL Query

Fsapei, Seems that the cluster breaks down when you execute the queries over 40 million rows. As a result you see partition map exchange related exceptions. Share the full logs using some file-sharing service. Analyze your SQL query by paying attention to the following: - What query do you

Re: Cache refresh from persistent store question

Hi Val, I realize this is not a trivial task but here are a couple of ideas. 1. Triggers that run an offline task outside of the database processes (perhaps an ignite instance) that sync the cache. Depending on the database, we could auto-generate the DDL for defining the trigger making it easier

Re: Can I set an expiry policy for some specify entry?

Lin, As you can see at example you can use cache.withExpiryPolicy() to gain cache wrapper with specific ExpiryPolicy. This policy will be used during operations on this cache wrapper, only. You can create as much wrappers as you need and put/get/etc entries using them. I recomend you to use
