Re: loadAll and removeAll from cache with custom store

For the removeAll() call, I do see that after I do a loadCache((k,v) -> true) I can delete items from the store, but my store's deleteAll() only ever gets 1k items once, deletes them from the store, and then is never called again to delete the rest of the items in the store. -- Sent from:

loadAll and removeAll from cache with custom store

Hi, For loading all data into Ignite before running a job, is loadAll sufficient? How can I prevent running loadAll on subsequent job runs? Is there a way to control whether or not the cache is loaded from the read-through store if the data has already been loaded? I'm concerned about job startup

Re: Performance comparisons

"makes sense to run benchmarks" and "makes sense to force everyone to run their own" aren't the same. I think you support the first, whereas I argue with the second. Nearly everyone publishes numbers vs Cassandra which makes it easy to compare tuned setups of any two products (except Cassandra

Re: IgniteVisor showing the cache, but SQLLINE tables are not seen

The first approach, as I mentioned above, is using DDL. Please see an example https://github.com/apache/ignite/blob/master/examples/src/main/java/org/apache/ignite/examples/datagrid/CacheQueryDdlExample.java The second one, you need to use CacheConfiguration.setIndexedTypes() as follows:

Sure, I meant you need to create your own inner class: private static class WorkflowEntryProcessor extends EntryProcessor { @Override public Object process(MutableEntry entry, Object... arguments) throws EntryProcessorException {

Re: Ignite cluster configure (2.3.0)

Hi Dmitriy, 1. You may use node filter [1] and specifically org.apache.ignite.util.AttributeNodeFilter that could be configured in XML without writing code. 2. Yes you can. You need to configure data regions and set persistenceEnabled flag. After that you may apply cachesh to that regions. [2]

Re: List of running Continuous queries or CacheEntryListener per cache or node

Hello, Dmitry. I think it a great idea. Do we a feature to list all running ComputeTasks? I, personally, think we have to implement possibility to track all user-provided tasks - CacheListener, ContinuousQuery, ComputeTasks, etc. В Чт, 21/12/2017 в 10:13 +0300, Dmitry Karachentsev пишет: >
