Re: High availability of local listeners for ContinuousQuery or Events

Hi, It's true that currently you need to implement something for Continuous Queries failover in your application code. Continuous Queries have setInitialQuery API to help with that. How it's supposed to work is: you define an initial query (e.g. an SQL query) which fetches the data that's

XML Configuration issues

Hi, I'm trying to change the xml configuration in apache ignite to support SQL for data caches: see https://pastebin.com/4qtepp0A However this config file doesn't seem to work. If I comment out the cache configuration part it works. What's wrong with it? Can't I mix cache configuration and

Re: Ignite Client Node OOM Issue

Hi, SQL query may be potential cause of the OOM. Please check that: 1. Simple scan+filter queries (e.g. SELECT * FROM WHERE ) that may produce big results run in lazy mode (SqlFieldsQuery#setLazy); 2. Queries that requires not indexing sort or group aggregates don't produce  big result set

Adding fields without adding to sql table DDL

Hi, we define our caches via a create table statement, and specify our various columns/fields. We would like to add some additional fields, that are not exposed as part of the DDL, so not visible in a select statement. Is this possible? If I try and get a BinaryObjectBuilder for my type, and add

Re: Large Heap with lots of BinaryMetaDataHolders

Hi, there are approx 6 server nodes, and only around 10 client nodes at the moment (there will eventually be several hundred client nodes once this is enabled in production if we can overcome these issues - and the cluster metric messages which are causing over 1mb of allocations per sec). Each

Re: Possible memory leak in Ignite 2.9

Hello! I think this is expected. Ignite needs to convert an entry (800G array) into packets to send to other nodes or put to persistence, where it will allocate another array (800G more). I don't think you can do anything here, short of chunking your data. Regards, -- Ilya Kasnacheev пт, 13

Re: SQL and Key Value usage in C++

Hello! The key_type and value_type are names of classes which may be put and get in this cache once you configure serialization properly. You can use INSERT/Put and SELECT/Get in any combinations. Please see https://ignite.apache.org/docs/latest/cpp-specific/cpp-serialization as an example. You

Re: Proper shutdown from C++ environment

You would only get SIGINT if you run your application in a shell and ctrl-c it right? Can you not 'wait' on a key press and stop ignite properly instead? I looked at the same issue recently and I wouldn't expect ignite to do anything that isn't documented - even if it does it now, it may not do

Proper shutdown from C++ environment

Re: IgniteC++ throughput

Why are you using index type FULLTEXT for a Long data type? That should be SORTED I think. As I said - I used the example shipped with ignite as a starting point. I changed it to SORTED and it looks better indeed. Scenario 4 now runs at about 7K TPS. -- Sent from:
