how can I delete shutdownhook add by ignite?

I start ignite instance by "Ignition.start("ignite.xml")" in my server, but I want to control the stopping process(press ctrl+c) myself, for example: private static void waitForShutdownCommand() { Thread shutdown = new Thread() { public void run() { try {

We are running Ignite 1.8.0 within Docker on an AWS instance. Ignite registers with Zookeeper. We use a BasicAddressResolver in the Ignite config so that only the Docker host IP is registered. This works fine until the tcp-disco-ip-finder-cleaner thread kicks in and adds the loopback and the

XMX/XMS for embedded ignite in client mode

Hello all, I'd appreciate your advice on the following issue, that I have had for some time: When connecting to an existing ignite cluster in client mode, I get the warning "Initial heap size is 504MB (should be no less than 512MB, use -Xms512m -Xmx512m)." and I was wondering how to

Re: Basic question on scaling of reads with ignite sql queries

Thanks Andrew for the explanation. Just one additional question. Lets say i have an apache ignite cluster running on 2 different machines, and we give noOfBackups of a replicated cache as 1, each of the 2 machines will hold 1/2 of the primary partitions and 1/2 of the backup partition.

Re: Basic question on scaling of reads with ignite sql queries

Hi Tuco, Seems, there is a misunderstanding. Ignite does not have master and slave nodes. All nodes are equals. There are primary and backup partitions distributed among grid nodes. SQL queries are running on index of primary partitions on all data nodes. Actually, index contains backup data,

Re: Input data is no significant change in multi-threading

Hi Woo, It may be reasonable, if you see, nodes resources utilization is too low and rising per-node-buffer size have no effect (that means you prepare data for nodes too slow). Of course, you should check first if network isn't a bottleneck. On Tue, Apr 25, 2017 at 10:08 AM, woo charles

Re: Basic question on scaling of reads with ignite sql queries

Hi Tuco, Backup partition is full copy of primary partition, so you will run sql query on same data. There is no need to run query on backups as we can run in on primaries in multiple thread with same effect. We already test approach with running query in multiple threads when every thread works

Re: Basic question on scaling of reads with ignite sql queries

If SQL queries would execute not only on all masters, but on at least one instances from (M1,S11,S12)+(M2,S21,S22)+(M3,S31,S32), then the reads could be scaled linearly by increasing the no of slaves. ie a query would execute not on all masters, but on any combination of nodes where complete data
