Can JAVA API SqlQuery query a cache create by SQL DDL?

Hi guys, I use JDBC client driver to create a table,like: stmt.executeUpdate("CREATE TABLE IF NOT EXISTS person ( id int,orgId LONG, name VARCHAR, salary LONG ,PRIMARY KEY (id)) WITH \"backups=1, affinityKey=id\""); Could I use SqlQuery API to query this cache? I tried this way but does not

Best way to configure a single node embedded ignite 2.3

Hi, I have a spring boot application which runs ignite in embedded mode; the application will run in my laptop and will have a single node only. What is the best way to set this up? Thanks Sumanta -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/

Failed to find query with ID: 0

This should be super simple... Started 2 nodes from the command line, they saw each other and now show servers=2. Completely default configuration. Installed the ODBC Driver and set up a DSN. Started a C# app to open a connection and issue a create table sql statement. It fails with "Failed to

No Error/Exception on Data Loss ?

Hi, I have an Ignite cluster with 10nodes. Here is the snippet from one of the ignite server log. >>> [13:03:54] Topology snapshot [ver=11, servers=10, clients=0, CPUs=352, >>> heap=1000.0GB] Now I created a cache with mode PARTITIONED and loaded some data into the cache without

Re: Affinity Compute latency

Hi Ranjeev, Also it is possible cache.get() return value is deserialized only once on client side, but when you use EntryProcessor, entry is deserialized before EP invoke, then request result serialized before being sent back to client and then deserialized on client. Try to use get() for simple

Re: Using event to reconnect spring created cache client to server

That worked, is it a reentry issue? Should be flagged as a bug? Because reconnecting a continuous query from a disconnect event should be standard right? On 14 Nov 2017 6:35 p.m., "ezhuravlev" wrote: > Try to start a new thread and access cache from it. > > Evgenii > >

Re: Out of memory in client node freezes complete cluster

Hello! My recommendation here is to always leave some extra RAM and heap so that a hot spot won't cause OOM. Maybe use less RAM-intensive algorithms. Without stack traces and logs it's hard to say more, but OOM may not be a recoverable error with Ignite. Regards, -- Ilya Kasnacheev

Re: Inserting data into Ignite got stuck when memory is full with persistent store enabled.

Hello Ray, Have you tried to rewrite ingestion using cache API, DML or better yet DataStreamer? Because it's non-trivial to reason about problem when extra Spark layer is added. Why do you have such non-trivial amount of fields (and indices) in cache key object? Maybe try synthetic keys?

Re: Prohibit "Node is out of topology"

Lukas, what about GC pauses in your cluster? What is the max? What are network specs? Also, do you use bare metal servers or virtual machines? --Yakov

Re: Prohibit "Node is out of topology"

Hi Lukas, Several "Finished serving remote node connection" shows that the node was cut off the cluster (some socket issues) Please enable DEBUG level for logs to see more details about possible reasons (socket errors, malformed messages, etc) Thanks, Alexey -- Sent from:

Re: NullPointer in GridAffinityAssignment.initPrimaryBackupMaps

Hi Lukas, It seems that a new node is just misconfigured and it can't correctly assign partitions by Affinity Function. Please set a valid IGNITE_HOME and verify that Affinity Function [1] matches the cluster config 2017-11-11 06:10:34:973 + [main] INFO
