RE: ScanQuery with predicate always returns empty result.

Actually it didn't help to get the cache with the correct types: Ignition.setClientMode(true); Ignite ignite = Ignition.start("/config/gatekeeper-token-config.xml"); ignite.active(true); IgniteCache skipCache = ignite.cache("skipCache").withKeepBinary(); ScanQuery scan2 = new ScanQuery<>((key, v

RE: Question about data distribution

AFAIU you simultaneously have about 1 million entries which correspond to 5-10 groups (measurements). Is that correct? If so, that might be the reason of the distribution that you see. Even though you have a lot of entries, you only have a few affinity mapped groups. Ignite tries keep all entries

Re: cache configuration without Key

Hello Rajesh! In Ignite, cache (and SQL table) maps not to one object but to two - key and value. Keys are unique per cache per cluster. They act as primary key in SQL and as, well, keys in cache API. So yes, you need to specify key type (or compound object) too. Regards, Ilya. -- Sent from:

Hi, 1. Please, check if index is used for field you use in order by clause. You can check this with EXPLAIN command [1]. If you see wrong index is used, then try hint [2] ignite for proper index. 2. FYI: there is limit and offset in query. For partitioned cache, Ignite will fetch 200 (limit + off

Yes - so I've been merely observing some 'unlucky' distribution if it's solely chance-based. Since the real data will consist of thousands of measurements it should be fine as it is, thanks! Best regards svonn -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/

RE: default location for ignite file db

Make sure you have persistence enabled as described at https://apacheignite.readme.io/docs/distributed-persistent-store. Also, make sure you don’t already have a custom setting for the StoragePath, WalPath or WalArchivePath. Making an environment variable visible to your process is OS-specific.

Re: horizontal scaling

Well, then it's not a horizontal scaling at all. I don't understand how do you want to achieve more throughput while all your nodes will compete for the same physical resources(CPU, network, IO). If you want horizontal scaling, you need to run all nodes on separate physical machines. Evgenii 201

Ok, then it makes sense. You cannot pass null into setIndexedTypes(). But if you don't put any @QuerySqlField annotation in value class or declare fields/indexes through Java API then no columns/indexes will be created in SQL storage. On Mon, Jan 29, 2018 at 3:59 PM, Mikael wrote: > Thanks, the
