Querying over fields in the object inside Cache value

Hi, Is is possible to query (Scan, Sql etc) cache on the fields inside object in the Cache value? For example : Employee has a Address Address has fields like Street, Zip code, City Cache Key : Emp Id Cache Value : Employee Is it possible to Index or Query on field "City" in the above scenario?

Re: NullPointerException on ScanQuery

Hi all. It seems one method uses affinity: cctx.affinity().primaryPartitions(n.id(), topologyVersion()); other uses topology API. cctx.topology().owners(part, topVer) Are these two fully consistent? On Tue, Dec 6, 2016 at 4:58 PM, Alper Tekinalp wrote: > Hi all. > > We have 2 servers and a

Re: Querying over fields in the object inside Cache value

Yes, this is possible. If you have QuerySqlField annotation on Employee.address and the same annotation on Address.city, then the field CITY must be available for SQL queries. Sergi 2016-12-07 11:04 GMT+03:00 Gaurav Bajaj : > Hi, > > Is is possible to query (Scan, Sql etc) cache on the fields i

Re: Querying over fields in the object inside Cache value

Great. Thanks for prompt reply. What is the way to indicate same via configuration? For example, for Address it will be as per below, but not sure how to do it for City.

Yes, in QueryEntity you have to define it using a dot notation. Sergi 2016-12-07 12:22 GMT+03:00 Gaurav Bajaj : > Great. Thanks for prompt reply. What is the way to indicate same via > configuration? > > For example, for Address it will be as per below, but not sure how to do > it for City. > >

Re: How to pass variable to the configuration file

Hi AG, That looks good. Now I can set my properties file ${MY_APP_HOME}/conf/apache-ignite.properties accordingly for the production cluster and failover cluser: * Production nodeIpAddresses=10.22.3.30,10.22.3.31,10.22.3.32,10.22.3.33 * Failover nodeIpAddresses=10.22.4.30,10.22.4.31,10.22.4.32,1

Hello! I have got a problem. I have 3 ignite (1.7 ver) nodes in the test cluster. On one of them placed ignite server with NodeFilter class that is locally available but I can’t deploy service “km.service” with provided NodeFilter into the cluster (when number of ignite service > 2) ClassNotF

Re: NullPointerException on ScanQuery

The difference is the first method returns all primary partitions for given node ID and topology version while the second returns all node IDs that own by given partition on given topology version. Did you executed query on stable topology? Is it reproducible problem? On Wed, Dec 7, 2016 at 12:06

Update a column of cache entities - Ignite 1.7

HI, is there any way to update a column value in ignite other than EntryProcessor ? IgniteCache#invokeAll(keys, EntryProcessor) need the keys in hand.

Yakov, We are configuring 47101 port for external address resolver. I provided code we use to configure ignite node in my original post. Essentially for one of the node it will be like this: (port 47101 is just one port we chose as it was one of unused port) Are you suggesting if we use address

Re: How can I call a Java Service from .NET

Pavel, Awesome, I didn’t know Service Grid is capable to work this way! You should have documented this feature earlier ;) However, this statement doesn’t look 100% true All nodes (Java-only and .NET) should have Java service classes deployed locally. See Ignite Java documentation: Service Grid

Re: peerClassLoading

Hi Alisher, A node filter must be added to the classpath of all the nodes regardless of the fact whether you’re going to deploy a service there or not. Please refer to this documentation section for more details https://apacheignite.readme.io/docs/service-grid#deployment-management

Re: Update a column of cache entities - Ignite 1.7

You can send IgniteCompute.affinityCall() to the primary node that holds the partition you are interested in. Inside the closure you can have iteration and invoke() calls that will be local to the primary copy. If you need to process the entire cache data set then send as many affinityCall's as you

Re: Not able to join cluster with Zookeeper based IP finder

I think it can work fine if along with incorrect addresses node also get correct (means address that is listened to by Ignite on some host) addresses on start. AddressResolver should be used if you want to build topology having different parts of it behind NAT, for example. If it is plain network,
