Re: Reduce Movement of data in cluster while data loading in PARTITIONED cache

One thing described here https://apacheignite.readme.io/docs/data-loading is 'Partition-aware data loading', which basically implies implementation of some kind of 'data partitioning' in your database so that each node only pulls a portion of data. Hope that helps. -- View this message in

Reduce Movement of data in cluster while data loading in PARTITIONED cache

Hi, Is there any way we can reduce movement of data across nodes in cluster while data loading, so that we can speed up data loading process? By observation I am getting better data loading rates in cache LOCAL mode as there is no movement of data across ignite instances. Can we do some

Re: NOT IN in ignite

Thanks Andrey. Ideally Affinity must be used to find the node of an entry and for joins to reduce the data transfer between nodes. With the current implementation, group by queries of a cache (with no joins) on non affinity key will not work :( . Cout queries are also behaving in the same way.

Re: NOT IN in ignite

Hi Anil, Query 1 results looks ok. You got different results as affinity key is equipmentId, but not serialnumber. Query 2 has aggregates in subquery that is not supported yet [1]. [1] https://issues.apache.org/jira/browse/IGNITE-3860. On Sat, Feb 11, 2017 at 7:18 PM, Anil

Re: NOT IN in ignite

Hi team, i fee this is a bug. i have loaded cache with affinity key and group by queries on non affinity key returning results per node with both collocate = true/false. i have any created INSTALL_BASE cache with key as AffinityKey and value is InstallBase pojo. and affinity key is equipmentId

Distributed job scheduling

Hi, Right now Ignite has only "scheduleLocal" functionality. However, it's not very fault tolerant. What is the best way to schedule regular a job on a cluster in future on *any* node with execution guarantees? Thanks, Sergei

Re: Apache Ignite's full config file...

Hi Abdul, If you mean Java IgniteConfiguration then it can be configured as a regular Spring bean, so there is no such thing as a complete Spring xml config. Still, you could refer to the official documentation and take a look at examples provided with sources for additional information. Kind
