Re: Apache Ignite is how to ensure the data's consistency between multiple server?

2016-03-01 Thread Christos Erotocritou
If you use full sync mode for backups, then the client node will wait for write or commit to complete on all participating remote nodes (primary and backup). This is the most restrictive configuration but will guarantee data consistency. In addition if you use transactions for any grid

Re: Distributed Closures VS Executor Service

Hi Kyriako, - If I want to pass data to callables, for example Lists of objects, small to -medium size (collections from 2000 to 6000 objects maximum, with average object size some ~200KBs) what is the best way to do this: to pass them as argument in callables or put them in the distributed cache

Non-collocated distributed SQL Joins across caches over separate cluster groups

2017-04-05 Thread Christos Erotocritou
Igniters, Is it correct to assume the following: We have an Ignite cluster comprised of 2 cluster groups A & B that have different caches deployed. We use an Ignite client to obtain API access to the whole cluster and execute a join query that joins data across the 2 caches My understanding

Re: Distributed Closures VS Executor Service

Hi Kyriako, Agree with Nikolai on both points. Regarding point number 2, you want to use affinity data / data colocation and data / compute colocation. You basically need to ensure that when you are inserting data into the cache you use the same affinity for all entries that need to be

Re: Computation best practices

2017-11-13 Thread Christos Erotocritou
Hi Luqman, Is there a specific reason why you want to keep the data nodes separate from the compute nodes? As you say this beats the point of collocation. You should use the data nodes for compute and ensure you have a way to monitor and kill spurious tasks that may be executed on the grid.

Hi Rajesh, Ignite is a distributed system, testing with one node is really not the way. You need to consider having multiple nodes and portion and collocate your data before. Thanks, C > On 5 Feb 2018, at 16:36, Rajesh Kishore wrote: > > Hi, > > We are in the
