Re: Reassign partitions

Hi, I don't understand. In your example part.2 was moved from Node1 to Node3. So all the entries will be moved to Node3 and the local store will be update as well. What is lost? -Val -- View this message in context: http://apache-ignite-users.70518.x6.nabble.com/Reassign-partitions-tp7461p762

Re: "OFFHEAP_VALUES" MODE (VISOR CONSOLE)

Hi, This is correct behavior. In OFFHEAP_VALUES mode, entries are actually stored on-heap, but in instead of values they have a pointers to off-heap memory. -Val -- View this message in context: http://apache-ignite-users.70518.x6.nabble.com/OFFHEAP-VALUES-MODE-VISOR-CONSOLE-tp7601p7618.html

Re: understanding Locks usage

Sam, Data access semantics are provided by transactions. You have different concurrency mode and isolation level to control it. There is no much sense to use lock for this. Answering other questions: 1. You have tryLock method timeout. Once again, Ignite lock provides everything that is available

Re: Overall desgn question

With replicated cache you don't need to collocate. You can try both approaches - a single cache for documents that have nested collection of pages, or two separate caches for documents and pages. -Val -- View this message in context: http://apache-ignite-users.70518.x6.nabble.com/Overall-desgn

Re: understanding Locks usage

Sam, as workaround you can use IgniteQueue in order to implement distributed exclusive lock. You can find example of such solution in vertx-ignite project. See IgniteClusterManager class [1], getLockWithTimeout() method and LockImpl class. [1] https://github.com/vert-x3/vertx-ignite/blob/master/s

Re: CacheJdbcPojoStore with MariaDB

Hi, @seyeony! In general Ignite need some heap for temp objects when loading entries to cache. I would recommend to use such very raw approximation: 200 bytes for entry, so max_heap = 200 * max_entries_numbers + 512MB (for Ignite system needs). But to have a clear answer - take a heap dump and fi

How to optimize Ignite when running on a virtual machine

Hi all, I have read the article about jvm and system tuning (https://apacheignite.readme.io/docs/jvm-and-system-tuning#section-detailed-garbage-collection-stats). I found it mainly focus on physical machines. But I use virtual machines. Is there any optimization for the virtual machine?

Re: CacheJdbcPojoStore with MariaDB

Hi Alexey, I gave more heap and I was able to load the whole dataset in cache. I have another questions. Eventhough I used OFFHEAP_TIERED in the configuration, why do I need more heap? Should I find the right heap size by trial and error or is there any calculation method? Should I give same heap
