Re: Logging documentation

Great! I think the next task should be to explain expiration vs eviction. I am seeing too many questions on it as well. At this point, I am also confused about how it really works. D. On Fri, Sep 8, 2017 at 10:18 AM, Denis Magda wrote: > Unbelievable! So many years went by

Re: What's the current behaviour when we use the eviction filter + expiry plicy?

Hi Aaron, I don't see anything similar for expiration like for eviction. I think the easiest solution is to put that data to another cache with no expiration policy. Thanks, Mikhail. -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/

Re: Design question on the Ignite Web Session Clustering.

Hi, I answered in SO, I copy it here: """ if you have a local cache for sessions and sticky sessions why do you need to use ignite at all? However, It's better to go with ignite, your app will have HA, if some node is failed, the whole app still will work fine. I agree you should split app

Re: Cache Size Monitor -- without making a remote call??

Chris, I feel maybe there is a misunderstanding of how partitions assignment works in Ignite. In brief, Ignite has public AffinityFunction interface, which is responsible for assigning

Re: Cache Size Monitor -- without making a remote call??

Chris, Do you need other metrics besides the cache size? If not, then your code above could be replaced with one line: return ignite.cache(cacheName).localSize(CachePeekMode.PRIMARY); -- Best regards, Alexey

Re: Message Queue Size

Hi Rishi, Yes, but you need set heap size at least 512M and proper off-heap size [1]. But you won't be able to store large amount of data, you will need to enable persistence, it will allow to extend available memory with dis k[2]. [1]

Re: Cache Size Monitor -- without making a remote call??

Thank you very much for responding. Yes, I am concerned whenever a call must be made to remote machines, particularly when used by my monitoring framework -- because without that data I am relatively blind. And that call (for all metrics) must be very fast and not affect performance. Yesterday,

Hi Michal, I've looked at code and your points look reasonable. In now moment, how you correct noted, you can decrease size of the buffer via IGNITE_CONTINUOUS_QUERY_SERVER_BUFFER_SIZE property to 50 or 100. On Tue, Sep 5, 2017 at 9:14 PM, mcherkasov wrote: > Hi

ignite.destroyCache() method hangs the cluster

Hi, We have a test machine which has 8 cores with 32Gb ram. We are using ignite 1.8.3. On ignite there is only one cache which has 10M records (db size 7Gb~ ignite cache size 14Gb~) We reload this cache with a cron scheduler.(Every night) For example: cacheName: products (alias) realCacheName:

Re: Why is PageSize limited to just 16kB?

Hi John, Quite long page will require Ignite to use much time during loading page from disk or write it back during checkpointing. Ignite is able to change field value pointwise within page in case of update. In that case and if too long page is selected, one field update, for example 1 byte

Re: Cache Size Monitor -- without making a remote call??

Hi Chris, As I understand your concern is "Many times I have seen this particular call take quite a while to return". Are you concerned with asynchronous nature of IgniteCache#size() or you think the existing implementation is too slow and your own implementation would be faster? If this is the
