Hi Ilya, at the time of running the experiments in the logs, there was no queries running in the background. Just 30 servers and no clients. What could have caused such high heap usage? -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/

Re: REST API requests hang with no response

Hi Ilya, I'm attaching the `jstack` dump to this message.  When I took the dump, there were ten requests that had been made to the Apache Ignite REST API using POST data of the form:     cmd=add&key=[key]&value=[value] ... where [key] and [value] were proper URI encoded data. Thanks in adva

Re: How to configure primary data in memory and backup data on disk?

You can not do this, Apache Ignite even can use the same memory page to store primary records and backup records, however, don't worry, Ignite will keep in memory the most recently used memory pages: https://cwiki.apache.org/confluence/display/IGNITE/Ignite+Durable+Memory+-+under+the+hood#IgniteDur

Getting error while extracting Date Fields from ignite cache using node express

Hi, We have an Oracle Table for which a corresponding cache/table is created in ignite and loaded using Cache JDBC POJO Store. On top of this cache a Rest API is built using node express. We are fetching the data from the cache using sql fields query and the programming language used is node js.

Re: tailing Ignite cache for events?

No, it's not possible to do in Visor. You can use a client node to start this Continuous Query. For this purpose you can also register listeners for events: https://apacheignite.readme.io/docs/events. It can be done for one of the Lifecycle events. Evgenii ср, 19 февр. 2020 г. в 17:40, Andrew Mun

Re: Offheap memory consumption + enabled persistence

>But I am still confused. Did I understood properly that each node should have enough memory to store full data set? No, it's not the case. It's just preallocating this memory with internal structures and shows it in the metrics. -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/

REST API requests hang with no response

Hi all, I'm seeing issues wherein the Apache Ignite REST API appears to accept requests, but doesn't ever reply.  This doesn't always happen; for example, if I make a request that I expect the API to reject, I get back a response: -- # curl -v -X GET 'http://127.0.0.1:8080/ignite' *

Re: Serialisation issue.

Hello! I, for one, do not recommend using new Collection() {{ }} in your configurations. It will create a non-static anonymous class, which may bind arbitrary amount of symbols from current lexical content, which will then need to be serialized to be sent to other nodes. Please use other ways
