Ignite persistence to local disk vs to cassandra

I have a question: Does anyone have numbers which compare the speed of ignite when persistence is set to local file system as compared to when it is set to Cassandra? Tom This message may contain information that is confidential or privileged. If you are not the intended recipient, please

Re: Ignite running on JDK10? (Maybe Solved)

Added the exports to the SpringBoot plugin seem to work for me in addition to having them in my compiler and surefire plugins...it at least starts up Ignite and I see the Ignite banner. org.springframework.boot spring-boot-maven-plugin

I just want A module: node a1 a2 make cache cache_a be persistence and balance in A module only with persistence region p_region B module node b1,b2 with cache cache_b be non_persistence and distribute in B module.B will access cache_a and have same region p_region for persistence even cache_b

Re: Is Cache reads take long time with cache size increase?

Hello! The expectation is that increase should be logarithmic. In your case you should not expect 10 times increase, but 2-3x. However, if the operations take very short time their latency becomes irrelevant, you should really be looking at throughput. If for some requests latency starts to

Re: Ignite running on JDK10?

As a note, I downgraded all of the Docker containers to use JDK 9 (9.0.4) and I still get the same problem running the SpringBoot 2 application. Running in my IDE a test case works perfectly fine. *Caused by: java.lang.RuntimeException: jdk.internal.misc.JavaNioAccess class is unavailable.*

Re: Ignite.NET tasks cancellation

Hello! I try running this code, and I observe "System.Threading.Tasks.TaskCanceledException: A task was canceled." in Run() method. This is not quite what you are expecting, as you seem to expect jobs to be cancelled and not task, but from the code it's logical that it will happen. As for code

Re: Proper config for IGFS eviction

Ignite running on JDK10?

We are currently integrating Apache Ignite v2.6.0 into our platform. We upgraded to JDK9 just to make sure we were compliant and then upgraded to JDK10 try and preemptively catch anything planned for removal. I can run Ignite great in test cases but when I go to startup a SpringBoot 2

Re: Node with BaselineTopology cannot join mixed clusterrunningincompatibility mode

Hi, Arun When daemon node (visor) first time join the cluster it switch the cluster to compatibility mode. In this mode node containing baseline topology information will fail to join even if daemon node already leave the cluster. This issue was fixed by ticket [1] and will be available in Ignite

Is Cache reads take long time with cache size increase?

Hi, Wile working with Ignite we came across a situation where it is taking 10 time more time while reading records. Our initial cache size is 390,746 (count) Cache size increased to 7,297,301 (count) Now it is taking 10 times more time. Could you please suggest any performance tuning? Thanks

Re: Persistence with Spring Data

I think it should be possible. You can define Spring Data caches in configuration, and you can specify data region on per cache basis. You will have two data regions, persistent and non-persistent: https://apacheignite.readme.io/docs/memory-configuration#section-data-regions Regards, -- Ilya

Persistence with Spring Data

Hi all Is it possible to have persistence enable for just a single table when using Ignite through Spring Data rather than having it enabled for all the tables?

Re: SEVERE: Failed to resolve default logging config file: config/java.util.logging.properties

To avoid this error, you should place config/java.util.logging.properties in your IGNITE_HOME directory(it can be resolved in your jar directory, if it was not set before). At the same time, this excpetion: java.lang.ClassNotFoundException: org.apache.ignite.logger.java.JavaLoggerFileHandler

Re: apache ignite cassandra persistentStore for enum fields

Hello! I can see the following in code: fieldVal = NUMERIC_TYPES.contains(field.getDatabaseFieldType()) ? val.ordinal() : val.name(); As you can see here, if the column is numeric then ordinal is stored, otherwise it's name. Which is the one that you want. Just specify the appropriate

Re: apache ignite cassandra persistentStore for enum fields

Hi, I have the same issue with CacheJdbcPojoStore with writeBehind persistency in SQL DB. Is it only possible to store ENUMs as BLOBs or is there any other way to map them as strings, or anything else? I got the ENUMs both in the Key and Value fields. Regards Michal -- Sent from:

Re: Using more memory than is physically available

Hello! If you want to store more data on node than available Data Regions memory, your course of action should be Ignite Native Persistence. You can also use Expiry if the data is not crucial and you want to put limit on amount of data. Regards, -- Sent from:

Re: Ignite with POJO persistency in SQLServer

Thanks for this, this clarifies a lot. Could you only advise which data type should be used and how to map the field of type which is my class? Should I use BINARY or this cannot be handled at all? My intuition is that I should map the my.package.ListingCode to the java.sql.Types.JAVA_OBJECT.

Re: Using more memory than is physically available

I can afford to lose data. My ignite cache is embedded within an application running in open shift (docker containers) and has setClientMode(false). All data stored in docker containers is lost on pod restarts. Which would be preferable? Using ignite persistence or swap space? -- Sent from:
