Re: Usage of DataStreamer for bulk loading

Hi Naveen, FYI there an issue in JIRA: IGNITE-6917 SQL: implement COPY command for efficient data loading https://issues.apache.org/jira/browse/IGNITE-6917 And it is already merged to master and will be a part of ignite 2.5. -- Alexey Kuznetsov

RE: Does Merge statement (DML) work with JDBC client driver

Naveen, Ignite provides out of the box implementation for RDBMS. The easiest way to integration would be to use Web Console to generate all required POJO classes and configurations: https://apacheignite-tools.readme.io/docs/automatic-rdbms-integration -Val -- Sent from: http://apache-ignite-us

Re: Usage of DataStreamer for bulk loading

Hi Naveen, I had similar situation. Two things you can do : 1. Decouple file reading from cache streaming, so that both can be handled in separate threads asynchronously. 2. Once you have data from csv in collection, use use parallelStreams to add data in streamer with multiple threads. Thanks,

Re: Correct build process for Ignite

I suspect this happens because you have a repository mirror defined in your .m2/settings.xml that matches all repos. For example: my-mirror my-repo http://acme.com/my-repo * From: vkulichenko Sent: Thursday, March 8, 2018

Re: eviction performance

Hi Stanislav, Thanks for info and the note on the terminology. So in my setup im partitioning by chunks of time. If I turn eagerttl to false how would the cleanup look? Would I periodically scan the partitions that i want to be expired? Are there any best practices to that end? Additionally ar

RE: Does Merge statement (DML) work with JDBC client driver

Hi Stan I do not want to Oracle with native persistence, I only wanted to use Oracle persistent layer. Are you sure, we need to implement cacheStore for each table we have in the cluster ? If that is the case, we need to have separate code base for Oracle as persistence layer and another versio

RE: How to configure a cluster as a persistent, replicated SQLdatabase

Hi Naveen, Please refer to this page https://apacheignite.readme.io/docs/3rd-party-store. In short, you need to implement a CacheStore or use one of the standard implementations (CacheJdbcBlobStore, CacheJdbcPojoStore) and add it to your cache configuration. Also, you can set DataRegionConfigurat

Re: How to configure a cluster as a persistent, replicated SQL database

Hi Jose I was asking how can I configure Oracle DB as persistent layer. At the moment I am using the Ignite native persistence as persistent layer, but I would like to use Oracle DB as persistent layer. How can I do this, what changes I should do to the config file. My config file looks like this

Re: Usage of DataStreamer for bulk loading

Hi DH I am not using any custom streamReciever, my requirement is very simple. Have huge data in CSV, reading line by line and parsing the line and populating the POJO and using the DataStreamer to load data into cache. while (sc.hasNextLine()) { ct++;

Ignite reads are slower with getAll

Hi guys - I have a ignite cluster with persistence enabled that has 200 million events in it. Right now read throughput is around 3000 events per second. I have increased the IOPS to 1 and even then I have the same performance. Am I doing something really wrong or this is how it perform with la

RE: Data Recovery after cluster restart

Hi Naveen, The native persistence doesn’t require you to reload data to memory, the tables should be available after the activation. How do you start the nodes? Do you use ignite.sh/ignite.bat? Have you downloaded Ignite as .zip archive or via Maven? It’s possible that your persistence files are

RE: eviction performance

Hi, A terminology nitpicking: it seems that you’re talking about expiry; eviction is a similar mechanism but is based on the data size, not time. Have you tried setting CacheConfiguration.eagerTtl = false (https://apacheignite.readme.io/v2.3/docs/expiry-policies#section-eager-ttl)? With that se
