Re: Determining BinaryObject field type

Dave, I suppose there isn't way to delete the schema. You could get the meta information about binary objects using Ignite#binary() method. For example ignite.binary().type("package.Employeee").fieldTypeName("name"). Thanks, Pavel 2018-03-24 1:10 GMT+03:00 Dave Harvey :

Re: JTA transactions in Iginte

Val, Thank you for the response. As per your suggestion I will first test it with write through approach before moving to JTA. About JTA, I still have some doubts about how to use it. As per the example given in this link https://apacheignite.readme.io/v2.4/docs/transactions (Integration With

Re: Any idea what this is ?

Hi! It behaves a bit different if I try to use BinaryConfiguration.SetClassNames, I added the following to the Ignite configuration, I hope that is the correct way to do it ? http://www.springframework.org/schema/beans;    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance;   

Re: Determining BinaryObject field type

I had stopped at BinaryObject, and didn't follow the indirection though type() to BinaryType. I think I assumed that this had only information at the higher level, and wouldn't drill down into the fields. This also answers a question about how to enumerate the fields. Thanks. -DH On Wed, Mar

Re: Ignite integration with Tableau

Hi Swetha, Would you please check if there is no network issue, dns name resolved correctly and 10800 port is not blocked by firewall? E.g. you can try to ping host and if it is ok then try connect to bkcttplna0***:10800 via telnet. On Wed, Mar 28, 2018 at 12:54 PM, Swetha

Re: Redis KEYS command?

Hi, As I understand, you need this command in SQL query, right? AFAIK, there is no plans to add Redis dialect support. If you need a way to achieve same results via SQL query (JDBC\ODBC for example), you can try to use custom SQL functions [1]. [1]

Re: Redis KEYS command?

Hi Jose, All availavle information about ingine/redis compatibility you can see here: https://apacheignite.readme.io/docs/redis If you are going tobe informed about the last information about future integrations then you can read articleы from еру official site:

Baseline Topology and Node Failure

The introduction in 2.4 of Baselines seems quite helpful. If a node restarts, it will avoid excessive rebalancing. What is unclear from the documentation is what happens in the case where a node fails, and doesn't come back. I'm assuming that in fact nothing happens, except that the backups

Running heavy queries on Ignite cluster on backing store directly without impacting the cluster

Hi I am using ignite 2.3 with native persistence layer as backing store We do have close to half to 1 billion records in each of the tables. There are some adhoc requirements to query the tables with diffrent where conditions, columns which we use in where clause may not have indexes, which may

Re: Getting "BinaryObjectException: Failed to deserialize object" while trying to execute the application using multi node

Michael, There is no much detail to add. Although it's technically possible to serialize lambdas and anonymous classes, it's usually not recommended, as they can reference some objects from outside. If these objects are not serializable (or not intended to be serialized), you're likely to get

Upgrade from 2.1.0 to 2.4.0 resulting in error within transaction block

Code works in Ignite 2.1.0. Upgrading to 2.4.0 produces the stack trace below. The delete statement that is causing the error is: SqlFieldsQuery sqlQuery = new SqlFieldsQuery("delete from EngineFragment where " + criteria()); fragmentCache.query(sqlQuery.setArgs(criteria.getArgs())); The code

Re: JTA transactions in Iginte

Prasad, 1. JTA is an abstraction that is not related to Ignite, so exact details would depend on how your application is organized. But basically you need to do the following: - Acquire the transaction manager (from a container, from Spring app context or whatever you use for management of such

Re: Determining BinaryObject field type

Dave, There is one way to delete meta data. You could find typeId using ignite.binary().type("package.Employeee").typeId() and remove .bin files in all *binary_meta* subfolders. ​
