New blog post on Apache Ignite in AWS

Hello community, Recently I published a new blog post on getting started with Apache Ignite in AWS [1]. I tried to make my example as simple as possible while keeping it usable. Let me know if this post is useful for you. I plan to write several follow-up posts about AWS-specific things but

I totally agree with you, that model saving is missed element in this framework. In this release I've experimented with binary format and with a commonly used format PMML (in scikit-learn and in Spark 1.0) https://en.wikipedia.org/wiki/Predictive_Model_Markup_Language This is a link to the

Re: Add user attributes to thin clients

I've looked through the PR more closely, trying to understand the use case, and there are some Java-specific things going on (left a comment). Please keep in mind that we have thin clients in Python, Node.js, C++, C#. The protocol must be language-agnostic. If we add some features there, let's

Re: Add user attributes to thin clients

The approach with UserAttributes map looks dirty to me and raises questions: - Why is UserAttributes property related to authentication? - UserAttributes name implies that users can put there anything they want, but what for? What are those additional use cases? I think we should focus on a

Re: Add user attributes to thin clients

I think we should add this. It will provide an extra level of security. This approach is used in many products, for example in AWS (MFA). [1] [1] https://docs.aws.amazon.com/general/latest/gr/aws-sec-cred-types.html#multi-factor-authentication ср, 22 янв. 2020 г. в 18:13, Andrey Kuznetsov : > >

Hi, Pavel! Sometimes single authentication factor is not enough. Attributes proposed allow to add extra factors flexibly. ср, 22 янв. 2020 г., 17:39 Pavel Tupitsyn : > Token can be sent instead of a password (like git works with GitHub > tokens). > > For now I don't see a reason to include

Re: Apache Ignite 2.8 RELEASE [Time, Scope, Manager]

Good idea about pre-release build of ignite-2.8 branch. However, I would not name it `rc`, since it is not really a release candidate. Make it `pre0` or something like that. For Ignite.NET I've uploaded pre-release NuGet packages built from current ignite-2.8 branch:

Re: Add user attributes to thin clients

Token can be sent instead of a password (like git works with GitHub tokens). For now I don't see a reason to include attributes into the handshake message. On Wed, Jan 22, 2020 at 5:32 PM Ilya Kasnacheev wrote: > Hello! > > One does not send security certificate as attribute. The only way to

Re: Add user attributes to thin clients

Hello! One does not send security certificate as attribute. The only way to obtain peer security certificate is to ask SSL engine to provide it. Nevertheless, I can see how it can be useful with e.g. Kerberos, which is token-based IIRC. Regards, -- Ilya Kasnacheev ср, 22 янв. 2020 г. в

Re: Add user attributes to thin clients

This map is something like user object from `SecurityCredentials`. Sometimes login and password are not enough for security checks. For example, we can send security certificate and validate it inside authenticator. ср, 22 янв. 2020 г., 17:16 Igor Sapego : > Hi Dmitrii, > > Can you please

Add user attributes to thin clients

Hello, Igniters! I want to add the possibility of sending user defined attributes from thin clients. And check them inside custom authenticator during handshake [1]. There is an issue in hardcoded binary writer for JDBC and `IgniteClient`. This writer searches for a classes in the JDK and
