            How do I use a Transaction in a Reactive Flow in Spring Integration?
            Asked 2021-Jun-15 at 18:32

            I am querying a database for an item using R2DBC and Spring Integration. I want to extend the transaction boundary a bit to include a handler - if the handler fails I want to roll back the database operation. But I'm having difficulty even establishing transactionality explicitly in my integration flow. The flow is defined as

            Well, it's indeed not possible that declarative way since we don't have hook for injecting to the reactive type in the middle on that level.

            join unordered pairs of connected edges using numpy only
            Asked 2021-Jun-15 at 08:27

            I have a concave hull (not convex) that I have the points for eg: A,B,C,D,E. I've gotten the pairs of points that make up the outer edges. [A,B],[A,E],[C,D],[B,C],[E,D]. (This is a very simplified version)

            I want to get the connected points in order (CW or CCW doesn't matter) so I can use them as a contour.

            But the pairs are not ordered, you can see A goes to B, then A goes to E, etc. The only solution I had was searching for each point and its next pair sequentially in a loop

            Is there a way to solve this using numpy only in a vectorized manner so that its fast for a large array of edges? I know shapely exists but I have trouble installing it and I'd prefer no external dependancies

            Does the number of kafka partitions increase the speed of Spark writing to kafka?
            Asked 2021-Jun-14 at 14:31

            When reading, Spark have a mapping 1:1 to kafka partitions, so, with more partitions we can leverage more parellelism to our job.

            But does it apply when Spark is writing in kafka ? Writing the same dataset in one topic with 4 partitions is more fast than writing in a topic with 1 partition ?

            ...

            ANSWER

            Answered 2021-Jun-14 at 14:31

            Yes.

            If your topic has 1 partition means it is in one broker. So, If you increase producer rate for the topic, then that broker becomes busy. But if you have multiple partitions, your Kafka cluster shared those partitions into different brokers and those production rate shared within multiple brokers. So, Writing the same dataset in one topic with 4 partitions is more fast than writing in a topic with 1 partition.

            This not only production rate. In Kafka brokers, There is multiple processes like compactions, compressions, segmentations etc... So with number of messages, that work load becomes high. But with multiple partitions in multiple brokers, it will be distributed.

            However, you don’t necessarily want to use more partitions than needed because increasing partition count simultaneously increases the number of open server files and leads to increased replication latency.

            from kafka documentation

            Distribution The partitions of the log are distributed over the servers in the Kafka cluster with each server handling data and requests for a share of the partitions. Each partition is replicated across a configurable number of servers for fault tolerance. Each partition has one server which acts as the "leader" and zero or more servers which act as "followers". The leader handles all read and write requests for the partition while the followers passively replicate the leader. If the leader fails, one of the followers will automatically become the new leader. Each server acts as a leader for some of its partitions and a follower for others so load is well balanced within the cluster.

            The problem is you are passing respons.body["data"]["data"] to your Datum.fromJson() constructor but there is no such key in the json. on the other hand you are passing response.body["data"] to Car.fromJson() constructor which is a list of data that does not have "status" key in it.

            How to convert STIX objects to Pydantic models?
            Asked 2021-Jun-11 at 08:46

            I'm using FastAPI and I need to represent different STIX 2 objects (from MITRE ATT&CK) with a corresponding/equivalent Pydantic model in order to return them as a response JSON.

            ANSWER

            Answered 2021-Jun-11 at 08:46

            A possible and promising approach is to generate the Pydantic model starting from the corresponding JSON Schema of the STIX object.

            Luckily enough the JSON schemas for all the STIX 2 objects have been defined by the OASIS Open organization on the GitHub repository CTI-STIX2-JSON-Schemas.

            In particular, the JSON Schema for the Attack-Pattern is available here.

            For a specific solution to your immediate problem, you need to modify the condition in selected= to include the case that you want, something like || (item === 'Pool' && location.pathname === '/') or similar. You may have to fiddle with it.

            As a broader answer, consider using react-router's built-in NavLink component. They already have an isActive prop specifically for dealing with complex cases like this. No sense reinventing the wheel.

            Query on usage of on-premises data gateway for connecting Azure Analysis Services
            Asked 2021-Jun-07 at 14:35

            I have an application hosted in Azure infrastructure IaaS model. In this case, database: SQL Server 2017 is managed using Azure VM. For enhanced security isolation , the entire setup including the database server is leveraging VNets. Now we are planning to leverage Azure Analysis Services: PaaS offering to host the data models in the Azure environment and allow the client apps: Excel to connect it to create reports and perform ad-hoc data analysis on the data.

            Since in this case both the data source and the Azure Analysis service are hosted in Azure environment, do we still need to use On-premises Data Gateway to connect the Tabular Models hosted in Azure Analysis Services with the data sources hosted in Azure VM through On-premises Data Gateway

            Answer - Azure Analysis Services is unable to join a VNET. The best solution here is to install and configure an On-premises Data Gateway on the VNET, and then configure your Analysis Services servers with the AlwaysUseGateway server property.
