![]() Easily specify environment specific profiles with different property values, i.e.maven-resources-plugin, maven-dependency-plugin & maven-jar-plugin.We already shared on Crunchify some time back. Lots of available and widely used Maven Plugins for number of different usecases.jar files will be downloaded at user side from central location. No more complicated build.xml file for your Java Production Project.Everybody gets the same dependencies, hence – no more compilation or other error. This will solve an issue with dependencies. All the members in team uses the same and only one pom.xml version. Maven project contains only one pom.xml file.Why Maven? What are the advantages using Maven with Java / Dynamic Web Project? I don’t see any other combination which best works. BEST_EFFORT (default) Spline will try to initialize itself, but if fails it switches to DISABLED mode allowing the Spark application to proceed normally without Lineage tracking.Maven and Java is a best combination you could get for your production project in present time.wrong configuration, no db connection etc) the Spark application aborts with an error. REQUIRED If Spline fails to initialize itself (e.g.DISABLED Lineage tracking is completely disabled and Spline is unhooked from Spark.Spline combine these properties from several sources: You also need to set some configuration properties. Data lineage of the job will be captured and stored in the // configured database for further visualization by Spline Web UI Properties then run some Dataset computations as usual. enable data lineage tracking with Spline import za.co._ sparkSession. ![]() Make sure you have JDK 8, Maven and NodeJS installed. Note: Skip this section unless you want to hack with Spline za.co.absa.spline:spark-agent-bundle-2.4:0.4.2 (For Spark 2.4)Īlternatively, build Spline from the source code.There are two ways how to do it: Download prebuild Spline artifacts from the Maven repo To get started, you need to get a minimal set of Spline’s moving parts -Ī server, an admin tool and a client Web UI to see the captured lineage. Our focus is not only business-oriented we also see Spline as a development tool that should be able to help developers with the performance optimization of their Spark jobs. Identification of performance bottlenecks Moreover, it would be beneficial for them to have up-to-date documentation where they can refresh their knowledge of a project. Regulatory requirement for SA banks (BCBS 239)īy 2020, all South African banks will have to be able to prove how numbers are calculated in their reports to the regulatory authority.īusiness analysts should get a chance to verify whether Spark jobs were written according to the rules they provided. Our main focus is to solve the following particular problems: Spark jobs shouldn’t be treated only as magic black boxes people should be able to understand what happens with their data. Spline aims to fill a big gap within the Apache Hadoop ecosystem. Spline is aimed to be used with Spark 2.3+ but also provides limited support for Spark 2.2. Check the examples to get a better idea how to use Spline. Web UI application that visualizes the stored data lineages.Rest Gateway, that receive the lineage data from agent and stores it in the database.Spark Agent that sits on drivers, capturing the data lineage from Spark jobs being executed by analyzing the execution plans. ![]() ![]() The project consists of three main parts: Please use a recent Spline version.ĭata Lineage Tracking And Visualization Solution This Spline version has reached the End-Of-Life and is not maintained anymore.
