EXPRESSION LANGUAGE
The Data Pipeline Expression Language (DPEL) is similar to that found in the Java language. It contains a few additions that make it easier to read for developers and non-developers alike. The DPEL engine is used by several endpoints to parse and evaluate expressions at runtime. This allows expressions to be treated as configurationinstead of

XML Examples. DATAPIPELINE FOUNDATIONS DataPipeline Foundations is an add-on library to the core DataPipeline engine. It provides a set of high-level components that are needed in many data processing and decisioning applications. The components in DataPipeline Foundations can be used on their own or integrated into your existing DataPipeline jobs.DATA MAPPING
Data mapping is a quick way to transform data from source to target using expressions and functions. It's a high-level tool that can fulfill most mapping needs without relying on the lower level readers and writers in DataPipeline core. The online data mapping demo tool uses this feature behind the scenes. WHAT IS DATA PIPELINE Overview. Data Pipeline is an embedded data processing engine for the Java Virtual Machine (JVM). The engine runs inside your applications, APIs, and jobs to filter, transform, and migrate data on-the-fly. Data Pipeline speeds up your development by providing an easy to use framework for working with batch and streaming data inside your apps. DATA PIPELINE JAVADOC Packages; Package Description; com.northconcepts.datapipeline.avro: com.northconcepts.datapipeline.buffer: com.northconcepts.datapipeline.core: com.northconcepts HOW TO SPEED UP JDBC INSERTS? 3. Use Batch Inserts. Prepared statements are your friend when using JDBC, but batch statements are going to be your BFF when doing inserts and updates. We have a demo in Data Pipeline that loads some hospital data into a MySQL database. Using batch statements of 100 records, insert time dropped from 3.5 minutes to under 1 second.CONVERT JSON TO CSV
import com.northconcepts.datapipeline.json.JsonReader; public class ConvertJsonToCsv {. /* Consumes the following JSON (line breaks added for clarity). Yes, it starts with a new line an two slashes. // [. HOW TO QUERY JAVA OBJECTS WITH XPATH The addField method takes the name of the new, target field and an XPath 1.0 location path to identify each field of the record.. The addRecordBreak method takes another XPath 1.0 location path to identify each record’s boundary. The reader returns a new record whenever this pattern is matched. The returned record contains all fields (from addField matches) that have been captured up to that WRITE A CSV FILE TO FIXED WIDTH Write a CSV File to Fixed Width example.

Code your extract, transform, load pipelines using a high performance language that fits your team's skills, has a mature toolset, and is easy to understand and maintain. EMBEDDED OR STANDALONE Integrate pipelines into your web, mobile, desktop, and batch applications or run them as separate, standalone jobs. RUN PIPELINES LOCALLY Develop and test pipelines locally on your desktop using your existing development and debugging tools. SCRIPT TRANSFORMATIONS When you need to move quickly, skip the compile step and script transformations in JavaScript, Groovy, and other languages that run on the Java Virtual Machine.MANAGE CHANGE
Track changes in Git or other source control systems, code review ETL logic with your team, and plug pipeline development into your CI/CDprocess.
STREAM REAL-TIME OR BATCH Set your pipelines to run on a schedule, when data is available, when an event or manual trigger occurs, or you can run them continuously to gain insight in real-time.CUSTOMIZE
Enhance the engine to fit your unique needs. Plug in your own logic or modify existing behavior to your specific requirements. GET MEANINGFUL ERRORS When exceptions occur, get the exact line of code, the data that was being processed, and a readable description of all the transformationsin the pipeline.
PROCESS IN-MEMORY
Processing data one piece at a time as it moves through the pipeline can be more than 100x faster than first storing it to disk to query orprocess later.
