ETL in minutes > Extract from the sources that run your business. Data is extracted from online transaction processing (OLTP) databases, today more commonly known just as 'transactional databases', and other data sources. OLTP applications have high throughput, with large numbers of read and write...

It’s tempting to think a creating a Data warehouse is simply extracting data from multiple sources and loading into database of a Data warehouse. This is far from the truth and requires a complex ETL process. The ETL process requires active inputs from various stakeholders including developers,...
Data integration, data blending, and data joining all start at the same step: combining multiple sources of data. These techniques differ in the level of standardization in definitions and nomenclature and where in the process transformations occur. When deciding which method to use, ask questions ...
Data integration pipelines concentrate on merging data from multiple sources into a single unified view. These pipelines often involve extract, transform, and load (ETL) processes that clean, enrich, or otherwise modify raw data before storing it in a centralized repository like a data warehouse or...
It is an open-source ETL tool. It provides a drag-and-drop interface. We can deploy it easily in the cloud environment. It has more than 900 built-in components to connect different data sources. It has an online user community to provide technical support to users. ...
Collection Data Sources: Flink提供了一些Java集合支持的特殊数据源来使得测试更加容易,程序测试成功后,将source和sink替换成真正source和sink即可。 final StreamExecutionEnvironment env = StreamExecutionEnvironment.createLocalEnvironment(); env.fromElements(1, 2, 3, 4, 5); ...

Fast, efficient data flow engine—The data flow engine extracts data from one or more data sources, performs any necessary transformations on the extracted data, and then delivers that data to one or more destinations. To maximize efficiency, the data flow engine takes advantage of in-memory pro...
In the second part of this post, we walk through a basic example using data sources stored in different formats in Amazon S3. Using a SQL syntax language, we fuse and aggregate the different datasets, and finally load that data into DynamoDB as a full ETL process. ...
