Sampling a large dataset flowing through this plugin to pull random records. Supports two types of sampling i.e, Systematic Sampling and Reservoir Sampling.
CDAP version 3.5.x or higher.
You get started with Sampling plugin by building directly from the latest source code::
git clone https://github.com/hydrator/sampling-aggregator.git cd sampling-aggregator mvn clean package
After the build completes, you will have a JAR for each plugin under each
<plugin-name>/target/ directory.
You can deploy a plugin using the CDAP CLI::
load artifact <target/plugin-jar> config-file <resources/plugin-config>
load artifact target/sampling-aggregator-plugin-.jar
config-file target/sampling-aggregator-plugin-.json
You can build without running tests: mvn clean install -DskipTests
- UI doesn't support schema's with hyphens (-), so the plugin currently transforms all the schemas with - into underscores (_). This change will be reverted after this is fixed: https://issues.cask.co/browse/HYDRATOR-1125
