Beam Summit 2023 | Parallelizing Skewed Hbase Regions using Splittable Dofn - Prathap Reddy
Channel: Apache Beam
Date: 2023-08-01

During HBase to Cloud BigTable Migrations, HBase snapshots will be imported to Cloud Bigtable. Each Snapshot contains several HBase regions and certain HBase regions can be quite large due to skewed data. 
 
In this presentation along with code snippets and benchmark test results, we showcase how to parallelize a skewed HBase Regions using Splittable DoFn and reduce pipeline runtime.
