How-to: Scan Salted Apache HBase Tables with Region-Specific Key Ranges in MapReduce

Categories: Guest HBase How-to

Thanks to Pengyu Wang, software developer at FINRA, for permission to republish this post.

Salted Apache HBase tables with pre-split is a proven effective HBase solution to provide uniform workload distribution across RegionServers and prevent hot spots during bulk writes. In this design, a row key is made with a logical key plus salt at the beginning. One way of generating salt is by calculating n (number of regions) modulo on the hash code of the logical row key (date,

Architectural Patterns for Near Real-Time Data Processing with Apache Hadoop

Categories: Data Ingestion Flume Hadoop HBase Kafka Spark

Evaluating which streaming architectural pattern is the best match to your use case is a precondition for a successful production deployment.

The Apache Hadoop ecosystem has become a preferred platform for enterprises seeking to process and understand large-scale data in real time. Technologies like Apache Kafka, Apache Flume, Apache Spark, Apache Storm, and Apache Samza are increasingly pushing the envelope on what is possible. It is often tempting to bucket large-scale streaming use cases together but in reality they tend to break down into a few different architectural patterns,
