Learn about the design decisions behind HBase’s new support for MOBs.
Apache HBase is a distributed, scalable, performant, consistent key value database that can store a variety of binary data types. It excels at storing many relatively small values (<10K), and providing low-latency reads and writes.
However, there is a growing demand for storing documents, images, and other moderate objects (MOBs) in HBase while maintaining low latency for reads and writes.
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,
The following post about the new request throttling feature in HBase 1.1 (now shipping in CDH 5.4) originally published in the ASF blog. We re-publish it here for your convenience.
Running multiple workloads on HBase has always been challenging, especially when trying to execute real-time workloads while concurrently running analytical jobs. One possible way to address this issue is to throttle analytical MR jobs so that real-time workloads are less affected.
The following post, from Cloudera intern Jonathan Lawlor, originally appeared in the Apache Software Foundation’s blog.
Over the past few months there have a been a variety of nice changes made to scanners in Apache HBase. This post focuses on two such changes, namely RPC chunking (HBASE-11544) and scanner heartbeat messages (HBASE-13090). Both of these changes address long standing issues in the client-server scan protocol.
We are happy to announce the inclusion of Apache Phoenix in Cloudera Labs.
[Update: A new package for Apache Phoenix 4.5.2 on CDH 5.4.x was released on Nov. 19, 2015.]
Apache Phoenix is an efficient SQL skin for Apache HBase that has created a lot of buzz. Many companies are successfully using this technology, including Salesforce.com, where Phoenix first started.
