The document discusses implementing an event-driven architecture using events instead of synchronous APIs. It explains that events decouple services by allowing them to communicate asynchronously through a centralized event routing system. This loose coupling makes services more independent and resilient, as failures in downstream services do not block upstream ones. It also improves scalability a
Near Real-time Processing Over Hadoop and HBase
From MapReduce to realtime This post covers much of the Near-Realtime Processing Over HBase talk I’m giving at ApacheCon NA 2013 in blog form. It also draws from the Hadoop, HBase, and Healthcare talk from StrataConf/Hadoop World 2012. The first significant use of Hadoop at Cerner came in building search indexes for patient charts. While creation of simple search indexes is almost commoditized, we

Riding the wave of the generative AI revolution, third party large language model (LLM) services like ChatGPT and Bard have swiftly emerged as the talk of the town, converting AI skeptics to evangelists and transforming the way we interact with technology. For proof of this megatrend look no further than the instant success of ChatGPT, […] Read blog post

Apache HBase + Apache Hadoop + Xceivers - Cloudera Blog
Introduction Some of the configuration properties found in Apache Hadoop have a direct effect on clients, such as Apache HBase. One of those properties is called “dfs.datanode.max.xcievers”, and belongs to the HDFS subproject. It defines the number of server side threads and – to some extent – sockets used for data connections. Setting this number too low can cause problems as you grow or increase
Springframework.org
Spring Data’s mission is to provide a familiar and consistent, Spring-based programming model for data access while still retaining the special traits of the underlying data store. It makes it easy to use data access technologies, relational and non-relational databases, map-reduce frameworks, and cloud-based data services. This is an umbrella project which contains many subprojects that are speci
Hadoop/HBaseのNodeのdecommission
H系のOSSは何年か触っているのですが、良く考えてみるとNodeの縮退を行ったことがありませんでした・・・ ※数十台程度の小規模な環境でしか運用したことが無いことと、故障もRAIDのHDD程度でマシンの大掛かりな故障という事象も無かったので ということで、縮退を行いました。...

So we will write a map reduce program. Similar to the popular example word-count - couple of differences. Our Input-Source is a Hbase table. Also output is sent to an Hbase table. First, code access & Hbase setup The code is in GIT repository at GitHub : http://github.com/sujee/hbase-mapreduce You can get it by git clone git://github.com/sujee/hbase-mapreduce.git This is an Eclipse project.

Enterprises see embracing AI as a strategic imperative that will enable them to stay relevant in increasingly competitive markets. However, it remains difficult to quickly build these capabilities given the challenges with finding readily available talent and resources to get started rapidly on the AI journey. Cloudera recently signed a strategic collaboration agreement with Amazon […] Read blog p
