Reverse Engineer MapR-DB with ODI

This is going to be a short write-up, a bonus to my previous post “Oracle Data Integrator & MapR Converged Data Platform: CHECK!“. MapR-DB client APIs can access both HBase tables and MapR-DB tables, it all depends on what you pass to its methods. So in case you need to reverse engineer your MapR-DB tables, […]

Hive, Partitions and Oracle Data Integrator

If you using Oracle Data Integrator (ODI) to load a set of results into a table with partitions and unable to, you’re in the right place. Partitions are good and needed, no need to talk about their benefits here. What I’m going to focus on is how to let ODI use them with a “dirty” […]

Oracle Data Integrator & MapR Converged Data Platform: CHECK!

MapR has their own Hadoop-derived software, a distribution that claims “to provide full data protection, no single points of failure, improved performance, and dramatic ease of use advantages”. For instance, MapR doesn’t rely on regular HDFS we’re all used to, but came up with MapR-FS, which works differently and provides substantial advantages over regular HDFS, […]

MapR-FS Real-Time Transactional Data Ingestion using Oracle GoldenGate

“MapR-FS is a POSIX file system that provides distributed, reliable, high performance, scalable, and full read/write data storage for the MapR Converged Data Platform. MapR-FS supports the HDFS API, fast NFS access, access controls (MapR ACEs), and transparent data compression. MapR-FS includes enterprise-grade features such as block-level mirroring for mission-critical disaster recovery as well as load balancing, […]

Moving Data Across Hadoop Clusters using Oracle Data Integrator

Today I came across this request: “We need to copy our data efficiently between two Hadoop clusters, via ODI. Can we?”. When it comes to ODI, I cannot think of a case where I ever said no, thanks to its modular architecture, flexibility and extensibility. While there is no “official” KM yet shipped with ODI […]
