Analytical and operational access patterns are very different and until now the Hadoop ecosystem has not had a single storage engine that could support both. As a result, engineers have been forced to implement complex architectures that stitch multiple systems together in order to provide these capabilities. On one hand immutable data on HDFS offers superior analytic performance, while mutable data in Apache HBase is best for operational workloads. Apache Kudu bridges this gap.
Kudu’s architecture is shaped towards the ability to provide very good analytical performance,
