Thanks, that&#x27;s helpful. We picked ES for several reasons. We&#x27;re not a Java shop, and the Hadoop ecosystem is heavily biased towards JVM languages.<p>Secondly, ES is easy to deploy and manage. Being on the JVM, it admittedly has a considerable RAM footprint, but at least it&#x27;s just one daemon per node. With anything related to Hadoop, it seems you have this cascade of JVM processes that inevitably need management. And lots and lots of RAM.<p>Thirdly, as you point out it&#x27;s easy to do real-time writes.<p>I do like the fact that Kudu is C++.
