Hi Mich, Yes, Alluxio is commonly used to cache and share Spark RDDs and DataFrames among different applications and contexts. The data typically stays in memory, but with Alluxio's tiered storage, the "colder" data can be evicted out to other medium, like SSDs and HDDs. Here is a blog post discussing Spark RDDs and Alluxio: https://www.alluxio.com/blog/effective-spark-rdds-with-alluxio
Also, Alluxio also has the concept of an "Under filesystem", which can help you access your existing data across different storage systems. Here is more information about the unified namespace abilities: http://www.alluxio.org/docs/master/en/Unified-and-Transparent-Namespace.html Hope that helps, Gene On Thu, Oct 27, 2016 at 3:39 AM, Mich Talebzadeh <mich.talebza...@gmail.com> wrote: > Thanks Chanh, > > Can it share RDDs. > > Personally I have not used either Alluxio or Ignite. > > > 1.
