The "MnemonicProposal" page has been changed by YanpingWang1:

  All developers are paid by their employers to contribute to this project. We welcome all
others to contribute to this project after it is open sourced.
  ==== Relationships with Other Apache Product ====
+ Relationship with Apache™ Arrow: 
+ Arrow's columnar data layout allows great use of CPU caches & SIMD. It places all data
that relevant to a column operation in a compact format in memory. 
+ Mnemonic directly puts the whole business object graphs on external heterogeneous storage
media, e.g. off-heap, SSD. It is not necessary to normalize the structures of object graphs
for caching, checkpoint or storing. It doesn’t require developers to normalize their data
object graphs. Mnemonic applications can avoid indexing & join datasets compared to traditional
+ Mnemonic can leverage Arrow to transparently re-layout qualified data objects or create
special containers that is able to efficiently hold those data records in columnar form as
one of major performance optimization constructs.
  Mnemonic can be integrated into various Big Data and Cloud frameworks and applications.
  We are currently working on several Apache projects with Mnemonic:
- For Apache Spark™ we integrated Mnemonic to improve: 
+ For Apache Spark™ we are integrating Mnemonic to improve: 
  a) Local checkpoints
  b) Memory management for caching
  c) Persistent memory datasets input
