Subject [Incubator Wiki] Update of "PistachioProposal" by GavinLi
Date Mon, 29 Jun 2015 18:54:36 GMT
Dear Wiki user,

You have subscribed to a wiki page or wiki category on "Incubator Wiki" for change notification.

The "PistachioProposal" page has been changed by GavinLi:
https://wiki.apache.org/incubator/PistachioProposal?action=diff&rev1=5&rev2=6

  
  As a key value store system Pistachio is unique in terms of low latency access with fault
tolerance and consistency guarantee. The reliability, scalability, fault tolerance and performance
has been well proven in global large scale revenue supporting production system in Yahoo.
  
- As a distributed computation system, it’s a different model from the common models like
Hadoop that the compute layer is introduced on top of the storage layer natively and naturally
to optimize the data locality of computation. Comparing with the traditional model like Hadoop
the computation can be distributed to storage partition to avoid data transfer in the shuffling
to achieve much better throughput.
+ As a distributed computation system, it’s a different model from the common models like
Hadoop that the compute layer is introduced on top of the storage layer natively and naturally
to optimize the data locality of computation. Comparing with the Hadoop model, intermediate
results can always be stored in a partitioned way and the computation can be distributed to
storage partitions to avoid data transfer in the shuffling phase between map reduce jobs in
Hadoop to achieve much better throughput.
  
  Operating the project in “apache way” greatly aligns with the long-term vision of this
project and can greatly help the development of the community.
