Hi Cristian!

A HDFS cache store [1] looks interesting, and given the append-only nature of HDFS, I'd say probably the SoftIndex is better to look at than the SingleFile store since it employs some techniques of append only plus eventual compactations.
It'd be interesting to have a design document so that we can have a starting point; we usually publish such designs at [2].

Cheers,
Gustavo

Hello folks - I would like to implement for my own project a custom cache store for Infinispan using HDFS and using as base line one of the already implemented file stores - SoftIndex and SingleFile. 
I thought it would be beneficiary if I start and do it directly as contribution to the Infinispan code base, is someone interested to take on this subject and we start brainstorming about how should this task being approached to be sure it gets done smooth, accordingly to the project's community house rules so we don't encounter hassle at the point when we can look at merging in the baseline, avoid potentially double work for same feature etc. 

Kind regards

P.S I went already trough http://infinispan.org/docs/8.2.x/contributing/contributing.html
so theoretically I can just start and place a pull request on GitHub but I wanted to be sure you guys are also aware of this plan so we keep in sync and all opinions are taken in consideration and addressed.
