Description

Package store is a storage managed by Solr that holds the package artifacts. This is replicated across nodes.

Design is here: https://docs.google.com/document/d/15b3m3i3NFDKbhkhX_BN0MgvPGZaBj34TKNF2-UNC3U8/edit?ts=5d86a8ad#

The package store is powered by an underlying filestore. This filestore is a fully replicated p2p filesystem storage for artifacts.

The APIs are as follows

# add a file
POST  /api/cluster/files/path/to/file.jar

#retrieve a file
GET /api/cluster/files/path/to/file.jar

#list files in the /path/to directory
GET /api/cluster/files/path/to

#GET meta info of the jar
GET /api/cluster/files/path/to/file.jar?meta=true

This store keeps 2 files per file

1. The actual file say myplugin.jar
2. A metadata file .myplugin.jar.json in the same directory

The contenbts of the metadata file is

{
"sha512" : "<sha512-of the file>"
"sig": {
"<key-name>" :"<signature>"
}}
