> 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
> {code:java}
> # 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
> {code}
> This store keeps 2 files per file
> # The actual file say {{myplugin.jar}}
> # A metadata file {{.myplugin.jar.json}} in the same directory
> The contenbts of the metadata file is
> {code:json}
> {
> "sha512" : "<sha512-of the file>"
> "sig": {
> "<key-name>" :"<signature>"
> }}
> {code}
