Ishan Chattopadhyaya updated SOLR-13722:
----------------------------------------
Summary: Package Management APIs (was: A cluster-wide blob upload package
option & avoid remote url)
> Package Management APIs
> -----------------------
>
> Key: SOLR-13722
> URL: https://issues.apache.org/jira/browse/SOLR-13722
> Project: Solr
> Issue Type: Sub-task
> Security Level: Public(Default Security Level. Issues are Public)
> Reporter: Noble Paul
> Assignee: Noble Paul
> Priority: Major
> Labels: package
>
> This ticket totally eliminates the need for an external service to host the
> jars. So a url will no longer be required. An external URL leads to
> unreliability because the service may go offline or it can be DDoSed if/when
> too many requests are sent to them
>
>
> Add a jar to cluster as follows
> {code:java}
> curl -X POST -H 'Content-Type: application/octet-stream' --data-binary
> @myjar.jar http://localhost:8983/api/cluster/blob
> {code}
> This does the following operations
> * Upload this jar to all the live nodes in the system
> * The name of the file is the {{sha256}} of the file/payload
> * The blob is agnostic of the content of the file/payload
> h2. How it works?
> A blob that is POSTed to the {{/api/cluster/blob}} end point is persisted
> locally & all nodes are instructed to download it from this node or from any
> other available node. If a node comes up later, it can query other nodes in
> the system and download the blobs as required
> h2. {{add-package}} command
> {code:java}
> curl -X POST -H 'Content-type:application/json' --data-binary '{
> "add-package": {
> "name": "my-package" ,
> "sha256":"<the-sha256>"
> }}' http://localhost:8983/api/cluster
> {code}
> The {{sha256}} is the same as the file name. It gets hold of the jar using
> the following steps
> * check the local file system for the blob
> * If not available locally, query other live nodes if they have the blob
> (one by one)
> * if a node has it , it's downloaded and persisted to it's local {{blob}} dir
> h2. Security
> The blob upload does not check for the content of the payload and it does not
> verify the file. However, the {{add-package}} , {{update-package}} commands
> check for the signatures (if enabled) .
> The size of the file is limited to 5MB,to avoid (OOM). This can be changed
> using a system property {{runtime.lib.size}} .
