[jira] [Comment Edited] (SOLR-11617) Expose Alias Metadata CRUD in REST API

["Gus Heck (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/SOLR-11617?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16266281#comment-16266281 ]

-----------------------------------------------------------

Patch implementing MODIFYALIAS and returning a "metadata" section along side the existing "aliases" section. One minor quirk is that if you remove all alias metadata from an alias it still shows up with an empty metadata section like this: 

{code:java}
{
  "responseHeader":{
    "status":0,
    "QTime":6},
  "aliases":{
    "name":"test1,test2",
    "name1":"test1,test2"},
  "metadata":{
    "name":{},
    "name1":{"foo":"bar2"}}}
{code}

I'm not sure if that's really such a bad thing though. The metadata section for the alias is of course still removed if the alias is removed.

V2 stuff not yet contemplated...

> SOLR-11487 is adding Java API for metadata on aliases, this task is to expose that functionality to end-users via a REST API.
> Some proposed commands, for initial discussion:
>  - *SETALIASMETA* - upsert, or delete if blank/null/white-space provided.
>  - *GETALIASMETA* - read existing alias metadata
> Given that the parent ticket to this task is going to rely on the alias metadata, and I suspect a user would potentially completely break their time partitioned data configuration by editing system metadata directly, we should either document these commands as "use at your own risk, great power/responsibility etc" or consider protecting some subset of metadata.
