Chris M. Hostetter commented on SOLR-17862:
-------------------------------------------
It's easy to see that changes to one collection impact other collections.
Setup two collections using the same configset:
{noformat}
$ ./solr/packaging/build/dev/bin/solr start -e cloud --no-prompt
...
$ curl
'http://localhost:8983/solr/admin/collections?action=CREATE&name=xxxx&collection.configName=gettingstarted&numShards=1'\
...
$ curl 'http://localhost:8983/api/collections/xxxx/config/overlay'
{
"responseHeader":{
"status":0,
"QTime":3
},
"overlay":{
"znodeVersion":-1
}
}
$ curl 'http://localhost:8983/api/collections/gettingstarted/config/overlay'
{
"responseHeader":{
"status":0,
"QTime":3
},
"overlay":{
"znodeVersion":-1
}
}
{noformat}
Then attempt to modify one collection:
{noformat}
$ curl -X POST -H 'Content-type: application/json' -d
'{"set-property":{"updateHandler.autoCommit.maxTime":12345}}'
http://localhost:8983/api/collections/xxxx/config
...
$ curl 'http://localhost:8983/api/collections/xxxx/config/overlay'
{
"responseHeader":{
"status":0,
"QTime":1
},
"overlay":{
"znodeVersion":0,
"props":{
"updateHandler":{
"autoCommit":{
"maxTime":12345
}
}
}
}
}
$ curl 'http://localhost:8983/api/collections/gettingstarted/config/overlay'
{
"responseHeader":{
"status":0,
"QTime":0
},
"overlay":{
"znodeVersion":0,
"props":{
"updateHandler":{
"autoCommit":{
"maxTime":12345
}
}
}
}
}
{noformat}

> Key: SOLR-17862
> URL: https://issues.apache.org/jira/browse/SOLR-17862
> Project: Solr
> Issue Type: Bug
> Reporter: Chris M. Hostetter
> Priority: Major
>
> The "Config API" uses a URL path prefix of
> {{/api/collections/<<COLLECTION_NAME>>/config}} and [has documentation that
> says|https://solr.apache.org/guide/solr/latest/configuration-guide/config-api.html]...
> {quote}
> All Config API endpoints are collection-specific, meaning this API can
> inspect or modify the configuration for a single collection at a time.
> {quote}
> ...but this is a lie. Using the Config API to modify any aspect of a
> collection actually modifies the {{configoverlay.json}} in the configset, and
> impacts all collections using that configset.
> ----
> * The "Config API" should be changed to use some new a URL path prefix that
> is specific to the name of the configset (Example:
> {{/api/configset-props/<<CONFIGSET_NAME>>/}})
> * The Existing {{/api/collections/<<COLLECTION_NAME>>/config}} URL should be
> deprecated
> * Documentation should be updated accordingly
