Shalin Shekhar Mangar updated SOLR-6021:
----------------------------------------
Attachment: SOLR-6021.patch
Changes
# Added a getter for coreConfigService in CoreContainer
# Overseer reads config/schema to get the unique key field name if router is
not implicit and router.field is not specified.
# Added a test in TestCollection API
I initially wanted to do this in OverseerCollectionProcessor but then you can
skip that completely if you're creating collections through the core admin API.
SolrJ doesn't need any changes because if a router.field is configured, the
"idField" and it's value is not used at all.
> Always persist router.field in cluster state so CloudSolrServer can route
> documents correctly

> CloudSolrServer has idField as "id" which is used for hashing and
> distributing documents. There is a setter to change it as well.
> IMO, we should use the correct uniqueKey automatically. I propose that we
> start storing router.field always in cluster state and set it to the
> uniqueKey field name by default. Then CloudSolrServer would not need to
> assume an "id" field by default.
