Rework Working with NoSQL Technologies to clarify which stores are supported by Spring Data

[wilkinsona]

In https://docs.spring.io/spring-boot/docs/2.5.x/reference/html/features.html#features.nosql, below the bulleted list, there's the following paragraph:

Spring Boot provides auto-configuration for Redis, MongoDB, Neo4j, Solr, Elasticsearch, Cassandra, Couchbase, LDAP and InfluxDB. You can make use of the other projects, but you must configure them yourself. Refer to the appropriate reference documentation at spring.io/projects/spring-data.

Solr and InfluxDB are no longer supported and should be removed. It might also be worth sorting alphabetically the stores in this paragraph and in the preceding list. Alternatively, the list and paragraph could be combined into a two-column table with the first column containing the bulleted list's existing links and the second linking to the relevant section of Boot's documentation where applicable.

We still have SolrAutoConfiguration in and SolrHealthIndicator in the codebase.

And InfluxDbAutoConfiguration.

Thanks, Phil. I was confused by "refer to the appropriate reference documentation at spring.io/projects/spring-data". Spring Data used to have a Solr module but no longer does. It's never supported InfluxDB.

I think we still need to do something here, perhaps reworking things to separate the Spring Data-supported stores from the others.

@wilkinsona, I can change that paragraph. Please tell me if you want me to remove Solr and InfluxDB plus sort alphabetically? Or should I change more?

Thanks for the offer, @viktorardelean. We’ve found that this sort of documentation update often results in a contributor essentially copying and pasting a suggestion that we make into a pull request. That’s not satisfying for us or, more importantly, for the contributor. As such, we prefer to handle this sort of documentation update ourselves. Thanks anyway.
