SOLR-15456: Get field type info from luke for custom fields instead of
defaulting to String in Parallel SQL (#2524)
> Solr SQL metrics for field with custom field type defaults to String instead
> of using the correct numeric type

> Project: Solr
> Issue Type: Bug
> Components: Parallel SQL
> Reporter: Timothy Potter

> I have a simple "stats" query (from SolrTable) that requests the min / max of
> an integer field, but that field is declared in the schema using a custom
> field type, such as:
> {code}
> <fieldType name="integer" class="solr.TrieIntField" .../>
> <field name="myIntField" type="integer" .../>
> {code}
> The switch at
> https://github.com/apache/solr/blob/main/solr/core/src/java/org/apache/solr/handler/sql/SolrSchema.java#L144
> causes the "type" for this field to be {{String}} which results in some
> weird output for this query:
> {code}
> SELECT min(myIntField), max(myIntField) from table
> {code}
> Results:
> {code}
> {
> "result-set":{
> "docs":[{
> "EXPR$0":"2.0210507E7",
> "EXPR$1":"2.0210605E7"}
> ,{
> "EOF":true,
> "RESPONSE_TIME":8846}]}}
> {code}
> Since we're querying {{/luke}} already to get schema info, we might as well
> use the field type info vs. defaulting to String
