the reason why JOIN works is because of the Calcite framework. The parallel
sql features leverages Calcite, which implements all the sql features, all
you need is to provide the way for calcite to get the collection/table, in
solr this is done by the SolrTable.java (package
org.apache.solr.handler.
There isn't any real support for joins in Parallel SQL currently. I'm
surprised that you're having some success doing them. Can you provide a
sample SQL join that is working for you?

Hi,
Although there is no trace of join functionality in the official Solr
documentation
(https://lucene.apache.org/solr/guide/7_4/parallel-sql-interface.html),
joining in parallel sql works in practice. It only works if the field is
not a multivalued field. For my project it would be fantastic if
