Select with concat function not working in 8.4.1
Greetings.
In upgrading to solr 8.4.1, the following streaming expression is not working for me:
select(
cartesianProduct(
tuple(k1="1", k2=array(a)),
k2, productSort="k1 asc"),
"k1”,
concat(fields="k1",delim=",",as="node") )
Returning “"Invalid expression select(cartesianProduct(tuple(k1=1,k2=array(a)),k2,productSort=\”k1 asc\"),\"k1\",concat(fields=k1,delim=\",\",as=node)) - unknown operands found"”.
But it works fine in 8.2.0.
Am I missing something, or should a jira ticket be opened for this?
Thank you
Kind regards,
Guilherme Nunes

The concat function was changed to an evaluator. An example of the new
syntax is here:
https://github.com/apache/lucene-solr/blob/visual-guide/solr/solr-ref-guide/src/loading.adoc#unique-ids
Sorry for confusion the language should be settling down now with very of
these types of changes happening going forward.

Greetings.
A follow-up to the below with my findings.
The problem seems to be that the binding of “concat” on the StreamFactory.functionNames maps to ConcatEvaluator in 8.4.1, while in 8.2 it mapped to ConcatOperation.
The mapping is defined in the file Lang.java
Branch_8_4:
Branch_8_2:
The workaround to achieve a functioning move from 8.2 to 8.4.1, in our case, was to override the mapping of concat in the solrconfig.xml with
<expressible name="concat" class=“org.apache.solr.client.solrj.io.ops.ConcatOperation” />
