> Adding a text type field "cat6" in AggregationTest.java, I've run the
> following SQL:
> {code:java}
> @Test void testGroupTextField() {
> CalciteAssert.that()
> .with(newConnectionFactory())
> .query("select cat6 from view group by cat6")
> .returns("EXPR$0=1\n");
> }
> {code}
> and I get such exception:
> {code:java}
> {"error":{"root_cause":[{"type":"illegal_argument_exception","reason":"Text
> fields are not optimised for operations that require per-document field data
> like aggregations and sorting, so these operations are disabled by default.
> Please use a keyword field instead. Alternatively, set fielddata=true on
> [cat6] in order to load field data by uninverting the inverted index. Note
> that this can use significant memory."}],......(useless message),"status":400}
> {code}
> As Elasticsearch does supports grouping text field(memory consumed), it's
> better to show SQL users how to implement it in Calcite by enriching ES's
> test cases.
