You are right, removing the collations could only workaround what causes us to
find the issue on multi-sort. Maybe we'd better not to remove them (at least
currently) since they provide a way to easily test against composite trait.

Hello SQL experts,
Does Calcite support the ARRAY subquery expression[1]? It looks liked based
on SqlArrayQueryConstructor, it does [2]? Do folks know if this is standard
SQL and supported in very many databases?
The use case is to simplify queries that process arrays. Instead of doing a

Exactly.
Of course no one knows how it should work, however making
"RelTraitSet#simplify" a no-op does heal certain cases,

I am afraid even removing Values collation enumeration won't actually give it a
quick fix,
because Multi-sorted table, if there is, might still encounter the same issue

Hi,
So I've trying to connect Calcite with Apache Phoenix. Code given below:
*public Frameworks.ConfigBuilder configPhoenix() {*
* SchemaPlus rootSchema = Frameworks.createRootSchema(true);*
* DataSource dataSource =
JdbcSchema.dataSource("jdbc:phoenix:::/hbase-unsecure",
"org.apache.phoenix.jdbc
Dear all,
I have setup calcite to use postgres as a datasource. Right now I am
running into an out of memory exception while executing the following
query: "select * from table order by id limit 10". Checking the log of
postgres it seems like calcite is wanting to first load all data into the
memo
Hi,
I am a engineer at Flipkart, we are building SQL over our stream processing
platform using Calcite.
I am finding it hard to develop intuition for abstractions and entities in
Apache Calcite, is there a book or documentation that walks through them?
I would love if I could chat with one of you
If we minimize the issue scope to Calcite itself, I think the 3 JIRA
tickets: CALCITE-2010, CALCITE-2593, CALCITE-2764 that Haisheng has
listed (thanks, Haisheng!) are all related to the multi-sorted
EnumerableValue more or less. An it looks like if we want to get these
problems fixed quickly w
