Posted by jh...@apache.org.
[CALCITE-1051] Underflow exception due to scaling IN clause literals (Frankie Bollaert)
Literals in the IN clause value list are scaled during SqlToRel
conversion. When the type of the literal does not have a scale set,
as happens with a java.lang.Integer, the default value of the
type.scale is chosen, which is Integer.MIN_VALUE. Scaling to this
value causes an underflow.

+{: #v1-6-0}
+
+As usual in this release, there are new SQL features, improvements to
+planning rules and Avatica, and lots of bug fixes. We'll spotlight a
+couple of features make it easier to handle complex queries.
+
+[<a href="https://issues.apache.org/jira/browse/CALCITE-816">CALCITE-816</a>]
+allows you to represent sub-queries (`EXISTS`, `IN` and scalar) as
+`RexSubQuery`, a kind of expression in the relational algebra. Until
+now, the sql-to-rel converter was burdened with expanding sub-queries,
+and people creating relational algebra directly (or via RelBuilder)
+could only create 'flat' relational expressions. Now we have planner
+rules to expand and de-correlate sub-queries.
+
+Metadata is the fuel that powers query planning. It includes
+traditional query-planning statistics such as cost and row-count
+estimates, but also information such as which columns form unique
+keys, unique and what predicates are known to apply to a relational
+expression's output rows. From the predicates we can deduce which
+columns are constant, and following
+[<a href="https://issues.apache.org/jira/browse/CALCITE-1023">CALCITE-1023</a>]
+we can now remove constant columns from `GROUP BY` keys.
+
+Metadata is often computed recursively, and it is hard to safely and
+efficiently calculate metadata on a graph of `RelNode`s that is large,
+frequently cyclic, and constantly changing.
+[<a href="https://issues.apache.org/jira/browse/CALCITE-794">CALCITE-794</a>]
+introduces a context to each metadata call. That context can detect
+cyclic metadata calls and produce a safe answer to the metadata
+request. It will also allow us to add finer-grained caching and
+further tune the metadata layer.
