• Name Calcite's own spatial classes on the model class allowlist, so fun=spatial works out of the box

• Flaky: correlated EXISTS over UNCOLLECT with top-down decorrelation trips a HepPlanner assertion on arm64

• JSON_VALUE: the ON EMPTY clause appears to be parsed and ignored (upstream Calcite)

• JSON_VALUE: a RETURNING type mismatch bypasses ON ERROR and raises a raw cast failure (upstream Calcite)

• The catalog shows tables only: no functions, no procedures, no types

• INSERT, UPDATE and DELETE against an ADO table fail to plan

• A cross-source join pulls both sides; the smaller one could be shipped to the larger

• Two schemas over one database join in memory, because the convention is per schema

• AdoTable reports no statistics, so every table has 100 rows and no keys

  ikvmnet/calcite-dotnet#113 · Filter by author wasabii opened on Sep 8, 2026

• The converters out of AdoConvention cost full price, and two joins are left in memory because of it
