------------------------------------------
Summary: Derive rowCount statistics for tables in ReflectiveSchema
that are based on arrays/collections
Key: CALCITE-3661
URL: https://issues.apache.org/jira/browse/CALCITE-3661
Project: Calcite
Issue Type: Bug
Components: core
Affects Versions: 1.21.0
Reporter: Vladimir Sitnikov
ReflectiveSchema is used quite common in Calcite tests, however, it misses
statistics, so every reflective table is assumed to have 100 rows which makes
it hard to understand if the optimizer is making reasonable decisions (e.g.
join ordering).
