+This directory contains fixtures for testing different data types support.
+
+SQL files contain table structure and sample data, other files contain raw
+responses for different combination of options (with or without Arrow support enabled,
+with or without Arrow native types). In all cases, data should be decoded in
+exactly the same way.
+
+Known issues:
+
+- with Arrow disabled _or_ with Arrow native types disabled:
+  - date values are not properly serialized in nested structures, so complex types cannot be JSON-decoded;
+    therefore this case is not represented in this test set
+  - any non-string type used as map key is not properly serialized and cannot be JSON-decoded;
+    therefore this case is not represented in this test set
