+.. note::
+
+   **TIMESTAMP data type not supported in RowFilter FilterExpression**
+
+   AWS Lake Formation Data Cells Filters do **not** support ``TIMESTAMP`` columns
+   in the ``RowFilter.FilterExpression`` predicate.  Attempting to use a timestamp
+   column in the filter expression (e.g.
+   ``"timestamp" > '2026-05-01 00:00:00'``) will return::
+
+       InvalidInputException: TIMESTAMP data type not supported for row level filter predicate.
+
+   **Tested expressions that all fail:**
+
+   - ``"timestamp" > '2026-05-01 00:00:00'``
+   - ``timestamp > date_sub(current_date(), 30)``
+   - ``timestamp > cast(now() - interval 30 days as timestamp)``
+   - ``timestamp >= current_timestamp - interval '30' day``
+   - ``timestamp >= current_date() - INTERVAL 30 DAYS``
+
+   **Workarounds:**
+
+   - Filter on a *derived string column* (e.g., a partition column formatted as
+     ``YYYY-MM-DD``) using string comparison instead of a native timestamp column.
+   - Pre-process the table to store the date portion as a ``STRING`` or ``DATE``
+     column and apply the row filter on that column.
+   - Use column-level security (``ColumnNames`` / ``ExcludedColumnNames``) to
+     restrict access to the timestamp column entirely rather than filtering by
+     value.

+   `Data Cells Filters documentation <https://docs.aws.amazon.com/lake-formation/latest/dg/data-filtering.html>`__.
