Hello:
SQLAlchemnt 0.6.5 - in stderr log we continuously see the following
warning logged. My understanding is this is due to IN () generated
with EMPTY sequence.
However on turning on SQL Alchemny Log, I do not find ant statement
that has where clause with EMPTY IN sequence for predicate
suspiciousevents.rule_id. Any suggestions how to find due to which
session query this warning is coming?

sqlalchemy/sql/expression.py:1660: SAWarning: The IN-predicate on
"suspiciousevents.rule_id" was invoked with an empty sequence. This
results in a contradiction, which nonetheless can be expensive to
evaluate. Consider alternative strategies for improved performance.
return self._in_impl(operators.in_op, operators.notin_op, other)
