modin incorrect syntax error on read_sql with oracle

Question

Using modin's implementation of read_sql, I am getting a syntax error. It seems to be due to the aliasing of the count query generated in read_sql.

Am I doing something wrong or is this due to a lack of compatibility with oracle?

Also, note that passing the same arguments to pandas.read_sql() does not cause this error.

import modin.pandas as pd
query = """select distinct col_a, col_b FROM test_table"""
df = pd.read_sql(query, conn)

sqlalchemy.exc.DatabaseError: (cx_Oracle.DatabaseError) ORA-00933: SQL command not properly ended

[SQL: SELECT COUNT(*) FROM (select distinct col_a, col_b FROM test_table) AS _]
