Return a pg8000 connection from a Glue Catalog Connection.


You MUST pass a connection OR secret_id. Here is an example of the secret structure in Secrets Manager: { “host”:””, “username”:”test”, “password”:”test”, “engine”:”postgresql”, “port”:”3306”, “dbname”: “mydb” # Optional }

  • connection (str, optional) – Glue Catalog Connection name.

  • dbname (str, optional) – Optional database name to overwrite the stored one.

  • boto3_session (boto3.Session(), optional) – Boto3 Session. The default boto3 session will be used if boto3_session receive None.

  • ssl_context (bool or SSLContext, optional) – This governs SSL encryption for TCP/IP sockets. This parameter is forward to pg8000.

  • timeout (int, optional) – This is the time in seconds before the connection to the server will time out. The default is None which means no timeout. This parameter is forward to pg8000.

  • tcp_keepalive (bool) – If True then use TCP keepalive. The default is True. This parameter is forward to pg8000.
