@ -49,17 +49,18 @@ class StreamIdGenerator(object):
all ids less than or equal to it have completed. This handles the fact that
persistence of events can complete out of order.
:param connection db_conn: A database connection to use to fetch the
initial value of the generator from.
:param str table: A database table to read the initial value of the id
generator from.
:param str column: The column of the database table to read the initial
value from the id generator from.
:param list extra_tables: List of pairs of database tables and columns to
use to source the initial value of the generator from. The value with
the largest magnitude is used.
:param int step: which direction the stream ids grow in. +1 to grow
upwards, -1 to grow downwards.
Args:
db_conn(connection): A database connection to use to fetch the
initial value of the generator from.

column(str): The column of the database table to read the initial
value from the id generator from.
extra_tables(list): List of pairs of database tables and columns to
use to source the initial value of the generator from. The value
with the largest magnitude is used.
step(int): which direction the stream ids grow in. +1 to grow
upwards, -1 to grow downwards.
Usage:
with stream_id_gen.get_next() as stream_id:
