SLONIK SET ADD SEQUENCEConfiguration and Action commSLONIK SET ADD SEQUENCE(7)NAME
SET ADD SEQUENCE - Add a sequence to a Slony-I replication set
SYNOPSIS
SET ADD SEQUENCE (options);
DESCRIPTION
Add an existing user sequence to a replication set. The set cannot cur‐
rently be subscribed by any other node - that functionality is sup‐
ported by the SLONIK MERGE SET(7) command.
SET ID = ival
ID of the set to which the sequence is to be added.
ORIGIN = ival
Origin node for the set. (optional)
ID = ival
Unique ID of the sequence.
Note: Note that this ID needs to be unique across sequences
throughout the cluster; the numbering of tables is separate, so
you might have a table with ID 20 and a sequence with ID 20, and
they would be recognized as separate.
This parameter is optional. If this parameter is omitted then slonik
will check every node that it can connect to and find the highest table
id being used across all nodes.
FULLY QUALIFIED NAME = 'string'
The full sequence name including schema name. If SEQUENCES is
specified then FULLY QUALIFIED NAME should be omitted.
SEQUENCES = 'string'
A POSIX regular expression that matches to the sequences that
should be added to the replication set. This regular expression
is passed to postgresql for evaluation on the set origin against
fully qualified sequence names. This parameter is optional. If
FULLY QUALIFIED NAME is omitted then SEQUENCES must be speci‐
fied.
COMMENT = 'string'
A descriptive text added to the sequence entry.
This uses setaddsequence(integer,integer,text,text).
EXAMPLE
SET ADD SEQUENCE (
SET ID = 1,
ORIGIN = 1,
ID = 20,
FULLY QUALIFIED NAME = 'public.tracker_ticket_id_seq',
COMMENT = 'Support ticket ID sequence'
);
or
SET ADD SEQUENCE(
SET ID=1,
SEQUENCES='public.tracker_ticket_id_seq'
);
LOCKING BEHAVIOUR
No application-visible locking should take place.
SLONIK EVENT CONFIRMATION BEHAVIOUR
Slonik waits for the command submitted to the previous event node to be
confirmed on the specified event node before submitting this command.
VERSION INFORMATION
