# 8.21. Table: `sl_setsync`

SYNC information

Structure of `sl_setsync`

`ssy_setid`

  `integer` `PRIMARY KEY` `REFERENCES` sl_set

  ID number of the replication set

`ssy_origin`

  `integer` `REFERENCES` sl_node

  ID number of the node

`ssy_seqno`

  `bigint`

  Slony-I sequence number

`ssy_snapshot`

  `txid_snapshot`

  TXID in provider system seen by the event

`ssy_action_list`

  `text`

  action list used during the subscription process. At the time a subscriber copies over data from the origin, it sees all tables in a state somewhere between two SYNC events. Therefore this list must contains all log_actionseqs that are visible at that time, whose operations have therefore already been included in the data copied at the time the initial data copy is done. Those actions may therefore be filtered out of the first SYNC done after subscribing.
