Sets the last-delivered ID of a consumer group.
XGROUP
SETID key group
<id | $>
[ENTRIESREAD entries-read]
Set the last delivered ID for a consumer group.
Normally, a consumer group’s last delivered ID is set when the group
is created with XGROUP CREATE. The
XGROUP SETID command allows modifying the group’s last
delivered ID, without having to delete and recreate the group. For
instance if you want the consumers in a consumer group to re-process all
the messages in a stream, you may want to set its next ID to 0:
XGROUP SETID mystream mygroup 0The optional entries_read argument can be specified to
enable consumer group lag tracking for an arbitrary ID. An arbitrary ID
is any ID that isn’t the ID of the stream’s first entry, its last entry
or the zero (“0-0”) ID. This can be useful you know exactly how many
entries are between the arbitrary ID (excluding it) and the stream’s
last entry. In such cases, the entries_read can be set to
the stream’s entries_added subtracted with the number of
entries.
