Description:
Synchronize the nodes.
Syntax:
sync(h,p;z)
Note:
The function synchronizes file p in data zone z on the current node onto node sequence h. If there isn’t a data zone z in h, ignore the sync action; if there is a newer file p in h, sync the newer one onto all the other nodes.
Parameters:
|
h |
A sequence of nodes |
|
p |
The file directory in the zone list on the nodes; all files will be synced if it is absent |
|
z |
A data zone named after an integer. The parameter is a sequence when there are multiple zones. It denotes the main directory when not provided |
Example:
|
|
A |
|
|
1 |
=sync(["192.168.1.100:8081","192.168.1.101:8283"] |
Sync all files in the main directory on the current node onto node "192.168.1.100:8081" and node "192.168.1.101:8283" |
|
2 |
=sync(["192.168.1.100:8081","192.168.1.101:8283"],"f1") |
Sync folder "f1" in the main directory on the current node onto node "192.168.1.100:8081" and node "192.168.1.101:8283" |
|
3 |
=sync(["192.168.1.100:8081","192.168.1.101:8283","192.168.1.102:8081"];[1,2,3]) |
Sync all files in data zones 1, 2, 3 on the current node onto the corresponding data zones on node "192.168.1.100:8081", node "192.168.1.101:8283" and node "192.168.1.102:8081"; as the third node doesn’t have data zone 3, just skip the sync to this zone |
|
=sync(["192.168.1.100:8081","192.168.1.101:8283"],"t1";1) |
Sync folder "f1" in data zone 1 on the current node onto data zone 1 on both node "192.168.1.100:8081" and node "192.168.1.101:8283" |
