7. List Containers in Merge mode
Prefix to indicate the name of the swift system
is given a container. Merged
GET /merged/v1.0/AUTH_test
sw0: sw0: sw0:
sw0:Cont0 Cont Cont Cont
sw0:Cont1 0 1 2
sw0:Cont2
sw1: sw1: sw1:

sw1:Cont2
• Corresponds to the
output format plain text, Swift0 Swift1
json, the XML
Cont Cont Cont Cont Cont Cont
• Corresponds to the
0 1 2 0 1 2
parameter "marker"

8. List Objects in Merge mode
Receive a container with a prefix, which returns
a list of objects in the container specified on the Merged
swift system indicated by the prefix
sw0: sw0: sw0:

9. Operate Container in Merge mode
Receive a container with a prefix, on the swift
system indicated by prefix, to manipulate the
Merged
container

10. Operate Object in Merge mode
Receive a container with a prefix, to manipulate
the objects in the container specified on the swift Merged
system indicated by the prefix.
sw0: sw0: sw0:

11. Copy Object in Merge mode
Copy between containers of the same
prefix is the same as "Copy Object" normal. Merged
sw0: sw0: sw0:
Cont Cont Cont
COPY /merged/v1.0/AUTH_test/sw0:Cont2/obj0 0 1 2
X-Copy-From: /sw0:Cont1/obj0

COPY

12. Copy Object in Merge mode
In the copy of containers between different Swift0
prefix, make a GET of objects inside dispatcher, Cont Cont Cont
perform the PUT to another system. 0 1 2
obj
GET
COPY /merged/v1.0/AUTH_test/sw1:Cont2/obj0
X-Copy-From: /sw0:Cont1/obj0
Content-Length: 0 dispatcher
If the object that exceeds a 5G, the upload
PUT
process is performed internally divided.

Cont Cont Cont
0 1 2 obj
