Description
16+
-----------
17+
18+
Commits the synchronization operation to the destination cluster.
19+
20+
Requirements
21+
------------
22+
23+
Before using the ``commit`` endpoint:
24+
25+
- Stop your application. This ensures that no additional writes occur on
26+
the source cluster.
27+
28+
- Use the :ref:`progress <c2c-api-progress>` endpoint to confirm the
29+
following values:
30+
31+
- ``state: "RUNNING"``
32+
- ``canCommit: true``
33+
- ``lagTimeSeconds`` is near ``0`` (*Recommended, but not required*)
34+
35+
.. note:: lagTimeSeconds
36+
37+
``lagTimeSeconds`` indicates the time between the last applied
38+
event and time of the current latest event. When you send a
39+
``commit`` request, {+c2c-product-name+} enters the
40+
``COMMITTING`` state for the amount of seconds reported by
41+
``lagTimeSeconds``, and then transitions to the ``COMMITTED``
42+
state.
43+
44+
When ``lagTimeSeconds`` is ``0``, the source and destination
45+
clusters are in a consistent state.
46+
47+
Request
48+
-------

50+
.. code-block:: http

Request Body Parameters

63+

Example
65+
-------
66+
67+
The following example commits the synchronization operation to the
68+
destination cluster.
69+
70+
Confirm that the Synchronization is Ready
71+
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
72+
73+
Before sending a request to the ``commit`` endpoint, use the
74+
:ref:`progress <c2c-api-progress>` endpoint to confirm that the
75+
synchronization is ready to be committed.
76+
77+
Request
78+
```````
79+
80+
.. literalinclude:: /includes/api/requests/progress.sh
81+

83+
Response
84+
````````

86+
.. literalinclude:: /includes/api/responses/progress.json
87+
:language: shell
88+
:emphasize-lines: 5
89+
90+
The ``progress`` endpoint returned ``"canCommit":true``, which means
91+
that the ``commit`` request can run successfully.
92+
93+
Send the Commit Request
94+
~~~~~~~~~~~~~~~~~~~~~~~
95+
96+
The following command sends a request to the ``commit`` endpoint:
97+
98+
Request
99+
```````
100+
101+
.. literalinclude:: /includes/api/requests/commit.sh
102+
:language: shell
103+
104+
Response
105+
````````
106+
107+
.. literalinclude:: /includes/api/responses/success.json
108+
:language: json
109+
110+
Behavior
111+
--------
112+
113+
If the ``commit`` request is successful, {+c2c-product-name+} enters the
114+
``COMMITTING`` state, then automatically transitions to the
115+
``COMMITTED`` state.
