Examples

Sync items in the key value store with S3 object

Assume that the following key-value pairs exist in the KeyValueStore cf-kvs-sample.

+-------+---------+
| KEY   | VALUE   |
+-------+---------+
| key-1 | value-1 |
| key-2 | value-2 |
| key-3 | value-3 |
+-------+---------+

Consider synchronizing this KeyValueStore with the data of the following S3 object named data.json.

{
  "data": [
    {"key": "key-1", "value": "v 1"},
    {"key": "key-2", "value": "value-2"},
    {"key": "key-4", "value": "v 4"}
  ]
}

You can check the changes in the KeyValueStore by synchronizing it with data.json using the following command.

$ cfkvs kvs sync \
--kvs-name='cf-kvs-sample' \
--bucket="${YOUR_BUCKET_NAME}" \
--key='data.json'

[ADDED] Following items will be added.
+---+-------+-------+
| # | KEY   | VALUE |
+---+-------+-------+
| 1 | key-4 | v 4   |
+---+-------+-------+

[UPDATED] Following items will be updated.
+---+-------+--------------+-------------+
| # | KEY   | BEFORE VALUE | AFTER VALUE |
+---+-------+--------------+-------------+
| 1 | key-1 | value-1      | v 1         |
+---+-------+--------------+-------------+

[DELETED] No items will be deleted.

If you want to delete keys that do not exist in data.json, add the --delete flag.

$ cfkvs kvs sync \
--name='cf-kvs-sample' \
--bucket="${YOUR_BUCKET_NAME}" \
--key='data.json' \
--delete

[ADDED] Following items will be added.
+---+-------+-------+
| # | KEY   | VALUE |
+---+-------+-------+
| 1 | key-4 | v 4   |
+---+-------+-------+

[UPDATED] Following items will be updated.
+---+-------+--------------+-------------+
| # | KEY   | BEFORE VALUE | AFTER VALUE |
+---+-------+--------------+-------------+
| 1 | key-1 | value-1      | v 1         |
+---+-------+--------------+-------------+

[DELETED] Following items will be deleted.
+---+-------+---------+
| # | KEY   | VALUE   |
+---+-------+---------+
| 1 | key-3 | value-3 |
+---+-------+---------+

If you add the --yes or -y flag, the synchronization will actually be executed.

$ cfkvs kvs sync \
--name='cf-kvs-sample' \
--bucket="${YOUR_BUCKET_NAME}" \
--key='data.json' \
--delete \
--yes

Sync items in the key value store with a JSON file

You can synchronize the key-value store with the JSON file specified by the --file flag in the same way as synchronizing with an S3 object.

If you specify the --file flag and --bucket and --key at the same time, the --file flag takes precedence.

$ cfkvs kvs sync \
--name='cf-kvs-sample' \
--file='./path/to/data.json'

Describe a key value store

The Describe action for CloudFront Key Value Store has two actions: CloudFront:DescribeKeyValueStore and CloudFrontKeyValueStore:DescribeKeyValueStore. The cfkvs kvs info command can get the merged information of these actions.

$ cfkvs kvs info --kvs-name='cf-kvs-sample' --output=json

Output:

{
    "id": "xxxxxxxx-0000-0000-0000-xxxxxxxxxxxx",
    "arn": "arn:aws:cloudfront::000000000000:key-value-store/xxxxxxxx-0000-0000-0000-xxxxxxxxxxxx",
