Twitter Update Sink

Updates the authenticating user’s current text (e.g Tweeting).

Note	For each update attempt, the update text is compared with the authenticating user’s recent Tweets. Any attempt that would result in duplication will be blocked, resulting in a 403 error. A user cannot submit the same text twice in a row.

While not rate limited by the API, a user is limited in the number of Tweets they can create at a time. The update limit for standard API is 300 in 3 hours windows. If the number of updates posted by the user reaches the current allowed limit this method will return an HTTP 403 error.

You can find details for the Update API here: https://developer.twitter.com/en/docs/tweets/post-and-engage/api-reference/post-statuses-update

Configuration

TwitterUpdateConsumerConfiguration exposes 2 composable functions:

• Function<Message<?>, StatusUpdate> messageToStatusUpdateFunction(TwitterUpdateConsumerProperties updateProperties) - Converts input message into StatusUpdate query object.

• Consumer<StatusUpdate> updateStatus(Twitter twitter) - Sends the input StatusUpdate argument as Twitter text update.

Use @Import(TwitterUpdateConsumerConfiguration.class) to compose those functions.

By default the twitter-update implements the following composite function chain: spring.cloud.function.definition=byteArrayTextToString|messageToStatusUpdateFunction|updateStatus or (byteArrayTextToString|twitterStatusUpdateConsumer)
