Tapbacks

Tapbacks look like normal messages in the database. Only the latest tapback state is stored. For example:

• user receives message -> user likes message
  • This creates a message and a like message.
• user receives message -> user likes message -> user unlikes message
  • This creates a message and a like message.
  • The like message is removed when the unlike message arrives.
  • Removed rows leave gaps in ROWID; the row ID is not reused.
  • The database keeps the latest tapback state, not the full tapback history.

Technical detail

The index specified by the prefix identifies a parsed message body part; see Message::components.

• bp: GUID prefix for bubble message tapbacks (url previews, apps, etc).
• p:0/ GUID prefix for normal messages (body text, attachments).

If a message has 3 attachments followed by some text:

• 0 is the first image
• 1 is the second image
• 2 is the third image
• 3 is the text of the message

In this example, a Like on p:2/ is a like on the third image.
