Remember that a discord message may be transformed to multiple matrix messages.
|
||
|
|
|
||
|
|
A database will be used to store the discord id to matrix event id mapping. Table columns:
|
||
|
|
- discord id
|
||
|
|
- matrix id
|
||
|
|
- the "type" of the matrix id, used to update things properly next time. for example, whether it is the message text or an attachment
|
||
|
|
|
||
|
|
There needs to be a way to easily manually trigger something later. For example, it should be easy to manually retry sending a message, or check all members for changes, etc.

|
