The index for message was fairly inefficient as it was only using the
cursor, as it was referring to the old `chat_id` field.
This meant that newer messages would be fetched much faster then older
messages.
The index has been changed so that now it includes `local_chat_id`
(which is currently used for filtering), and not using `hide`.
The reason being is that `hide` is a low cardinality index, so there's
no performance benefit to have it in, also it's mostly ignored by the
query planner.
This commit also adds the missing migrations, we generated the file, but
the source was missing, probably I forgot to add them in a rebase. They
have been generated from the migration file, using `RestoreAsset`.
'm trying to add more documentation to parts of the repo that I go into.
I feel this basic history will make it easier to understand why the protocol package is as big as it is compared to the other packages in the repo, and help in understanding its existence.
We used *Raw method in message_processor as before we had non-Raw method
during the transition from status-react to status-go. This naming is not
meaningful anymore, so I have changed it.
Images are too large to be sent over waku/whisper with the
current PoW (0.002).
This commit lowers the PoW for sending messages to a lower value,
depending on the size.
This means that older clients will not be able to receive messages that
are greater than 50KB (none of the messages we currently send is anywhere close to
that, most of them are less than 1KB).
I would have preferred to set the PoW explicitly for images to be lower,
but it's not trivial as we use `datasync` to send messages and its
interface takes a payload that is to be dispatched and a function to
dispatch, at initialization stage.
This make it difficult (impossible?) to set a different PoW for a
particular message, without changing function signature in datasync
(which is agnostic to the transport used).
So a less cumbersome approach is to just fingerprint on size.
