Where to find or how to calc the shard_id to shard-number mapping ?

[lukas-becker0]

According to the documentation the shard_ids are calculated like this: shard_id = hash(recipient-id) % shard-number

We can findout which shard_id has been assigned to which phone number by checking the messages table in the messageStore database.

and I assume we can find the "shard-number" by looking at the id in the shard_map table in the clusterStore database.

There is however no table with the information which shard_id belongs to which shard. Also calculating which shard_id belongs to which shard is not possible without knowing what hashing algorithm was used.

Can you provide the hashing algorithm which is used to calculate the shard ids ?

Is there a database entry or log entry in one of the containers which provides the information which shard_ids belong to which shard ?
