I'd like to switch my database from Snappy to Zstd compression.
 
Currently, it doesn't seem that it is possible to change the compression of an existing collection.
 
It would be nice if there were a way to do this, even if (for example) it required making a new replica set member which "re-compresses" the data to the new algorithm while cloning it.
 
My account rep is recommending today that I create a new collection and manually copy with mongodump/mongorestore which doesn't seem to be a viable option, for data consistency reasons.
