Intent
This PR add a specific implementation of
digest_to_checksumfor SQL server which speeds up the computation of checksums on the backend.(Most of these updates are taken from @marcusmunch's fork)
Approach
A S3 method is added for SQL Server connections which uses the built-in
HashBytesto compute checksums with SHA_256 instead of copying the data to the local session and using the Ropenssl::md5algorithm.Known issues
