Instances
pattern ColFingerprint :: (Eq a, IsString a) => a #
Fingerprint of all columns in source table. Implemented as base-64 encoded sha256 of contents separated by '1'
pattern ColFingerprintSerial :: (Eq a, IsString a) => a #
Used to differentiate duplicates
pattern ColValidFrom :: (Eq a, IsString a) => a #
Timestamp of first tardis run the row appeared in
pattern ColValidTo :: (Eq a, IsString a) => a #
Null when the row was still there last time tardis ran, otherwise a timestamp of tardis run that detected row missing
pattern ColIsLatest :: (Eq a, IsString a) => a #
Indicates the last revision of a record (if primary key is in use). If ColValidTo is not null then the row has been deleted already.
