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.
