The reftable format is structured as a sequence of blocks, and each block contains a sequence of prefix-compressed key-value records. There are 4 types of records, and they have similarities in how they must be handled. This is achieved by introducing a polymorphic 'record' type that encapsulates ref, log, index and object records.
