I'm curious, does a transaction in the FileStorage contain all the oid's to be effected by that transaction? Is it split-up (appended) by transaction or oid? Transaction, I believe.
FileStorage contains transaction records, which themselves contain data records. The data records contain the oid's. The basic procedure for a write goes something like this: tpc_begin() : start the transaction by setting up the tempfile where data records are written before the final commit store() : called for each object to be stored, writes the data record for the object to the temp file tpc_finish() : commits the transaction by writing the transaction record header, the data records from the temp file, then the transaction record footer Then load() just retrieves the latest data record for the object, it doesn't need to know about transactions.
