As part of an ETL process, I need to generate an SHA1 fingerprint that uniquely defines a row of data (collisions will have to be handled as well) for the audit trail. The data in tables consists of short strings and floating point values.
What's the best way to get an SHA1 fingerprint of a row that will work across databases and also work in non-Python programming languages (Python is used in the ETL process, but the main apps use C++ and SQL)? I'm concerned that the floating point numbers are going to make the SHA1 process unstable. Also, as a general question, does anybody know of some useful ETL frameworks that use SQLAlchemy?
