Sequence Generator Meaning FAQ
Additional questions about the meaning and context of 'sequence generator' across different fields.
How do I explain the difference to a non-technical person?
Think of it like a counter with rules. In math, it is a list of numbers following a pattern. In ETL, it is a tool that assigns unique IDs to database rows. In electronics, it is a circuit that cycles through states on a timer.
Are sequence generators in ETL and Snowflake the same concept?
They serve the same purpose (generating unique numeric identifiers) but operate at different layers. ETL generators run inside the data pipeline tool. Snowflake sequences run inside the database. Best practice: pick one layer as the single source of truth for keys.
What is a state machine sequence generator?
In digital electronics, a sequence generator is a finite state machine that cycles through predetermined states. Each clock pulse advances to the next state. Common examples include counters (0,1,2,3...) and pseudo-random pattern generators used in testing.
