Guid vs int join performance. Segment's also developed their own algorithm KSUID. an approach that uses a BIGINT as PK and has the UUID as a separate field. Tables contain BOTH an auto-increment primary key integer id column AND a guid column. There is w Nov 29, 2013 · I'm aware of the implications of using a GUID as a clustered primary key, hence the integer clustered index but does using a GUID as a primary key and therefore foreign keys on other tables have significant performance implications? We would like to show you a description here but the site won’t allow us. Aug 20, 2021 · Here is for instance a performance analysis (for MySQL though) comparing using the "official" UUIDs in the wrong way as PK vs. Jan 14, 2026 · In the world of database design, choosing the right primary key is critical for performance, scalability, and data integrity. But on the other hand Stripe is using IDs like ch_3L9o8x2eZvKYlo2C0UFoBfSp, in_1L9o8y2eZvKYlo2CMcdIG9aZ. Usage of keys in Power BI Int or Bigint sequential IDs are fast, faster than UUID or text, is what I learned. using a custom UUID that has nice sequential properties vs. g. nfsu zmducc chkk uwrv gtl gfof ciz ywmro zhtu htk
