In a worst case scenario it was up to 2% slower, however run-to-run variations of pgbench were The recent benchmark published under the title “PostgreSQL UUID Performance: Benchmarking Random (v4) and Time-based (v7) UUIDs” gives numbers that support the Much has been written about the issues with using UUIDs as primary keys in Postgres and other RDBMS. But we can use application I’ve demonstrated the size benefits of bigint but my uuidv7 performance is so good it basically matched bigint – but I’m guessing this Postgres UUID v7 for versions before Postgres18 (which includes uuidv7) - uuid_v7_optimized. This suite tests insert and select performance across three In this article, we'll benchmark UUIDv4 and UUIDv7 in PostgreSQL by comparing their insert speeds, index sizes, and query Comprehensive analysis of modern time-ordered identifiers in PostgreSQL: UUIDv7, ULID, and TypeID implementations with real performance benchmarks, PostgreSQL 18 native support, On average, pg_uuidv7 is as fast as the native gen_random_uuid() function in Postgres. Read more here: https://datatracker. It explores indexing, write amplification, and query performance—offering best Most of the Postgres tests and discussions on UUID-v7 I’ve seen these last months (see the References below) used a patched Postgres and assumed that this will be supported sqlalchemy uuid for sqlite. GitHub Gist: instantly share code, notes, and snippets. If you check out the links I shared above you'll see that insertion performance with Postgres UUIDv6 (non-standard) .
