Why PostgreSQL lasted

  • It is the database you graduate to, and then never leave.
  • Extensions (PostGIS, pgvector, Citus) let it absorb the specialty database of the year without a migration.

Why Redis lasted

  • If you need a cache, a queue, or a counter, you reach for it without a meeting.
  • The data structures are the product. Everything else is a license argument.
