Prisma Subscriptions API

openapi: 3.1.0
info:
  title: Prisma Accelerate Aggregation Subscriptions API
  description: API for Prisma Accelerate, a fully managed global connection pool and caching layer for existing databases. Accelerate intercepts Prisma Client queries via a proxy protocol, applies query-level cache policies with configurable TTL and stale-while-revalidate strategies, and provides tag-based cache invalidation. The proxy uses the prisma:// connection protocol to route queries through Accelerate's global edge network.

      summary: Prisma Create a transient event subscription
