-### Usage with PlanetScale Boost
-
-To enable PlanetScale Boost, run `SET @@boost_cached_queries = true` once. All subsequent queries run on the same connection will use boost if it's enabled for the query pattern. Non-matching queries will run as normal.

-```ts
-const conn = client.connection()
-// Enable boost for the connection
-await conn.execute('SET @@boost_cached_queries = true')
-
-const results = await conn.execute('...')

-// Optionally, you may disable boost for the connection by setting to false
-await conn.execute('SET @@boost_cached_queries = false')
