+Customers on a Workers Paid plan can configure up to 1,500 origin database connections per Hyperdrive configuration. This increases the connection pool size available for workloads that need more concurrent database access.
+
+The origin connection limit is the maximum number of database connections that Hyperdrive can make to your origin database. You can configure this value in the dashboard settings for your Hyperdrive configuration.
+
+Set this value lower than your origin database's own connection limit to leave room for adjustments.

 For instance, if your Worker makes many queries to your database (which cannot be resolved by Hyperdrive's caching), you may want to allow Hyperdrive to make more connections to your database.
 Conversely, if your Worker makes few queries that actually need to reach your database or if your database allows a small number of database connections, you can reduce the amount of connections Hyperdrive will make to your database.

 ## How Hyperdrive pools database connections
 
 Hyperdrive will automatically scale the amount of database connections held open by Hyperdrive depending on your traffic and the amount of load that is put on your database.
 
-The `max_size` parameter acts as a soft limit - Hyperdrive may temporarily create additional connections during network issues or high traffic periods to ensure high availability and resiliency.
+The origin connection limit is the maximum number of database connections that Hyperdrive can make to your origin database. This is a soft limit, so set it lower than your origin database connection limit.
+
+Hyperdrive may create more connections if network disruptions prevent existing connections from being used.

This means that it is possible for Hyperdrive to make more connections to your database than this limit in the event of network failure to ensure high availability.
