These drivers use different protocols

zombies and maintain an internal connection pool so the database doesn’t get flooded. In addition to this an increasing number of cloud providers do not allow arbitrary connections which makes it challenging to work with existing databases that rely on connections. Using a traditional database with serverless capabilities can quickly lead to The database is overwhelmed. Serverless functions drain database connections quickly Serverless functions were developed in response to the above issues to provide a better experience for applications running on serverless functions. In addition, some database providers have also developed their own database driver libraries.  such as or instead of traditional connections and are therefore ideal for the rapidly evolving serverless world. So how do these serverless drivers fit in? A key part of the serverless drivers that have been supported now since their initial release is the query engine.

The query engine is written to allow client queries to be reliably and efficiently converted into statements and then executed through the accompanying database driver. The syste photo editing servies m used to work fine but a few months ago we noticed a trend of new database providers offering serverless database drivers written in . These drivers communicated with special endpoints. Our team knew that building a Java-based implementation that communicated with these new endpoints would be a daunting task. Diagram showing the client using the query engine to open a long-lived connection to the database. The client can communicate with the database without a driver adapter. Additionally, while it works with many database engines and providers, it can only connect to these databases through .



Direct connections or through connection pooling, for example. Both problems are now solved with the introduction of driver adapters that enable the use of existing database drivers when connecting to supported databases. Today we are releasing two driver adapters and. These adapters act as translators between clients and serverless database drivers. If you use a database driver and driver adapter your application no longer requires a direct connection to the database to run but instead communicates with the database through an or connection. Use an engine to translate client queries and then run those queries through these drivers. With this setup we are able to provide the best of both worlds: a battle-tested query engine and the ability to use a growing number of providers within the supported code base. The diagram shows the client using a query engine to translate the query but using a separate database driver for communication. Clients use driver adapters and serverless database drivers to .
