Serverless database drivers. This feature allows users to leverage existing database drivers to communicate with the database without the need for long-lived connections What is a Serverless Database Driver Traditionally database drivers establish long-lived connections with the database to communicate. Although the connection has some overhead initially there is almost no overhead for ongoing communication making it ideal for server deployments. But long-lived connections can cause problems in a serverless environment. Given the ephemeral nature of serverless functionality, it can become a tedious job to keep track of connections, close idle connections, handle zombies and maintain an internal connection pool so that the database does not get overwhelmed. 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. serverless capabilities can quickly overwhelm the database.

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 fun photo editing servies ctions. In addition, some database providers have also developed their own database driver libraries. These drivers use different protocols 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 system 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  .
