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 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 overwhelm the 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 prov photo editing servies iders 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. Furthermore although it can be used with many The database engine works with providers but 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 .
