The subject technology identifies a set of functions included in a set of files corresponding to a library. The subject technology, for each function in the set of functions, registers the function as a user defined function (UDF). The subject technology generates a name for the function based at least in part on a predetermined prefix, wherein the predetermined prefix comprises an alphanumeric string. The subject technology generates, using at least a particular set of input parameters utilized by the function and a particular type of parameter of each input parameter of the particular set of input parameters, a particular set of source code. The subject technology stores information corresponding to the function in a metadata database. The subject technology provides access to the function in a different application.

Multiple user defined functions registration

The subject technology identifies a set of functions in a set of files corresponding to a library. The subject technology, for each function, registers the function as a user defined function (UDF) based on a set of input parameters utilized by the function and a type of parameter of each of the input parameters. The subject technology provides access to each registered function in a different application.

Registration of multiple user defined functions

The subject technology receives a set of files corresponding to a library, the library comprising a set of functions included in the set of files. The subject technology parses the set of files. The subject technology identifies a set of functions in the set of files based on the parsing. The subject technology, for each function, registers the function as a user defined function (UDF) based on a set of input parameters utilized by the function and a type of parameter of each of the input parameters. The subject technology provides access to each registered function in a different application.

The subject technology generates a unique identification that references a first connection object of a first deployment and a second connection object of a second deployment of a database. The subject technology receives a notification that the first deployment is unavailable, the notification that the first deployment is unavailable comprises an indication of a downtime for the first deployment. The subject technology provides an external connection group unique identification to the second deployment for the second deployment to determine whether a client is to be connected to the second deployment. The subject technology receives a uniform resource locator from the second deployment when a client device is to be connected to the second deployment, the uniform resource locator being provided to the client device for connecting to the second deployment.

Connection management in a distributed database

Systems, methods, and devices for transitioning a client connection for a database from a first deployment of the database to a second deployment of the database. A method includes maintaining the client connection between a client and the first deployment such that database traffic occurs at the first deployment. The method includes generating a unique identification that references a first connection object of the first deployment and a second connection object of a second deployment. The method includes receiving a notification that the first deployment is unavailable and providing an external connection group unique identification to the second deployment for the second deployment to determine whether the client should be connected to the second deployment. The method includes receiving a uniform resource locator from the second deployment if the client should be connected to the second deployment.
