Postgres push triggers

Watch a table for changes and push a notification with a payload describing the change.

Example

In the Postgres shell:

-- Create the functions

SQLite Update Hook Example

This is an example usage of registering an update_hook to a SQLite connection. The motivation for exploring this feature is to test out various implementations of data monitoring interfaces.

A few notable properties of the implementation:

  • The hook must be registered on the connection being used which requires clients to manually integrate this code.
  • Each INSERT and UPDATE operation requires a subsequent SELECT to get the row data.
  • When registering the hook, increasing the bufsize under heavy workloads will improve throughput, but the SQLite library is single-threaded by design.
