Event correlation is useful in many areas. For example, log processing, microservice coordination, IoT event processing. PHP-EC is being used in production for multiple IoT projects, some processing 10M+ events per day from multiple disparate systems. Requirements ------------ [](#requirements) The package is compatible with PHP 8.0+ Installation ------------ [](#installation) You can add the library as project dependency using [Composer](https://getcomposer.org/): ``` composer require edgetelemetrics/eventcorrelation ``` Performance can be improved by installing optional PHP extensions (ext-libuv or ext-libev) Examples -------- [](#examples) See [/examples](/examples) directory - [Online shopping service](/examples/online_shop/online_shop.php) Getting Started --------------- [](#getting-started) TBC. Components are: - Events: An event is made up of a type, date, id, and data - Event Stream: A time ordered stream of events - Input Processes: programs that provide event streams into PHP-EC. These can be PHP scripts, NodeJS, Bash script etc. - Actions: Programs that perform tasks when requested. This may be writing to a database, sending an email etc. - Rules: Rules define a set of events to be processed within a defined time period. Once a Rule is matched or a defined timeout period is exceeded the rule can: - run Actions (for example send email, write to database) - emit Events (emit a new or modified event for another Rule to handle \[chaining rules\]) - run an additional input process (load more data into the system) ### Cron Like Rules [](#cron-like-rules) PHP-EC supports rules that can call actions based on Cron time expressions, system start and system shutdown.
