An abstract php connector for elasticsearch 7.
composer require eos/elasticsearch-7-connector
How to use?
This library provides abstract classes with base functionalities.
Your domain classes (e.g. repositories, event handlers or command processors) should extend the AbstractConnector
or, if you want to use parallel indices, the AbstractParallelIndexConnector.
Method provided by abstract classes
All methods are defined as protected and designed for internal usage in your extending class.

AbstractParallelIndexConnector:
Dependencies
The AbstractConnector requires an instance of ConnectionFactoryInterface and an instance of IndexDefinerInterface
(AbstractParallelIndexConnector instead requires ParellelIndexDefinerInterface).
Optional you can provide a bulkSize. If the bulkSize, which is 0 by default, is greater then 1, bulk requests with
the given bulk size will be executed instead of single requests for each storage operation.
ConnectionFactoryInterface
The connection factory is responsible for creating instances of Elasticsearch\Client.
The provided implementation of ConnectionFactoryInterface is SimpleConnectionFactory, which will take a single (!)
dsn (scheme://host:port) as constructor argument.
IndexDefinerInterface
Index definers provide methods, which contains/creates the elasticsearch definition of a specific index.
An index definer can provide more then one index definition but only one for each type.
Each type will be stored in its own index.
If you want to use one index definer for each type, your index definers could extend AbstractIndexDefiner and can be added
to an instance of IndexDefinerRegistry.
If you want to prefix all your index names with the same base name, you could wrap the IndexDefinerRegistry into an instance of PrefixedIndexDefiner
(its also possible to wrap each single index definer into its own PrefixedIndexDefiner or define full index names directly in your index definer).
Docker / Docker Compose
For local development a docker container with all required components (php, composer) can be created and used:
Build and start the container
docker-compose up --build -d
Execute a command in the container (here "composer install"):
docker-compose exec app sh -c "composer install"
