Extending / Storage Layer / Overview of Bolt Storage
Note: You are currently reading the documentation for Bolt 3.7. Looking for the documentation for Bolt 5.2 instead?
The internals of the Bolt storage system have been significantly refactored for the 3.x series of releases. This section gives an overview of the responsibilities of each component. Note that this section will only be of interest to you if you need to interact with the storage internals, either when writing application code or perhaps in developing an extension.
If you are just interested in fetching content records then you can continue to refer to the content fetching pages.
Hierarchy of Storage in BoltΒΆ
There is a single point of entry for all storage interactions within Bolt and
this is usually accessible with a call to $app['storage']
. If you implement
your own controllers, which is normally recommended when you want control over
content fetching, then any queries that you would like to make can be accessed
through this object.
The basic hierarchy of the storage layer is described below, and clicking through gives a much more indepth description of the functionality of each layer.
Whilst there are individual responsibilities for each of these layers, in
practice you can perform most normal search, insert, update and delete
operations by interacting only with the EntityManager
which within Bolt is
accessed with a call to $app['storage']
.
