==========
|
|
|
|
Features listed in this section should no longer be used, because they are
|
|
considered obsolete and may get removed in a future release. They are currently
|
|
kept for backward compatibility. There are usually better alternatives to
|
|
replace the old features with:
|
|
|
|
- **Simple Queries**: Idiomatic interface in arangosh to perform trivial queries.
|
|
They are superseded by [AQL queries](../aql/), which can also
|
|
be run in arangosh. AQL is a language on its own and way more powerful than
|
|
*Simple Queries* could ever be. In fact, the (still supported) *Simple Queries*
|
|
are translated internally to AQL, then the AQL query is optimized and run
|
|
against the database in recent versions, because of better performance and
|
|
reduced maintenance complexity.
|
|
|
|
- **Actions**: Snippets of JavaScript code on the server-side for minimal
|
|
custom endpoints. Since the Foxx revamp in 3.0, it became really easy to
|
|
write [Foxx Microservices](foxx.html), which allow you to define
|
|
custom endpoints even with complex business logic.
|
|
|
|
From v3.5.0 on, the system collections `_routing` and `_modules` are not
|
|
created anymore when the `_system` database is first created (blank new data
|
|
folder). They are not actively removed, they remain on upgrade or backup
|
|
restoration from previous versions.
|
|
|
|
You can still find the
|
|
[Actions documentation](https://www.arangodb.com/docs/3.4/appendix-deprecated-actions.html){:target="_blank"}
|
|
in 3.4 or older versions of the documentation.
