!CHAPTER Features and Improvements
The following list shows in detail which features have been added or improved in
ArangoDB 2.4. ArangoDB 2.4 also contains several bugfixes that are not listed
here. For a list of bugfixes, please consult the [CHANGELOG](https://github.com/triAGENS/ArangoDB/blob/devel/CHANGELOG).
!SECTION V8 version upgrade
The built-in version of V8 has been upgraded from 3.16.14 to 3.29.59.
!SECTION FoxxGenerator
ArangoDB 2.4 is shipped with FoxxGenerator, a framework for building
standardized Hypermedia APIs easily. The generated APIs can be consumed with
client tools that understand [Siren](https://github.com/kevinswiber/siren).
The FoxxGenerator can create APIs based on a semantic description of entities
and transitions. A blog series on the use cases and how to use the Foxx generator
is here:
* [part 1](https://www.arangodb.com/2014/11/26/building-hypermedia-api-json)
* [part 2](https://www.arangodb.com/2014/12/02/building-hypermedia-apis-design)
* [part 3](https://www.arangodb.com/2014/12/08/building-hypermedia-apis-foxxgenerator)
A cookbook recipe for getting started with FoxxGenerator is [here](https://docs.arangodb.com/cookbook/FoxxGeneratorFirstSteps.html).
!SECTION AQL improvements
!SUBSECTION Optimizer improvements
The AQL optimizer has been enhanced to use of indexes in queries in several
additional cases. Filters containing the `IN` operator can now make use of
indexes, and multiple OR- or AND-combined filter conditions can now also use
indexes if the filter conditions refer to the same indexed attribute.
Here are a few examples of queries that can now use indexes but couldn't before:
FOR doc IN collection
FILTER doc.indexedAttribute == 1 || doc.indexedAttribute > 99
RETURN doc
FOR doc IN collection
FILTER doc.indexedAttribute IN [ 3, 42 ] || doc.indexedAttribute > 99
RETURN doc
FOR doc IN collection
FILTER (doc.indexedAttribute > 2 && doc.indexedAttribute < 10) ||
(doc.indexedAttribute > 23 && doc.indexedAttribute < 42)
RETURN doc
Additionally, the optimizer rule `remove-filter-covered-by-index` has been
added. This rule removes FilterNodes and CalculationNodes from an execution
plan if the filter condition is already covered by a previous IndexRangeNode.
Removing the filter's CalculationNode and the FilterNode itself will speed
up query execution because the query requires less computation.
!SUBSECTION Language improvements
!SUBSUBSECTION `COUNT` clause
An optional `COUNT` clause was added to the `COLLECT` statement. The `COUNT`
clause allows for more efficient counting of values.
In previous versions of ArangoDB one had to write the following to count
documents:
RETURN LENGTH (
FOR doc IN collection
FILTER ...some condition...
RETURN doc
)
With the `COUNT` clause, the query can be modified to
FOR doc IN collection
FILTER ...some condition...
COLLECT WITH COUNT INTO length
RETURN length
The latter query will be much more efficient because it will not produce any
intermediate results with need to be shipped from a subquery into the `LENGTH`
function.
The `COUNT` clause can also be used to count the number of items in each group:
FOR doc IN collection
FILTER ...some condition...
COLLECT group = doc.group WITH COUNT INTO length
return { group: group, length: length }
!SUBSUBSECTION `COLLECT` modifications
In ArangoDB 2.4, `COLLECT` operations can be made more efficient if only a
small fragment of the group values is needed later. For these cases, `COLLECT`
provides an optional conversion expression for the `INTO` clause. This
expression controls the value that is inserted into the array of group values.
It can be used for projections.
The following query only copies the `dateRegistered` attribute of each document
into the groups, potentially saving a lot of memory and computation time
compared to copying `doc` completely:
FOR doc IN collection
FILTER ...some condition...
COLLECT group = doc.group INTO dates = doc.dateRegistered
return { group: group, maxDate: MAX(dates) }
!SUBSUBSECTION Subquery syntax
In previous versions of ArangoDB, subqueries required extra parentheses
around them, and this caused confusion when subqueries were used as function
parameters. For example, the following query did not work:
LET values = LENGTH(
FOR doc IN collection RETURN doc
)
but had to be written as follows:
LET values = LENGTH((
FOR doc IN collection RETURN doc
))
This was unintuitive and is fixed in version 2.4 so that both variants of
the query are accepted and produce the same result.
!SUBSECTION Web interface
The `Applications` tab for Foxx applications in the web interface has got
a complete redesign.
It will now only show applications that are currently running in ArangoDB.
For a selected application, a new detailed view has been created. This view
provides a better overview of the app, e.g.:
* author
* license
* version
* contributors
* download links
* API documentation
Installing a new Foxx application on the server is made easy using the new
`Add application` button. The `Add application` dialogue provides all the
features already available in the `foxx-manager` console application plus some more:
* install a Foxx application from Github
* install a Foxx application from a zip file
* install a Foxx application from ArangoDB's application store
* create a new Foxx application from scratch: this feature uses a generator to
create a Foxx application with pre-defined CRUD methods for a given list of collections.
The generated Foxx app can either be downloaded as a zip file or
be installed on the server. Starting with a new Foxx app has never been easier.
!SECTION Miscellaneous improvements
!SUBSECTION Default endpoint is 127.0.0.1
The default endpoint for the ArangoDB server has been changed from `0.0.0.0` to
`127.0.0.1`. This will make new ArangoDB installations unaccessible from clients other
than localhost unless the configuration is changed. This is a security precaution
measure that has been requested as a feature a lot of times.
!SUBSECTION System collections in replication
By default, system collections are now included in replication and all replication API
return values. This will lead to user accounts and credentials data being replicated
from master to slave servers. This may overwrite slave-specific database users.
If this is undesired, the `_users` collection can be excluded from replication
easily by setting the `includeSystem` attribute to `false` in the following commands:
* replication.sync({ includeSystem: false });
* replication.applier.properties({ includeSystem: false });
This will exclude all system collections (including `_aqlfunctions`, `_graphs` etc.)
from the initial synchronisation and the continuous replication.
If this is also undesired, it is also possible to specify a list of collections to
exclude from the initial synchronisation and the continuous replication using the
`restrictCollections` attribute, e.g.:
replication.applier.properties({
includeSystem: true,
restrictType: "exclude",
restrictCollections: [ "_users", "_graphs", "foo" ]
});
