ArangoDB 2.8.2 maintenance release comes with several replication improvements and bug fixes. You can download the latest version from our download page.

What’s changed:

• the continuous replication applier will now prevent the master’s WAL logfiles from being removed if they are still needed by the applier on the slave. This should help slaves that suffered from masters garbage collection WAL logfiles which would have been needed by the slave later.

  The initial synchronization will block removal of still needed WAL logfiles on the master for 10 minutes initially, and will extend this period..

Explain Improvements

Explaining AQL queries becomes even easier in ArangoDB 2.8. While previous versions required writing a hard-to-memorize command like

require("org/arangodb/aql/explainer").explain(query);

to explain an AQL query from the ArangoShell, 2.8 reduces this task to a mere

db._explain(query);

Apart from that, explain in 2.8 is smarter when confronted with very lengthy query strings, and with queries that contain huge hard-coded string, array, or object values.

We welcome 2016 with our first big news yet – the release of ArangoDB 2.8!

Now you can use new AQL keywords to traverse a graph even more convenient – a big deal for those who like to get the maximum out of their connected data. ArangoDB is getting faster with every iteration, in this release we have implemented several AQL functions and arithmetic operations in super-fast C++ code, optimizer rules and indexing improved further to help you getting things done faster.

AQL keywords added

The following AQL keywords were added in ArangoDB 2.8:

While working on the upcoming ArangoDB 2.8, we have reimplemented some AQL functions in C++ for improved performance. AQL queries using these functions may benefit from using the new implementation of the function.

The following list shows the AQL functions for which a C++ implementation has been added in 2.8. The other C++-based AQL function implementations added since ArangoDB 2.5 are also still available. Here’s the list of functions added in 2.8:

• document-related functions: DOCUMENT, EDGES, PARSE_IDENTIFIER
• numerical functions: ABS, FLOOR, RAND, ROUND, SQRT
• statistical functions:..
