Foxx Dependencies: Composing More Flexible Foxx Apps
Previously on the ArangoDB blog we saw how we can use the configuration field in manifest.json to make Foxx apps configurable and more re-usable. This is all well and good if we just want to pass in simple values to a Foxx app but sometimes you want to pass in entire Foxx apps. This is…

Reusable Foxx Apps with Configurations: ArangoDB Development
While the optional configuration field in Foxx manifests had experimental support all the way back to ArangoDB 2.1, the feature was previously undocumented and not well understood. The upcoming ArangoDB 2.6 release officially introduces Foxx configurations, allowing you to make your existing Foxx apps more re-usable and to make better use of third-party apps. Let’s…
IN List Improvements: ArangoDB Query Enhancement
Another performance improvement could be accomplished in the latest devel-branch: The handling of large IN-lists. Those become much faster than in the previous releases. Large IN-lists are normally used when comparing attribute or index values against some big array of lookup values or keys provided by the application. Read on how this improvement reduces query…
Bulk Document Lookups: Efficient Data Retrieval with ArangoDB
ArangoDB 2.6 comes with a specialized API for bulk document lookups. The new API allows fetching multiple documents from the server using a single request, making bulk document retrieval more efficient than when using one request per document to fetch. Provided the documents keys are known, all the client application needs to do is to…
Full-Text Index Enhancements: ArangoDB Search Optimization
This post is about improvements for the fulltext index in ArangoDB 2.6. The improvements address the problem that non-string attributes were ignored when fulltext-indexing. Effectively this prevented string values inside arrays or objects from being indexed. Though this behavior was documented, it was limited the usefulness of the fulltext index much. Several users requested the…
String Comparison Performance: ArangoDB Query Optimization
We’ve been using Callgrind with its powerful frontend KCachegrind for quiet some time to analyse where the hot spots can be found inside of ArangoDB. One thing always accounting for a huge chunk of the resource usage was string comparison. Yes, string comparison isn’t as cheap as one may think, but its been even a…
