Auto-Generate GraphQL for ArangoDB
Currently, querying ArangoDB with GraphQL requires building a GraphQL.js schema. This is tedious and the resulting JavaScript schema file can be long and bulky. Here we will demonstrate a short proof of concept that reduces the user related part to only defining the GraphQL IDL file and simple AQL queries. The Apollo GraphQL project built…
ArangoDB | PyArango Performance Analysis – Transaction Inspection
Following the previous blog post on performance analysis with pyArango, where we had a look at graphing using statsd for simple queries, we will now dig deeper into inspecting transactions. At first, we split the initialization code and the test code. Initialisation code We load the collection with simple documents. We create an index on…
Performance analysis using pyArango Part I
This is Part I of Performance analysis using pyArango blog series. Please refer here for: Part II (cluster) and Part III (measuring system capacity). Usually, your application will persist of a set of queries on ArangoDB for one scenario (i.e. displaying your user’s account information etc.) When you want to make your application scale, you’d…
ArangoDB | Geo Demonstration Using Foxx – Location-Aware Applications

As HTML5 progressed and due to a long history of critical security vulnerabilities this is – technologically speaking – certainly the right decision. However I tended to also become a bit sad. Flash was the first technology that brought interactivity to…
