The investigation has cost me several days and I hope that by writing this up I can entertain others and save them the journey. TL;DR If…

We used the arangobench benchmark and test tool for these tests. The tests include 10 different test cases with changing test parameters like concurrency, batch…

Now you want to get some figures how many end users your system will be able to serve. Therefore you define “scenarios” which will be typical for what your users do. One such a…

The tests will compare the AQL query execution times in 2.5 and 2.6. The results look quite promising: 2.6 outperformed 2.5 for all tested queries, mostly by factors of 2 to 5. A few dedicated AQL features in the tests got…

While the HTTP API can easily be tested with any HTTP client and any JavaScript code that can be isolated from the ArangoDB APIs could be tested in similar environments like Node.js or io.js, it was all but impossible to…

Because of that access to common data structures to these threads have to be protected from concurrent access. ArangoDB currently uses mutexes, spinlocks and RW-locks for that. With the ongoing development of the MVCC the number of situations where protected access is needed grows…

Sometimes people want to secure this connection and use SSL or TLS instead. That is where we are using OpenSSL. It provides all the methods to implemented HTTPS on top of an HTTP server. It worked well and the corresponding code is only some 300…

With the release of ArangoDB 1.4.0 I now tried to compile it again. As all patches required for 1.3 are part of 1.4.0 it is now much easier. pi> sudo apt-get install libreadline6 libreadline6-dev libssl-dev pi> git clone -b v1.4.0 https://github.com/triAGENS/ArangoDB…
