Use null instead of -1 value.

Use default Random constructor if no seed is passed by CLI argument.

Remove useless comment.

As told on IRC, I was waiting on adding all benchmarking interfaces before implementing the CLI options.

• Add a new meta info nbEdgesAccessed
• Move utils/ into benchmark/utils/

I don't think you should put yourself in the contributors of a template repo

Remove CONTRIBUTORS changes.

Results from Azure with random write using custom mmap:

Update JSON output format in api.rst (content -> result, add meta dict).

Update documentation (api.rst and server README).

• Timings are now optional
• Improve JSON output structure (rename Result class to Output, rename

content member to result, add meta member)

I hadn't in mind to lift the timings up to the REST layer, but why not, it will enable doing interesting stuff using non Java clients.

Add method to pick random nodes with specific type

Use LazyLongIterator instead of array in NeighborsIterator

Add reference to T1885 in commit message.

I rebooted the azure VM and did the benchmark, here is the result for 1M edges:

Rebasing on master.

Add clean-javadoc target.

Last solution I tried: using a custom mmap output file instead of the temporary array. On monster, results seem better!

• Refactor into a step_info function
• Use "* swh-graph:" prefix
• Add step numbering

Due to multiple server maintenance, the process was re-started a few times, but it is now finished and results are uploaded in the annex: https://annex.softwareheritage.org/public/dataset/graph/latest/compressed/all+ori/

Some updates on the running experiments, I tried with both monster and our new azure VM.

What was tried so far:

Add CONTRIBUTORS file
