Data for --source 'generate'

When --source 'generate' is specified, --count is required to specify the number of users to generate. For each generated user, a pod is generated and filled with dummy files containing random data, with various sizes ranges from 10 byte to 10MB.

Data for --source 'dir'

For --source 'dir', the --dir option requires a "dir with the generated data". This dir is generated with ldbc-snb-decentralized:

git clone https://github.com/rubensworks/ldbc-snb-decentralized.js.git
cd ldbc-snb-decentralized.js
npm install
docker pull rubensworks/ldbc_snb_datagen:latest
bin/ldbc-snb-decentralized generate --scale 0.1 --overwrite --fragmentConfig config-posts-to-person.json

(config-posts-to-person.json can be found in this repo)
