The sdaas-rdfstore requires docker

🚀 Quickstart

docker compose up -d --build
sleep 3
curl -X POST --data-binary "ASK {}" --header "Content-Type: application/sparql-query" http://localhost/sdaas/sparql
# should result  true
curl -X POST --data-binary "LOAD <http://lp/data/milan.ttl>" --header "Content-Type: application/sparql-update" http://localhost/sdaas/sparql
# should result in  mutationCount=28036

Test workbench:

• point browser to http://localhost/sdaas to see workbench interface
• in the UPDATE tab, tray executing: DROP ALL; LOAD <http://lp/data/lecco.ttl> INTO GRAPH <urn:graph:test>. You should read mutationCount=29241
• in the QUERY tab, tray executing: SELECT (COUNT(*) as ?n) {?s?p?o}. You should read 1205 for "n" variable
• free docker resource typing docker compose down

memory footprints and performances related to size:

size value	required RAM	edges (triples)
micro (default)	512M	<200K
small	2GB	<5M
medium	4GB	<10M
large	8GB	<50M
xlarge	16GB	<100M
xxlarge	32GB	<500M
custom	depends

The micro size is suitable for test and development environment.

The custom size let to you setting up proper configurations, see https://github.com/blazegraph/database/wiki/Hardware_Configuration

To persist data and improve performances, you should mount as a fast volume the directory /var/lib/rdfStore
