AGEFreighterを使った簡単なグラフデータのデモ

Apache AGEのハンズオンをやらんとならんので、ざっと書いた。
# deploy Azure Database for PostgreSQL
# add AGE extension to 'azure.extensions' and 'shared_preload_libraries' in 'parameters' section in 'Settings' blade on Azure Portal

# or, run docker container
docker pull apache/age
docker run \
    --name age  \
    -p 5455:5432 \
    -e POSTGRES_USER=postgres \
    -e POSTGRES_PASSWORD=postgresPW \
    -e POSTGRES_DB=postgres \
    -d \
