Create Environment Script

Create the file setenv.sh in the following way. You're free to choose whatever values you like. Note the following.

• SAMPLES is the number of (title, embedding) pairs to import into the database.
• TRANSACTIONS is the actual number of benchmark operations to perform, referring to the number of queries to make.
• APIKEY is the API Key for AnnDB, which also is being evaluated here.
• DATASET is the name of a dataset in AnnDB. See the documentation there for more information.

export PGHOST=localhost
export PGPORT=6432
export PGDATABASE=pgbench
export PGUSER=pgbench
export PGPASSWORD=pgbench
export SAMPLES=10000000
export TRANSACTIONS=10
export APIKEY=<redacted>
export DATASET='wikipedia-titles'

Start PostgreSQL Database

In one terminal window, run the following command to run an instance of PostgreSQL in a Docker image, using the environment variables established in setenv.sh.

source setenv.sh && docker run -e POSTGRES_DB=$PGDATABASE -e POSTGRES_USER=$PGUSER -e POSTGRES_PASSWORD=$PGPASSWORD -p $PGPORT:5432 postgres:13.2

Run Benchmark

In another terminal window, run the following command to run the benchmark, using the same environment variables established in setenv.sh.

source setenv.sh && time make clean report.txt
