# parallel-leader-participation-test

Test effects of Postgres parallel_leader_participation settings

# Prerequisites

* AWS CLI installed / configured

* [pg-spot-operator](https://github.com/pg-spot-ops/pg-spot-operator) Python CLI installed

* Ansible installed

# Running the test

```

./launch_vms_and_run_test.sh run1-local eu-south-2 local 100

```

# Analyzing the results

Load the pg_stat_statements dump files from `results` folder into a local Postgres instance:

```

for x in `ls -1 results/*.dump` ; do psql -f $x ; done

```

A `pgss_results` table will be created. See the queries from `analyze_results.sql` as a base line.
