streaming-subscriptions-bench

This is a very simple way to validate the runtime characterstics of streaming subscriptions on the database.

Benchmarking methodology

1. There are 2 parts to benchmarking: 1) a streaming subscriber, 2) concurrent mutations
2. We consider different database models: model_simple.ddl and model_partition.ddl
3. We start a streaming subscription and start concurrent mutations (configurable concurrency, default: 1000)
4. We check pg_stat_statements to check the max_time of execution of the SQL query. We also monitor the benchmarking app and the database for load (cpu/mem)

Todo

1. We should test with concurrent subscribers as well.
