Description of Changes

If/when we have ABI breaking changes, this directory can cause benchmarks to start failing.

API and ABI breaking changes

None

Expected complexity level and risk

Testing

Describe any testing you've done, and any testing you'd like your reviewers to do,
so that you're confident that all the changes work as expected!

• Write a test you've completed here.
• Write a test you want a reviewer to do here, so they can check it off when they're satisfied.

Callgrind benchmark results

Callgrind Benchmark Report

These benchmarks were run using callgrind,
an instruction-level profiler. They allow comparisons between sqlite (sqlite), SpacetimeDB running through a module (stdb_module), and the underlying SpacetimeDB data storage engine (stdb_raw). Callgrind emulates a CPU to collect the below estimates.

Measurement changes larger than five percent are in bold.
