This PR introduces a `Context` object that is stored in the `Completion`
that currently only stores a `Waker`. In the future, I want to add some
sort of abort signal so that we can abort tasks that share the same
Context. To pass the Waker, I introduced a `step_with_waker` function in
`Statement` that delegates to an internal `_step` function. `_step` is
the previous `step` but just with the `Option<&Waker>` argument.
I was going to try and have the BusyHandler by truly async as well, but
I decided to not do it here, because it will be slightly complicated to
achieve.
Closes#3535
Replace #[tokio::main] with explicit Runtime builder to set the number
of tokio worker threads to match the benchmark thread count. This
ensures proper thread control and avoids interference from default
tokio thread pool sizing.
Remove verbose output from rusqlite benchmark and output only CSV
format: system,threads,batch_size,compute,throughput
This makes it easier to parse and plot benchmark results.
Replace the sleep-based --think parameter with a --compute parameter
that uses a busy loop to simulate realistic CPU or GPU bound business
logic (e.g., parsing, data aggregation, or ML inference). The compute
time is now specified in microseconds instead of milliseconds for
finer granularity.
…e connection
With BEGIN CONCURRENT, we cannot use the same connection all the time
because there's no way for the transaction manager to know which
transaction belongs to what "session" -- they're all individual
statements executed in the context of the one connection.
