Implementations

impl ConnectorVersion

pub fn max_bind_values(&self) -> Option<usize>

The maximum number of rows allowed in a single insert query.

max_bind_values is overriden by the QUERY_BATCH_SIZE env var in targets other than WASM.

Connectors which underyling implementation is WASM don’t have any max_bind_values override as there’s no such thing as runtime environment.

From the PoV of the test binary, the target architecture is that of where the test runs, generally x86_64, or aarch64, etc.

As a consequence there is an mismatch between the the max_bind_values as seen by the test binary (overriden by the QUERY_BATCH_SIZE env var) and the max_bind_values as seen by the WASM engine being exercised in those tests, through the RunnerExecutor::External test runner.

What we do in here, is returning the number of max_bind_values hat the connector under test will use. i.e. if it’s a WASM connector, the default, not overridable one. Otherwise the one as seen by the test binary (which will be the same as the engine exercised)
