Struct BatchExecutorBuilder

pub struct BatchExecutorBuilder<E>
where
    E: Executor + Send + Sync + 'static,
{ /* private fields */ }

Used to configure a new BatchExecutor. A BatchExecutorBuilder is returned from BatchExecutor::build.

Implementations

impl<E> BatchExecutorBuilder<E>

where E: Executor + Send + Sync + 'static,

pub fn delay_duration(self, delay: Duration) -> Self

The maximum amount of time the BatchExecutor will wait to queue up more keys before calling the Executor.

pub fn eager_batch_size(self, eager_batch_size: Option<usize>) -> Self

The maximum number of keys to wait for before eagerly calling the Executor. A value of Some(n) will load the batch once n or more keys have been queued (or once the timeout set by delay_duration is reached, whichever comes first). A value of None will never eagerly dispatch the queue, and the BatchExecutor will always wait for the timeout set by delay_duration.

Note that eager_batch_size does not set an upper limit on the batch! For example, if BatchExecutor::execute_many is called with more than eager_batch_size items, then the batch will be sent immediately with all of the provided values.

pub fn label(self, label: impl Into<Cow<'static, str>>) -> Self

Set a label for the BatchExecutor. This is only used to improve diagnostic messages, such as log messages.

pub fn finish(self) -> BatchExecutor<E>

Create and return a BatchExecutor with the given options.
