pub struct SubscriptionConsumer;Expand description
Static methods for consuming subscription data.
Implementations§
Source§impl SubscriptionConsumer
impl SubscriptionConsumer
Sourcepub fn read_rows(
engine: &StandardEngine,
db_subscription_id: SubscriptionId,
last_consumed_key: Option<&EncodedKey>,
batch_size: usize,
) -> Result<(Columns, Vec<EncodedKey>)>
pub fn read_rows( engine: &StandardEngine, db_subscription_id: SubscriptionId, last_consumed_key: Option<&EncodedKey>, batch_size: usize, ) -> Result<(Columns, Vec<EncodedKey>)>
Read rows from a subscription’s storage.
Returns (columns, row_keys) where row_keys are the encoded keys for deletion.
Sourcepub fn delete_rows(
engine: &StandardEngine,
row_keys: &[EncodedKey],
) -> Result<()>
pub fn delete_rows( engine: &StandardEngine, row_keys: &[EncodedKey], ) -> Result<()>
Delete consumed rows from subscription storage.
