Struct Batch

Source 
pub struct Batch { /* private fields */ }
Expand description

An atomic write batch

Allows atomically writing across partitions inside the Keyspace.

Implementations§

Source§

impl Batch

Source

pub fn with_capacity(keyspace: Keyspace, capacity: usize) -> Self

Initializes a new write batch with preallocated capacity.

Source

pub fn durability(self, mode: Option<PersistMode>) -> Self

Sets the durability level.

Source

pub fn insert<K: Into<UserKey>, V: Into<UserValue>>( &mut self, p: &PartitionHandle, key: K, value: V, )

Inserts a key-value pair into the batch

Source

pub fn remove<K: Into<UserKey>>(&mut self, p: &PartitionHandle, key: K)

Adds a tombstone marker for a key

Source

pub fn commit(self) -> Result<()>

Commits the batch to the Keyspace atomically

§Errors

Will return Err if an IO error occurs.
