Struct MutableMemtables 

pub(crate) struct MutableMemtables {
    partitions: TimePartitions,
    has_skip_wal_writes: AtomicBool,
}

Mutable time partitions and their shared write state.

Version clones share this object. Freezing creates a new object so writes to the new mutable memtables cannot change the old version’s state.

Fields

partitions: TimePartitions

has_skip_wal_writes: AtomicBool

Set before installation because failed writes may install some rows.

Implementations

impl MutableMemtables

fn new(partitions: TimePartitions) -> Self

pub(crate) fn mark_skip_wal_writes(&self)

Marks that these memtables may contain skip-WAL writes.

fn has_skip_wal_writes(&self) -> bool

pub(crate) fn write(&self, kvs: &KeyValues) -> Result<()>

Writes key values to the mutable time partitions.

pub(crate) fn write_bulk(&self, part: BulkPart) -> Result<()>

Writes a bulk part to the mutable time partitions.

pub(crate) fn is_empty(&self) -> bool

Returns whether all mutable time partitions are empty.

pub(crate) fn memtable_builder(&self) -> &MemtableBuilderRef

Returns the memtable builder.

pub(crate) fn next_memtable_id(&self) -> MemtableId

Returns the next memtable ID.

pub(crate) fn part_duration(&self) -> Duration

Returns the time partition duration.

pub(crate) fn new_with_part_duration( &self, part_duration: Option<Duration>, memtable_builder: Option<MemtableBuilderRef>, ) -> TimePartitions

Creates empty time partitions with an optional new duration and builder. The returned partitions do not share data or write state with this object.

pub(crate) fn memory_usage(&self) -> usize

Returns the mutable memory usage.

pub(crate) fn series_count(&self) -> usize

Returns the number of time series in mutable time partitions.

fn num_rows(&self) -> u64

fn num_partitions(&self) -> usize

fn list_memtables(&self, memtables: &mut Vec<MemtableRef>)

Trait Implementations

impl Debug for MutableMemtables

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
