Statistics from the writer’s lifetime.

Fields

batches_received: u64

Number of batches accepted by the background writer loop.

rows_received: u64

Total number of rows accepted by the background writer loop.

batches_sent: u64

Number of batches successfully sent.

rows_sent: u64

Total number of rows across all successful batches.

errors: u64

Total number of failed send attempts (including retries).

batches_failed: u64

Number of batches dropped after all retries were exhausted.

rows_failed: u64

Total number of rows dropped after all retries were exhausted.

batches_spilled: u64

Number of batches that were persisted to the spill directory after all retries were exhausted. Always 0 when the spill feature or ClickHouseConfig::spill_dir is not configured. Spilled batches are counted in batches_failed/rows_failed as well.

rows_spilled: u64

Total number of rows persisted to the spill directory.

max_outstanding_batches: u64

Maximum observed outstanding-batch count submitted to the writer.

Trait Implementations

impl Clone for WriterStats

fn clone(&self) -> WriterStats

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for WriterStats

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

Formats the value using the given formatter.

impl Default for WriterStats

fn default() -> WriterStats

Returns the “default value” for a type.

impl PartialEq for WriterStats

fn eq(&self, other: &WriterStats) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
