Available on crate feature bulk-load-profile only.

Bulk-load write timing statistics collected by a bulk-load request.

These counters are intended for benchmarking and diagnostics. They separate time spent in bulk-load packet draining from lower-level connection writes and flushes without changing bulk-load behavior.

Fields

write_packets_elapsed: Duration

Time spent inside bulk-load packet drain attempts.

write_to_wire_calls: u64

Number of times bulk-load packet draining wrote to the connection.

write_to_wire_elapsed: Duration

Time spent awaiting lower-level connection writes from bulk load.

write_to_wire_payload_bytes: u64

Payload bytes passed to lower-level connection writes from bulk load.

max_write_to_wire_elapsed: Duration

Slowest lower-level connection write awaited by bulk load.

max_write_to_wire_payload_bytes: usize

Largest payload passed to a lower-level connection write from bulk load.

flush_calls: u64

Number of bulk-load flushes.

flush_elapsed: Duration

Time spent awaiting bulk-load flushes.

max_flush_elapsed: Duration

Slowest explicit flush awaited by bulk load.

finalize_elapsed: Duration

Time spent finalizing the bulk-load request.

finalize_write_to_wire_elapsed: Duration

Time spent awaiting the final EndOfMessage packet write.

finalize_flush_elapsed: Duration

Time spent awaiting the final explicit flush.

finalize_result_elapsed: Duration

Time spent waiting for the server result after final bulk packet flush.

connection_write: BulkLoadConnectionWriteStats

Breakdown of bulk-load connection writes below the coarse write_to_wire aggregate.

direct_packet_write: BulkLoadDirectPacketWriteStats

Experimental raw-bulk direct packet write statistics.

Trait Implementations

impl Clone for BulkLoadWriteTimingStats

fn clone(&self) -> BulkLoadWriteTimingStats

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BulkLoadWriteTimingStats

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

Formats the value using the given formatter.

impl Default for BulkLoadWriteTimingStats

fn default() -> BulkLoadWriteTimingStats

Returns the “default value” for a type.

impl PartialEq for BulkLoadWriteTimingStats

fn eq(&self, other: &BulkLoadWriteTimingStats) -> 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.
