Struct HotTablet

pub struct HotTablet {
    pub name: String,
    pub table_name: String,
    pub start_time: Option<Timestamp>,
    pub end_time: Option<Timestamp>,

A tablet is a defined by a start and end key and is explained in https://cloud.google.com/bigtable/docs/overview#architecture and https://cloud.google.com/bigtable/docs/performance#optimization. A Hot tablet is a tablet that exhibits high average cpu usage during the time interval from start time to end time.

Fields

name: String

The unique name of the hot tablet. Values are of the form projects/{project}/instances/{instance}/clusters/{cluster}/hotTablets/\[a-zA-Z0-9_-\]*.

table_name: String

Name of the table that contains the tablet. Values are of the form projects/{project}/instances/{instance}/tables/[_a-zA-Z0-9][-_.a-zA-Z0-9]*.

start_time: Option<Timestamp>

Output only. The start time of the hot tablet.

end_time: Option<Timestamp>

Output only. The end time of the hot tablet.

start_key: String

Tablet Start Key (inclusive).

end_key: String

Tablet End Key (inclusive).

node_cpu_usage_percent: f32

Output only. The average CPU usage spent by a node on this tablet over the start_time to end_time time range. The percentage is the amount of CPU used by the node to serve the tablet, from 0% (tablet was not interacted with) to 100% (the node spent all cycles serving the hot tablet).

Trait Implementations

impl Clone for HotTablet

fn clone(&self) -> HotTablet

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for HotTablet

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

Formats the value using the given formatter.

impl Default for HotTablet

fn default() -> Self

Returns the “default value” for a type.

impl Message for HotTablet

fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

fn clear(&mut self)

Clears the message, resetting all fields to their default.

fn encode(&self, buf: &mut impl BufMut) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message to a buffer.

fn encode_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message to a newly allocated buffer.

fn encode_length_delimited( &self, buf: &mut impl BufMut, ) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message with a length-delimiter to a buffer.

fn encode_length_delimited_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message with a length-delimiter to a newly allocated buffer.

fn decode(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes an instance of the message from a buffer.

fn decode_length_delimited(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes a length-delimited instance of the message from the buffer.

fn merge(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes an instance of the message from a buffer, and merges it into self.

fn merge_length_delimited(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes a length-delimited instance of the message from buffer, and merges it into self.

impl PartialEq for HotTablet

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