Definition of a continuous aggregate.

Fields

name: String

Name of this aggregate (e.g., “metrics_1m”).

source: String

Source collection or aggregate to read from.

bucket_interval: String

Time bucket interval string (e.g., “1m”, “1h”, “1d”).

bucket_interval_ms: i64

Bucket interval in milliseconds (computed from bucket_interval).

group_by: Vec<String>

Columns to GROUP BY (tag/symbol columns).

aggregates: Vec<AggregateExpr>

Aggregate expressions to compute.

refresh_policy: RefreshPolicy

When to refresh.

retention_period_ms: u64

Retention period in milliseconds (0 = infinite, independent of source).

stale: bool

Whether this aggregate is currently stale (schema change invalidation).

Trait Implementations

impl Clone for ContinuousAggregateDef

fn clone(&self) -> ContinuousAggregateDef

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ContinuousAggregateDef

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ContinuousAggregateDef

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<'__msgpack_de> FromMessagePack<'__msgpack_de> for ContinuousAggregateDef

fn read<R: Read<'__msgpack_de>>(reader: &mut R) -> Result<Self, Error>

where Self: Sized,

Reads the MessagePack representation of this value from the provided reader.

impl PartialEq for ContinuousAggregateDef

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

impl Serialize for ContinuousAggregateDef

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl ToMessagePack for ContinuousAggregateDef

fn write<W: Write>(&self, writer: &mut W) -> Result<(), Error>

Writes the MessagePack representation of this value into the provided writer.
