Enum AnnotationFamily 

pub enum AnnotationFamily {
    Semantic,
    RepartitionHint,
}

A family of annotation table options: pure metadata markers that no region consumes. Setting or unsetting them only rewrites the table’s extra_options, so the alter skips region dispatch entirely.

Variants

Semantic

greptime.semantic.* options (see the semantic module).

RepartitionHint

repartition.column.hint, consumed by the auto-repartition planner.

Implementations

impl AnnotationFamily

pub fn namespace(self) -> &'static str

The key namespace: a prefix for Self::Semantic, the exact key for Self::RepartitionHint.

pub fn of_key(key: &str) -> Option<Self>

pub fn allows_logical_tables(self) -> bool

Whether this family may be altered on logical metric tables. Only families whose values nothing on the physical side consumes qualify; the repartition hint drives physical region repartitioning.

pub fn requires_single_key(self) -> bool

Whether this family’s SET/UNSET batch must contain exactly one key. The repartition hint is a single marker; a batch with several hint entries (duplicates included) has no meaningful order.

pub fn mixed_batch_error(self) -> String

The error for a SET/UNSET batch mixing this family with other options.

Trait Implementations

impl Clone for AnnotationFamily

fn clone(&self) -> AnnotationFamily

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AnnotationFamily

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for AnnotationFamily

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for AnnotationFamily

fn eq(&self, other: &AnnotationFamily) -> 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 AnnotationFamily

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
