Updates that can be applied to view metadata in a commit operation

This enum represents all possible modifications that can be made to view metadata:

• UUID assignment (only during view creation)
• Format version updates
• Schema modifications
• Location and property updates
• Version management (add versions, set current version)

Type Parameters

• T - The materialization type for the view, typically Option<()> for regular views or FullIdentifier for materialized views

Each variant includes the necessary data for that specific update type. Updates are applied atomically as part of a commit operation.

Variants

AssignUUID

Assigning a UUID to a table/view should only be done when creating the table/view. It is not safe to re-assign the UUID if a table/view already has a UUID assigned

Fields

uuid: String

new uuid

UpgradeFormatVersion

Update format version

Fields

format_version: i32

New format version

AddSchema

The highest assigned column ID for the table. This is used to ensure columns are always assigned an unused ID when evolving schemas. When omitted, it will be computed on the server side.

Fields

schema: Schema

Schema to add

last_column_id: Option<i32>

New last column id

SetLocation

Set a new location for the table

Fields

location: String

New Location

SetProperties

Set table properties

Fields

updates: HashMap<String, String>

Properties to set

RemoveProperties

Remove table properties

Fields

removals: Vec<String>

Properties to remove

AddViewVersion

Add a new version to the view

Fields

view_version: Version<T>

Version to add

SetCurrentViewVersion

The view version id to set as current, or -1 to set last added view version id

Fields

view_version_id: i64

The id to set

Trait Implementations

impl<T: Clone + Materialization> Clone for ViewUpdate<T>

fn clone(&self) -> ViewUpdate<T>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: Debug + Materialization> Debug for ViewUpdate<T>

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

Formats the value using the given formatter.

impl<'de, T> Deserialize<'de> for ViewUpdate<T>

where T: Deserialize<'de> + Materialization,

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<T: PartialEq + Materialization> PartialEq for ViewUpdate<T>

fn eq(&self, other: &ViewUpdate<T>) -> 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<T> Serialize for ViewUpdate<T>

where T: Serialize + Materialization,

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
