Struct AlterLogicalTableValidator

pub struct AlterLogicalTableValidator<'a> {
    physical_table_id: TableId,
    alters: Vec<&'a AlterTableExpr>,
}

AlterLogicalTableValidator validates the alter logical expressions.

Fields

physical_table_id: TableId

alters: Vec<&'a AlterTableExpr>

Implementations

impl<'a> AlterLogicalTableValidator<'a>

pub fn new(physical_table_id: TableId, alters: Vec<&'a AlterTableExpr>) -> Self

fn validate_schema(&self) -> Result<()>

Validates all alter table expressions have the same schema and catalog.

fn validate_alter_kind(&self) -> Result<()>

Validates that all alter table expressions are of the supported kind. Currently only supports AddColumns operations.

fn table_names(&self) -> Vec<TableReference<'_>>

async fn validate_physical_table( &self, table_metadata_manager: &TableMetadataManagerRef, ) -> Result<(DeserializedValueWithBytes<TableInfoValue>, PhysicalTableRouteValue)>

Validates that the physical table info and route exist.

This method performs the following validations:

1. Retrieves the full table info and route for the given physical table id
2. Ensures the table info and table route exists
3. Verifies that the table route is actually a physical table route, not a logical one

Returns a tuple containing the validated table info and physical table route.

async fn validate_logical_table_routes( &self, table_route_manager: &TableRouteManager, table_ids: &[TableId], ) -> Result<()>

Validates that all logical table routes have the same physical table id.

This method performs the following validations:

1. Retrieves table routes for all the given table ids.
2. Ensures that all retrieved routes are logical table routes (not physical)
3. Verifies that all logical table routes reference the same physical table id.
4. Returns an error if any route is not logical or references a different physical table.

pub async fn validate( &self, table_metadata_manager: &TableMetadataManagerRef, ) -> Result<ValidatorResult>

Validates the alter logical expressions.

This method performs the following validations:

1. Validates that all alter table expressions have the same schema and catalog.
2. Validates that all alter table expressions are of the supported kind.
3. Validates that the physical table info and route exist.
4. Validates that all logical table routes have the same physical table id.

Returns a ValidatorResult containing the validation results.
