Struct TableSchema 

pub struct TableSchema {
    pub name: String,
    pub arrow_schema: SchemaRef,
    pub primary_key: Vec<String>,
}

Schema definition for a table tracked by the HTAP engine.

Fields

name: String

Table name (must match the OLTP table name).

arrow_schema: SchemaRef

Arrow schema describing the column types.

primary_key: Vec<String>

Column names that form the primary key (required for UPDATE/DELETE propagation).

Implementations

impl TableSchema

pub fn new( name: impl Into<String>, schema: SchemaRef, primary_key: Vec<String>, ) -> Self

Create a new TableSchema.

name must be a valid SQL identifier (see validate_identifier). primary_key is a list of column names that uniquely identify a row; it must be non-empty and every column must exist in schema.

Call TableSchema::validate before passing this to SchemaRegistry::register, or use register directly (it calls validate internally).

pub fn validate(&self) -> Result<(), CoreError>

Validate the schema.

Checks:

1. Table name and all column names are safe SQL identifiers ([A-Za-z0-9_]).
2. At least one primary key column is declared.
3. Every declared primary key column exists in the Arrow schema.

Errors

Returns CoreError::SchemaValidation with a descriptive message if any check fails.
