Struct ExternalStorageTable

pub struct ExternalStorageTable {
    table_id: TableId,
    table_name: String,
    schema_name: String,
    database_name: String,
    table_reader: ExternalTableReaderImpl,
    schema: Schema,
    pk_order_types: Vec<OrderType>,
    pk_indices: Vec<usize>,
}

This struct represents an external table to be read during backfill

Fields

table_id: TableId

Id for this table.

table_name: String

The normalized name of the table, e.g. dbname.schema_name.table_name.

schema_name: String

database_name: String

table_reader: ExternalTableReaderImpl

schema: Schema

The schema of the output columns, i.e., this table VIEWED BY some executor like RowSeqScanExecutor. todo: the schema of the external table defined in the CREATE TABLE DDL

pk_order_types: Vec<OrderType>

pk_indices: Vec<usize>

Indices of primary key. Note that the index is based on the all columns of the table.
