@Private
public interface TableProcedureInterface

Procedures that operates on a specific Table (e.g. create, delete, snapshot, ...) must implement this interface to allow the system handle the lock/concurrency problems.

Fields

Modifier and Type	Field	Description
static final TableName	DUMMY_NAMESPACE_TABLE_NAME	Used for acquire/release lock for namespace related operations, just a place holder as we do not have namespace table any more.

Method Summary

Modifier and Type	Method	Description
TableName	getTableName()	Returns the name of the table the procedure is operating on
TableProcedureInterface.TableOperationType	getTableOperationType()	Given an operation type we can take decisions about what to do with pending operations.

Field Details

DUMMY_NAMESPACE_TABLE_NAME

static final TableName DUMMY_NAMESPACE_TABLE_NAME

Used for acquire/release lock for namespace related operations, just a place holder as we do not have namespace table any more.

Method Details

getTableName

TableName getTableName()

Returns the name of the table the procedure is operating on

getTableOperationType

TableProcedureInterface.TableOperationType getTableOperationType()

Given an operation type we can take decisions about what to do with pending operations. e.g. if we get a delete and we have some table operation pending (e.g. add column) we can abort those operations.

Returns:

the operation type that the procedure is executing.
