function LocalTablet

inline explicit LocalTablet(
    hybridse::vm::Engine * engine,
    std::shared_ptr< hybridse::vm::CompileInfoCache > sp_cache
)

function ~LocalTablet

inline ~LocalTablet()

function SubQuery

virtual std::shared_ptr< RowHandler > SubQuery(
    uint32_t task_id,
    const std::string & db,
    const std::string & sql,
    const Row & row,
    const bool is_procedure,
    const bool is_debug
) override

Parameters:

• task_id id of task

• db name of database

• sql represents a sql string if is_procedure is ture, or represents a procedure name

• row request row

• is_procedure whether sql is a procedure or not

• is_debug whether printing debug information while running

Return: Return query result row as RowHandler pointer

Reimplements: hybridse::vm::Tablet::SubQuery

Run a task in request mode locally

function SubQuery

virtual std::shared_ptr< TableHandler > SubQuery(
    uint32_t task_id,
    const std::string & db,
    const std::string & sql,
    const std::set< size_t > & common_column_indices,
    const std::vector< Row > & in_rows,
    const bool request_is_common,
    const bool is_procedure,
    const bool is_debug
)

Parameters:

• task_id id of task

• db name of database

• sql represents a sql string if is_procedure is ture, or represents a procedure name

• common_column_indices a set of common column indices

• in_rows a batch of request rows

• request_is_common whether request is common or not

• is_procedure whether run procedure or not

• is_debug whether printing debug information while running

Return: Return query result rows as TableHandler pointer

Reimplements: hybridse::vm::Tablet::SubQuery
