Detailed Description

Class that caches RTree index tuples made from a single cluster index page scan, and then insert into corresponding index tree.

Member Typedef Documentation

Tuples

using ddl::RTree_inserter::Tuples = std::vector<dtuple_t *, ut::allocator<dtuple_t *> >

private

Cache index rows made from a cluster index scan.

Usually for rows on single cluster index page

Member Function Documentation

add_to_batch()

void ddl::RTree_inserter::add_to_batch ( const dtuple_t *  row, const row_ext_t *  ext  )

noexcept

Caches an index row into index tuple vector.

Parameters

[in]	row	Table row
[in]	ext	Externally stored column prefixes, or nullptr

batch_insert()

dberr_t ddl::RTree_inserter::batch_insert ( trx_id_t  trx_id, Latch_release &&  latch_release  )

noexcept

Insert the rows cached in the batch (m_dtuples).

Parameters

[in]	trx_id	Transaction id.
[in,out]	latch_release	Called when a log free check is required.

Returns

DB_SUCCESS if successful, else error number

inlinenoexcept

Get the index instance.

Returns

the index instance.

is_initialized()

bool ddl::RTree_inserter::is_initialized ( )

inlinenoexcept

Returns

true if initialization succeeded .
