Member Data Documentation

begin

void *(* s_mysql_bulk_data_load::begin) (THD *thd, const TABLE *table, size_t keynr, size_t data_size, size_t memory, size_t num_threads)

Begin Loading bulk data to SE.

Parameters

[in,out]	thd	session THD
[in]	table	MySQL TABLE
[in]	keynr	key number, identifying the index being loaded.
[in]	data_size	total data size to load
[in]	memory	SE memory to be used
[in]	num_threads	Number of concurrent threads

Returns

SE bulk load context or nullptr in case of an error.

close_blob

bool(* s_mysql_bulk_data_load::close_blob) (THD *thd, void *load_ctx, const TABLE *table, Blob_context blob_ctx, unsigned char *blobref, size_t thread)

Close the blob.

Parameters

[in,out]	thd	session THD
[in,out]	load_ctx	SE load context returned by begin()
[in]	table	MySQL TABLE
[in]	blob_ctx	a blob context object to insert a blob.
[out]	blobref	buffer to hold blob reference
[in]	thread	current thread number

Returns

true if successful.

end

bool(* s_mysql_bulk_data_load::end) (THD *thd, void *ctx, const TABLE *table, bool error)

End Loading bulk data to SE.

Called at the end of bulk load execution, even if begin or load calls failed.

Parameters

[in,out]	thd	session THD
[in,out]	ctx	SE load context
[in]	table	MySQL TABLE
[in]	error	true, if exiting after error

Returns

true if successful.

get_se_memory_size

size_t(* s_mysql_bulk_data_load::get_se_memory_size) (THD *thd, const TABLE *table)

Get available buffer pool memory for bulk load operations.

Parameters

[in,out]	thd	session THD
[in]	table	MySQL TABLE

Returns

buffer pool memory available for bulk load.

is_table_supported

bool(* s_mysql_bulk_data_load::is_table_supported) (THD *thd, const TABLE *table)

Check if a table is supported by the bulk load implementation.

Parameters

[in,out]	thd	session THD
[in]	table	MySQL TABLE

Returns

true if table is supported.

load

bool(* s_mysql_bulk_data_load::load) (THD *thd, void *ctx, const TABLE *table, const Rows_mysql &sql_rows, size_t thread, Bulk_load::Stat_callbacks &wait_cbks)

Load a set of rows to SE table by one thread.

Parameters

[in,out]	thd	session THD
[in,out]	ctx	SE load context returned by begin()
[in]	table	MySQL TABLE
[in]	sql_rows	row data to load
[in]	thread	current thread number
[in]	wait_cbks	wait stat callbacks

Returns

true if successful.

open_blob

bool(* s_mysql_bulk_data_load::open_blob) (THD *thd, void *load_ctx, const TABLE *table, Blob_context &blob_ctx, unsigned char *blobref, size_t thread)

Create a blob context object to insert a blob.

Parameters

[in,out]	thd	session THD
[in,out]	load_ctx	SE load context returned by begin()
[in]	table	MySQL TABLE
[out]	blob_ctx	a blob context object to insert a blob.
[out]	blobref	buffer to hold blob reference
[in]	thread	current thread number

Returns

true if successful.

write_blob

bool(* s_mysql_bulk_data_load::write_blob) (THD *thd, void *load_ctx, const TABLE *table, Blob_context blob_ctx, unsigned char *blobref, size_t thread, const unsigned char *data, size_t data_len)

Write data into a blob.

Parameters

[in,out]	thd	session THD
[in,out]	load_ctx	SE load context returned by begin()
[in]	table	MySQL TABLE
[in]	blob_ctx	a blob context object to insert a blob.
[out]	blobref	buffer to hold blob reference
[in]	thread	current thread number
[in]	data	blob data to be written
[in]	data_len	length of blob data to be written (in bytes);

Returns

true if successful.
