Problem:
=======
- insert..select statement on partition table fails to use
bulk insert for the transaction.
Solution:
========
- Enable the bulk insert operation for insert..select
statement for partition table.
Problem:
=======
InnoDB wrongly stores the primary key field in externally
stored off page during bulk insert operation. This leads
to assert failure.
Solution:
========
row_merge_buf_blob(): Should store the primary key fields
inline. Store the variable length field data externally
based on the row format of the table.
row_merge_buf_write(): check whether the record size exceeds
the maximum record size.
row_merge_copy_blob_from_file(): Construct the tuple based on
the variable length field
- This commit is different from 10.6 commit c438284863.
Due to Commit 045757af4c (MDEV-24621),
InnoDB does buffer and pre-sort the records for each index, and build
the indexes one page at a time.
Multiple large insert ignore statment aborts the server during bulk
insert operation. Problem is that InnoDB merge record exceeds
the page size. To avoid this scenario, InnoDB should catch
too big record while buffering the insert operation itself.
row_merge_buf_encode(): returns length of the encoded index record
row_merge_buf_write(): Catches the DB_TOO_BIG_RECORD earlier and
returns error
