Previously: For a given level the algo knows the number of pages in the requested range and the number of records on the leftmost and the rightmost page. Then it assumes all pages in between contain the average between the two border pages and multiplies this average number by the number of intermediate pages. With this change: Same idea, but peek a few (10) of the intermediate pages to get a better estimate of the average number of records per page. If there are less than 10 intermediate pages then all of them will be scanned and the result will be precise, not an estimation. In the bug report one of the examples has a btree with a snippet of the leaf level like this: page1(899 records), page2(1 record), page3(1 record), page4(1 record) so when trying to estimate, the previous algo, assumed there are average (899+1)/2=450 records per page which went terribly wrong. With this change page2 and page3 will be read and the exact number of records will be returned. Approved by: Sunny (rb://401)	Vasil Dimov	13 years ago

Merge Revision revid:marko.makela@oracle.com-20100810102248-xrdjie2de4r9h3ed from MySQL InnoDB Original revid:marko.makela@oracle.com-20100810102248-xrdjie2de4r9h3ed Original Authors: Marko Mäkelä <marko.makela@oracle.com> Original commit message: Bug#54914: InnoDB: performance drop with innodb_change_buffering=all Reduce ibuf_mutex and ibuf_pessimistic_insert_mutex contention further. Protect ibuf->empty by the insert buffer root page latch, not ibuf_mutex. ibuf_tree_root_get(): Assert that ibuf_mutex is owned by the caller. Assert that the stamped page number is correct. Assert that ibuf->empty agrees with the root page. ibuf_size_update(): Do not update ibuf->empty. ibuf_init_at_db_start(): Update ibuf->empty while holding the root page latch. ibuf_add_free_page(): Return TRUE/FALSE instead of DB_SUCCESS/DB_STRONG_FAIL. ibuf_remove_free_page(): Release ibuf_pessimistic_insert_mutex as early as possible. ibuf_contract_ext(): Rely on a dirty read of ibuf->empty, unless the server is being shut down. Never acquire ibuf_mutex. Eliminate n_stored. ibuf_contract_after_insert(): Never acquire ibuf_mutex. Perform dirty reads of ibuf->size and ibuf->max_size. ibuf_insert_low(): Only acquire ibuf_mutex for mode==BTR_MODIFY_TREE. Perform dirty reads of ibuf->size and ibuf->max_size. Update ibuf->empty while holding the root page latch. ibuf_delete_rec(): Update ibuf->empty while holding the root page latch. ibuf_is_empty(): Release ibuf_mutex earlier.	Marko Mäkelä	13 years ago

This does not fix the update regression in Bug #54914, but it does speed up the execution for innodb_change_buffering=inserts. ibuf_add_ops(), ibuf_merge_or_delete_for_page(), ibuf_delete_for_discarded_space(): Use atomic built-ins instead of ibuf_mutex, when available. ibuf_add_free_page(), ibuf_remove_free_page(), ibuf_contract_ext(): Release ibuf_mutex earlier. ibuf_free_excess_pages(): Release ibuf_mutex before a conditional branch. ibuf_insert_low(): Release ibuf_mutex before a conditional branch. Create ibuf_entry before re-acquiring ibuf_mutex. Simplify a loop to reduce code footprint. Release ibuf_mutex before mtr_commit() [btr_pcur_close()]. ibuf_is_empty(): Release ibuf_mutex before mtr_commit().	Marko Mäkelä	13 years ago
