InnoDB crash recovery used a special type of mem_heap_t that allocates backing store from the buffer pool. That incurred a significant overhead, leading to underutilization of memory, and limiting the maximum contiguous allocated size of a log record. recv_sys_t::blocks: A linked list of buf_block_t that are allocated by buf_block_alloc() for redo log records. Replaces recv_sys_t::heap. We repurpose buf_block_t::unzip_LRU for linking the elements. recv_sys_t::max_log_blocks: Renamed from recv_n_pool_free_frames. recv_sys_t::max_blocks(): Accessor for max_log_blocks. recv_sys_t::alloc(): Allocate memory from the current recv_sys_t::blocks element, or allocate another block. In debug builds, various free() member functions must be invoked, because we repurpose buf_page_t::buf_fix_count for tracking allocations. recv_sys_t::free_corrupted_page(): Renamed from recv_recover_corrupt_page() recv_sys_t::is_memory_exhausted(): Renamed from recv_sys_heap_check() recv_sys_t::pages and its elements are allocated directly by the system memory allocator. recv_parse_log_recs(): Remove the parameter available_memory. We rename some variables 'store_to_hash' to 'store', because recv_sys.pages is not actually a hash table. This is joint work with Thirunarayanan Balathandayuthapani. |
