int jf_journal_file_t::all_in_cache

If TRUE, all the "redo data" are in cache (fast rollback can performed simply discarding cache content); if FALSE, some data was already dumped to journal and a rollback record is necessary for this journaled file Definition at line 204 of file jf_journal_file.h. Referenced by jf_journal_file_get_all_in_cache(), jf_journal_file_init(), jf_journal_file_reset(), and jf_journal_file_set_all_in_cache().

jf_cache_file_t jf_journal_file_t::cache_file
