The move to this model provides for more frequent milestone releases, with each milestone proceeding through a small number of releases having a focus on a specific subset of thoroughly tested features.Following the releases for one milestone, development proceeds with the next milestone; that is, another small number of releases that focuses on the next small set of features, also thoroughly tested.I'm attempting to switch to row-based replication but cannot get it (either default MIXED mode or forced ROW) to work.I'm having two show-stopper problems when RBR is active that I don't have at all when it is not: 1.Even if I solved that, I'd have to use the surrogate in partitioning - which more or less defeats the purpose of partitioning by lopsiding the partitions. A long composite key is also not an option because: In Inno DB tables, having a long PRIMARY KEY wastes a lot of space.(See Section 13.6.10, “Inno DB Table and Index Structures”.) --- Inno DB, the records in nonclustered indexes (also called secondary indexes) contain the primary key columns for the row that are not in the secondary index.
It completely hamstrings any large volume setup - in my case, my only decent primary key is a surrogate key - and that's untenable because of the locking and lost concurrency (even with lock_mode = 2). to improve query times)" PK is not really an option for them since there are no short unique columns.
Inno DB uses this primary key value to search for the row in the clustered index.
If the primary key is long, the secondary indexes use more space, so it is advantageous to have a short primary key.
If I do "stop slave" and then "start slave" again it immediately has an error like this, seemingly for random tables that have been written to (not one in particular): Could not execute Write_rows event on table XXX; Duplicate entry 'YYY' for key 'ZZZ', Error_code: 1062; handler error HA_ERR_FOUND_DUPP_KEY; the event's master log binlog.000003, end_log_pos 704849 I have scoured the bug reports and found nothing to explain either of these. I'm running the Linux (AMD64 / Intel EM64T) build of 5.1.25 on a xeon box...nothing that unusual about my environment or database. If nobody has ideas I suppose I will file bug reports, but these are such general failures I don't know what to say in them other than "it don't work".
Only thing I could think of is that my app does some large insert delayed ...
