FAQ
I wrote a simple (synthetic) benchmark to keep track how the MySQL
performance in Go (database/sql package) improves by time.
Right now the benchmark is very simple but I'll keep extending it.
I compared the performance of the two MySQL drivers "Go-MySQL-Driver" (
https://github.com/Go-SQL-Driver/MySQL ) and the "godrv" of "mymysql"
( https://github.com/ziutek/mymysql ).
But I also wrote an equivalent (at least I tried) benchmark in Java7 to
compare the performance to a mature library like JDBC and a highly
optimized driver like "MySQL Connector/J".

Be invited to post your own results, extend / improve the benchmark or even
help improving the performance in go.
Especially for multiple row queries (SimpleQuery / PreparedQuery) i wonder
how they could be improved. I'm not sure why go performs so bad compared to
Java there.

    Hm. Did you ever commit after all those SELECTs? When you do
    a SELECT with MySQL using InnoDb, you're within a transaction, and
    the database will not visibly change underneath you. "The default
    transaction level for MySQL InnoDB is REPEATABLE READ".
    Each time you do another SELECT within a transaction, the
    database either has to lock the result set or make a temporary
    copy of the rows you just read. So when you do 10,000 SELECT
    operations, each of which returns 100 rows, you've forced
    MySQL to make temporary copies of 10,000,000 rows.
    That can slow down the database engine.

    I think Java' driver has autocommit=true by default, and Go's
    driver has it set to false. Set it explicitly in both test
    cases and see what happens.

    autocommit is on by default, but you are right, this should be set
    explicitly.

    The multi-row-mystery seems to be solved: While Go-MySQL-Driver reads just
    one row on every Rows.Next() from the buffered stream, MySQL Connector/J
    seems to use some sort of prefetching. If you turn this behavior off by
    adding "useReadAheadInput=false” to the DSN the performance drops to
    roughly 2100 queries/second. I'll try so add a similar (of course
    configurable) behavior to Go-MySQL-Driver.

    Mh no, no prefetching. I just browsed the source. "ReadAheadInputStream" is
    just a buffered stream like Go's bufio, but it claims to be non-blocking.

    Thanks for your work!

    Your benchmark has clearly showed that I need to optimize mymysql. The
    optimization was:
    1. Reducing a number of allocations in protocol handling code.
    2. Remove using of reflection in godrv.
    3. Implement driver.Execer

    After that Go-MySQL-Driver and mymysql/godrv benchmarks are more
    similar.

    There are my results (queries/second):

    SimpleQuery
    godrv: 2017 Go-MySQL: 1764

    PreparedQuery
    godrv: 2527 Go-MySQL: 1989

    AutoQueryRow
    godrv: 5514 Go-MySQL: 5802

    SimpleQueryRow
    godrv: 5668 Go-MySQL: 5910

    PreparedQueryRow
    godrv: 12491 Go-MySQL: 13201

    SimpleExec
    godrv: 16346 Go-MySQL: 16120

    PreparedExec:
    godrv: 17337 Go-MySQL: 16459

    Wow definitely improved!
    Still not beating Go-MySQL-Driver on my setup though (usual best-of-2
    mode). The results are below.

    My turn to optimize now ;)

    The JDBC results for (Simple|Prepared)Query made me think. I'm also
    reworking my stream I/O right now.
    I'll run another benchmark-round soon. Feel free to contribute to the
    benchmark suite.

    Go-MySQl-Driver 3923 | mymysql 3216 queries/second

    PreparedQuery:
    Go-MySQl-Driver 3716 | mymysql 4122 queries/second <- wow!

    AutoQueryRow:
    Go-MySQl-Driver 7748 | mymysql 6855 queries/second

    SimpleQueryRow:
    Go-MySQl-Driver 15075 | mymysql 6970 queries/second

    PreparedQueryRow:
    Go-MySQl-Driver 15539 | mymysql 14238 queries/second

    SimpleExec:
    Go-MySQl-Driver 29238 | mymysql 27306 queries/second

    Schmidt,
    I plan to use go-sql-driver in my production environment in a few weeks.
    Is there a stable release avaible now?
    As the product is due to be dilivered to my clients, so I hope that the
    version of go-sql-driver is as stable as possible.
    Could you please give me some pieces of advice?
    Thanks in advance.

    Schmidt,
    Julien please, Schmidt is my surname ;)

    I rewrote a lot code in the last days. Although it passed my usual test
    stack I would recommend to wait some time ("a few weeks" should be enough)
    to feel certain that no bug slipped in.
    In general I consider the current code base as safe for production use. I
    use it personally in production without any problems. But it's still tagged
    as "beta" because it's not feature complete yet.

    Is there a stable release avaible now?
    As the product is due to be dilivered to my clients, so I hope that the
    version of go-sql-driver is as stable as possible.
    Could you please give me some pieces of advice?
    Thanks in advance.

    Julien,
    Sorry, I thought it is polite to call you by your family name.
    I will wait until everything is ready.
    Thanks for your.advice.

    Schmidt,
    Julien please, Schmidt is my surname ;)

    I rewrote a lot code in the last days. Although it passed my usual test
    stack I would recommend to wait some time ("a few weeks" should be enough)
    to feel certain that no bug slipped in.
    In general I consider the current code base as safe for production use. I
    use it personally in production without any problems. But it's still tagged
    as "beta" because it's not feature complete yet.
