[Maria-discuss] MariaDB-10.2.11 Long Time To Start
by Michael Caplan 15 Mar '19

15 Mar '19

Hi, I'm setting up a replication slave based off of MySQL 5.6. There are a large number of tables (400K). The MySQL 5.6 master takes around 10 minutes to start up, where the new MariaDB 10.2 slave takes close to 30 minutes. What is making the startup take soo long? In the below mysql log, you can see in the startup sequence between "Highest supported file format is Barracuda." and "InnoDB: 128 out of 128 rollback segments are active." the startup process takes the majority of its time: 2018-01-07 9:38:15 139980432365760 [Note] InnoDB: Mutexes and rw_locks use GCC atomic builtins 2018-01-07 9:38:15 139980432365760 [Note] InnoDB: Uses event mutexes 2018-01-07 9:38:15 139980432365760 [Note] InnoDB: Compressed tables use zlib 1.2.8 2018-01-07 9:38:15 139980432365760 [Note] InnoDB: Using Linux native AIO 2018-01-07 9:38:15 139980432365760 [Note] InnoDB: Number of pools: 1 2018-01-07 9:38:15 139980432365760 [Note] InnoDB: Using SSE2 crc32 instructions 2018-01-07 9:38:15 139980432365760 [Note] InnoDB: Initializing buffer pool, total size = 54G, instances = 8, chunk size = 128M 2018-01-07 9:38:18 139980432365760 [Note] InnoDB: Completed initialization of buffer pool 2018-01-07 9:38:18 139918113195776 [Note] InnoDB: If the mysqld execution user is authorized, page cleaner thread priority can be changed.

[Maria-discuss] MariaDB Compile Size
by Tom Jay 21 May '18

21 May '18

Hello, Has anyone got any idea how to reduce the MariaDB install size, when compiling from source? I've had multiple attempts, all with different options such as 'WITHOUT_EXAMPLE_STORAGE_ENGINE=1' and 'FEATURE_SET:STRING=large', for example, but with no effect. The installation size is usually around 2.1 GB, whereas the official Arch package, which also compiles from source, is about 231.78 MB. The official Arch build script is here [https://git.archlinux.org/svntogit/packages.git/tree/trunk/PKGBUILD?h=packa…] and the only difference I can notice is that they delete a lot of stuff afterwards. Is there any reference for stuff that can be deleted after MariaDB has been installed? Thanks.

[Maria-discuss] [question] password input length
by Michal Schorm 16 May '18

16 May '18

Hello everyone, 1) I found out, that passwords longer than 79 characters aren't accepted via password prompt. Is that expected? Morie info and reproducer in RH bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=1566179 -- 2) Another password length cap at 213 characters can be found when using sha256_password authentification plugin. Is that expected too? Morie info and reproducer in RH bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=1566219 -- 3) Different theme: why aren't tests for mariadb-connector-odbc, that can be found on GitHub, packged to the source tarball ? -- Michal Schorm Associate Software Engineer Core Services - Databases Team Red Hat
