Aug 6 12:24:24 testserver mysqld: 150806 12:24:24 [Note] /usr/libexec/mysqld (mysqld 10.0.20-MariaDB) starting as process 115096 ... why is this now stdout instead mysql logs? on systemd based distributions that spits now to the global syslog and finally on machines restarting 2 instances every hour for backup reasons it annoys until 10.0.19 or 10.0.20 that was not this way

[Maria-discuss] Some questions about the Aarch64 CI
by Zheng Zhenyu 21 Jan '20

21 Jan '20

Hi MariaDB, Thanks for the greate unconference in Shanghai this week, it is a really useful event for MariaDB newbie like me. We have mentioned that we are willing to donate some ARM resource to the fundation for ARM testing and other purpose in the future. And I have done donated one for POC on 20th Nov, and I can now see a new builder(worker) on: https://buildbot.mariadb.org/#/builders named as ``aarch-fedora-30``, and the version is 2019.11.20, so I guess this could be running on server that I've donated? And seems it is successfully running for few rounds. So I have some questions about the Aarch64 CI: 1. So the jobs are running through docker, so jobs for different OS could be run on this host, right? Is it possible to also enable a CentOS7 job now? 2. As I mentioned in the unconference, we will have an OpenSource OS released soon, and we are looking for possiblities to also make it tested in the upstream, If the answer to the first question is True, we will have to prepare a base docker image for our OS, right? 3. I saw that there is a sponsors site for buildbot: https://buildbot.mariadb.org/#/sponsor , are we able to be on that page too? BR, Kevin Zheng

Hi, I am trying to download the Windows C connector 3.1.6 build to test an SSL issue, however the Windows packages are not available from Connector-c-3.1.6 <https://downloads.mariadb.com/Connectors/c/connector-c-3.1.6/>. On checking the Connector-c-3.1.5 release, the required files are available. Will the 3.16 Windows build be available ? Thanks Kenneth

[Maria-discuss] When do Query Select to Big Table is too slow !
by Ing Angel Cantu 13 Dec '19

Hi. I have problems to make query to a table from the db, is delaying so much (too slow), I don't know whats I need to do, I do some test to my code but is not the problem, is the table. When I make a select to the table marked with red, the response delay 6 or 8 seconds, but, if I do a query to another table the response delay 1 second (fast). Only the table marked with red is delaying. I do this specific query: /select * from FACTURACION where ID_USER='ID_HASH' order by SERVER_DATE limit 1,12;// / I only query the first 12 results order by date, and in the code I make the pagination using "?page=NUMBER" Regards! -- AngelHanielCantuJauregui angel.cantu(a)moneybox.business <mailto:angel.cantu@moneybox.business;> Gerencia | Servicios de Innovacion para Empresas SA de CV Proveemos soluciones para facilitar la administración de tu negocio y garantizar tus próximas vacaciones en compañia de tu familia sin preocupaciones (818) 421 9924 <tel:(818) 421 9924> | (899) 871 1722 <https://wa.me/528998711722> angel.cantu(a)moneybox.business <mailto:angel.cantu@moneybox.business> https://www.moneybox.business 20 de noviembre #300, CP 88780 Reynosa, Tamps, Mexico facebook <https://business.facebook.com/moneyboxco/> twitter <https://twitter.com/moneyboxlatam/> linkedin <https://www.linkedin.com/company/27011448/> instagram <https://www.instagram.com/moneyboxlatam/> <https://www.moneybox.business>

[Maria-discuss] Performance lags with MariaDB built from source
by Nisarg Shah 05 Dec '19

05 Dec '19

System config: OS: Ubuntu 18.04 CPU: 2x Intel Xeon E5-2660 (40 logical cores) RAM: 160GB I built a debug build of MariaDB server 10.5 from the Github source and tried to load and execute the TPC-H benchmarks on it with a database size of 1GB. While loading the data and executing queries, I observed that MariaDB takes an unusually large amount of time (more than 10x compared to other databases like QuickStep or MonetDB) to load the data and execute queries (more than 10 minutes per query, compared to less than a minute for other databases). I'm running the server with following options - ./bin/mysqld --user=nisargs --datadir=/fastdisk/mariadb-server-install-2/data/ --innodb-read-io-threads=40 --innodb-write-io-threads=40 --innodb-buffer-pool-size=16G --innodb-buffer-pool-instances=40 I just wanted to get some eyes on this and check if there is something wrong with the command line options (or whether I can tweak some options to improve performance). I'm just trying to conduct some benchmarking experiments and not very familiar with databases. Thanks Nisarg
