in the package from mariadb there is no compression avalible,
it is possible to have compression in mariadb, for this it is required to compile mariadb.
here are the linux commands i have used to compile it and package it into a deb repository.
sudo su - cd /opt mkdir mariadb apt-get install build-essential devscripts dpkg-sig git apt-get install libsnappy-dev liblzo2-dev libbz2-dev liblzma-dev liblz4-dev # when you have these libs it enables compression automatically apt-get install bison chrpath cmake debhelper dh-apparmor dpatch libaio-dev libboost-dev libjudy-dev libkrb5-dev libncurses5-dev libpam0g-dev libreadline-gplv2-dev libssl-dev po-debconf psmisc zlib1g-dev libcrack2-dev libjemalloc-dev git clone --recursive https://github.com/MariaDB/server.git cd server git checkout 10.1 ./debian/autobake-deb.sh cd .. mkdir notsig # optional to have a backup of non signed debs cp ./*maria* ./notsig/ # optional to have a backup of non signed debs mkdir repo cp -r notsig repo/files cd repo apt-get install rng-tools # this is required if system says not enough entropy to generate rsa key below. gpg --gen-key # make rsa only key with 4096 bits without a passphraze gpg --list-keys #see those numbers that come after 'pub 4096R/' in the list gpg --output keyFile --armor --export 9D0234BB dpkg-sig -k 'Full Name (comment) <email@email.com>' --sign builder ./*.deb #waht comes after uid in gpg key list, not sure about this command: why i need to add some name to signing, why even after signing apt told me my debs are not trusted cat keyFile | apt-key add - for ubuntu 14 mkdir -p dists/trusty/binary/binary-amd64/Packages apt-ftparchive packages ./files > dists/trusty/binary/binary-amd64/Packages gzip -c dists/trusty/binary/binary-amd64/Packages > dists/trusty/binary/binary-amd64/Packages.gz apt-ftparchive release ./files > dists/trusty/binary/binary-amd64/Release gpg --clearsign -o InRelease dists/trusty/binary/binary-amd64/Release gpg -abs -o dists/trusty/binary/binary-amd64/Release.gpg dists/trusty/binary/binary-amd64/Release or for ubuntu 16: mkdir -p dists/xenial/binary/binary-amd64 apt-ftparchive packages ./files > dists/xenial/binary/binary-amd64/Packages gzip -c dists/xenial/binary/binary-amd64/Packages > dists/xenial/binary/binary-amd64/Packages.gz apt-ftparchive release ./files > dists/xenial/binary/binary-amd64/Release gpg --clearsign -o InRelease dists/xenial/binary/binary-amd64/Release gpg -abs -o dists/xenial/binary/binary-amd64/Release.gpg dists/xenial/binary/binary-amd64/Release for ubuntu 14 add to /etc/apt/sources.list: deb [arch=amd64 trusted=yes] file:/root/mariadb/repo trusty binary for ubuntu 16 nano /etc/apt/sources.list.d/mariadb-local.list add: deb [arch=amd64 trusted=yes] file:/opt/mariadb/repo xenial binary then: chmod 755 -R /opt/mariadb apt update
my /etc/mysql/my.cnf
it is a large server with 32g ram and ssd (for temporary processing of large amounts of data).
it is very fast , one problem I have found is that MariaDB/MySQL gives one thread per connection
from MediaWiki settings:
# MySQL table options to use during installation or update
$wgDBTableOptions = “ENGINE=InnoDB, DEFAULT CHARSET=utf8mb4 ROW_FORMAT=COMPRESSED”;
if I use utf8mb4, to have varchar 255 length columns, table type must be ROW_FORMAT=COMPRESSED or ROW_FORMAT=DYNAMIC
otherwise, max length is about 75
