There’s a lot of talk on the web about scalability. Making web applications scale is not easy. The modern web architecture has so many moving parts. How can we grapple with the underlying problem?
Also: Why Are MySQL DBAs So Hard to Find?
The LAMP stack scales well
The truth that is half right. True there are a lot of moving parts, and a lot to setup. The internet stack made up of Linux, Apache, MySQL & PHP. LAMP as it’s called, was built to be resilient, dynamic, and scalable. It’s essentially why Amazon works. Why what they’re doing is possible. Windows & .NET …
[Read more]Memcache access for MySQL Cluster (or NDBCluster) provides faster access to the data because it avoids the SQL parsing overhead for simple lookups – which is a great feature. But what happens if I try to get multiple records via memcache API (multi-GET) and via SQL (SELECT with IN())? I’ve encountered this a few times now, so I decided to blog about it. I did a very simple benchmark with the following script:
#!/bin/bash
mysql_server="192.168.56.75"
mc_server="192.168.56.75"
mysql_cmd="mysql -h${mysql_server} --silent --silent"
mysql_schema="percona"
mysql_table="memcache_t"
mc_port=11211
mc_prefix="mt:"
function populate_data () {
nrec=$1
$mysql_cmd -e "delete from ${mysql_table};" $mysql_schema > /dev/null 2>&1
for rec in `seq 1 $nrec`
do
$mysql_cmd -e "insert into ${mysql_table} values ($rec, repeat('a',10), 0, 0);" $mysql_schema > /dev/null 2>&1
done
}
function mget_via_sql() {
nrec=$1
in_list=''
for rec in …[Read more]
I made a new tutorial for how to use MySQL to develop Big Data
Applications. This is a 'Udacity'/explaining-on-paper style of
video which I hope you will enjoy and find helpful.
Please 'like' or retweet if you feel it is informative.
As I mentioned in a previous post that I’d mention how I resolved some additional missing include files when building MySQL on Windows.
In this post I cover 4 missing header files, as they are all related and have to do with polling, and headers (and functions) from libevent, and in the folder /sys. I’m not sure if one should even use these functions from libevent on Windows, as these are not needed for Windows, and may not be beneficial either (that last part I’ve just read briefly about, so I’d need to that a bit more myself to be 100%), but including the headers won’t hurt, as it doesn’t hurt if they don’t exist.
At any rate, here were the 4 related missing header file warnings:
-- Looking for include file sys/devpoll.h -- Looking for include file sys/devpoll.h - not found -- Looking for include file sys/devpoll.h -- Looking for include file …[Read more]
