Configure MySQL for real-time bigdata frontend

Big Data does not always mean NOSQL. Sometimes you have to use a combination of NOSQL databases with Relational databases to get what you want. The key is knowing when (not) to use what.

Usually one clever trick is to use NOSQL databases for backend purposes and relying upon the ACID properties of relational databases (such as MYSQL) for front-end purposes. If you are planning on using MYSQL for such scenario, then configuring it properly is very important for rapid response and effective resource utilization. Here is one such sample configuration that should help you get started.

Put the below content in the /etc/mysql/my.cnf and you are good to go.

#
# The MySQL database server configuration file.
#
# You can copy this to one of:
# - "/etc/mysql/my.cnf" to set global options,
# - "~/.my.cnf" to set user-specific options.
# 
# One can use all long options that the program supports.
# Run program with --help to get a list of available options and with
# --print-defaults to see which it would actually understand and use.
#
# For explanations see
# http://dev.mysql.com/doc/mysql/en/server-system-variables.html

# This will be passed to all mysql clients
# It has been reported that passwords should be enclosed with ticks/quotes
# escpecially if they contain "#" chars...
# Remember to edit /etc/mysql/debian.cnf when changing the socket location.
