We house about 10 TB of core data in MySQL over about

20 machines

With replication, we add 100TB and 200 machines more

We grow at about 1TB per day in total

We use a service oriented architecture to separate

physical and logical access

We use commodity hardware and Open Source software

Technorati Background

Technorati BackgroundSCALING TECHNORATI TAGS

Partition data by Entity (tags and posttags)

Blend of InnoDB and MyISAM based on use

over time

Replicate to distribute query load and async

calculations

Technorati BackgroundMYISAM VS. INNODB

Different storage engines serve very different

purposes.

InnoDB is the right choice for Master-class DB’s

where data integrity is key and write loads are

high

MyISAM is the right choice for GROUP BY

queries and for read-mostly applications


PARTITIONING

Consider data access methods

Measure write and queries rates Partition data by various dimensions

TimeKeyEntityRandom keyFixed vs. Variable length columns


At Technorati, we use all of these and some in combination

Cosmos DB for the entire Blogosphere

ID based using mod to allocate to shard

Entity based to organize commonly queried lookup tables in

one location

Entity based but ID range partitioned

Time based for reporting data (hourly or daily)

PARTITIONING

Technorati BackgroundPARTITIONING : EXAMPLES

Main data set is sharded by Blog ID with a

central sequence generation and map

Collation is performed in the application tier

Blog post data is split between fixed length and

variable length columns

Technorati BackgroundREPLICATION

MySQL replication is an essential tool to

distribute query load and provide for

redundancy.

Master -> Master -> Slave can be used to

distribute common lookup tables

mysqldump is also a good way to bootstrap a

new slave
