    • 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
  • SCALING TECHNORATI TAGS Technorati Background
    • 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
  • MYISAM VS. INNODB Technorati Background
    • 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 Technorati Background
    • Consider data access methods
    • Measure write and queries rates
    • Partition data by various dimensions
        • Time
        • Key
        • Entity
        • Random key
        • Fixed vs. Variable length columns
  • PARTITIONING Technorati Background
    • 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 : EXAMPLES Technorati Background
    • 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 Background REPLICATION
    • 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
