Queue/Worker, Scheduler• Treasure Data: multi-tenant data analytics service
• executes many jobs in shared clusters (queries, imports, ...)
• CORE: queues-workers & schedulers
• Clusters have queues/scheduler... it's not enough • resource limitations for each price plans • priority queues for job types • and many others
PerfectSched
https://github.com/treasure-data/perfectsched
PerfectSched
• Provides periodical/scheduled queries for customers • it's like reliable "cron"
• Highly available distributed scheduler using RDBMS • Written in CRuby
• At-least-once semantics
• PerfectSched enqueues jobs into PerfectQueue

Features
• Priorities for query types
• Resource limits per accounts
• Graceful restarts • Queries must run long time (<= 1d) • New worker code should be loaded, besides
running job with older code
PerfectQueue• Highly available distributed queue using RDBMS
• Enqueue by INSERT INTO • Dequeue/Commit by UPDATE • Using transactions
• Flexible scheduling rather than scalability • Workers does many things
• Plazmadb operations (including importing data) • Building job parameters • Handling results of jobs + kicking other jobs
• Using Amazon RDS (MySQL) internally (+ Workers on EC2)
Builing Jobs/Parameters• Parameters
• for job types, accounts, price plans and clusters • to control performance/parallelism, permissions
and data types • ex: Java properties
• Jobs • to prepare for customers' queries • to make queries safer/faster • ex: Hive Queries (HiveQL, a variety of SQL)

Do you still love Java / SQL ?
PQ written in Ruby• Building jobs/parameters is so complex!
• using data from many configurations (YAML, JSON), internal APIs and RDBMSs
• with many ext syntaxes/rules to tune performance, override configurations for tests, ...
• Ruby empower to write fat/complex worker code
• Testing! • Unit tests using Rspec • System tests (executing real queries/jobs) using
Rspec
For Further improvement about workers
• More performance for more customers and less costs
• More scalability for many other kind jobs
• Better and well-controlled tests (indented here documents!)
"Done is better than Perfect."

?
We'll improve our code step by step, with improvements of ruby and developer community <3
Thanks!
