Use the Fork Luke
Who Cares About ANSI?
2005 OSCON -> 1/(20+)
Custom Advisory Board 2005 (the customers who cared about 5.0 were Embedded)
Do Not Live in the Past
Do not assume everything was bad.
Drop ERP (90s style applications) Drop Data Warehousing Drop Analytic
Focus On Web Applications
MySQL Market is now just entering 16 Core.
Do not play catchup. Leap forward.
Library of Congress is just 26 Terabytes.
The world is 64bit, and there is a lot of RAM. (SSD will be common in two years.)
MicroKernel Move code to the Edge No new features in core To add interfaces you have to remove == amount of code
Multi-Core No new locks Remove old locks Think today: Burn memory (copy on write) Messages scales.
(Dont lose or corrupt data) ACID Compliant Transactional
Innodb is our Default Engine (If Maria or PBXT turn out to be faster, we will switch. Transactional/Performance matter.)
We have no... Stored Procedures Views Triggers No Query Cache
We may though...
SPs through Real Languages
Views are useful, but not when materialized
Triggers no, but maybe Callbacks...
Prepared Statements are out. (no one uses them, they blow up the server)
What we are doing... No required authentication (think http) Round Trip Serialized SQL Make SQL Injection harder
Dump ACL We authenticate in clouds. KISS PAM (Pluggable Authentication Modules) No cost authentication
Authorization is coming...
Do people really sort blobs?
Field Types Less primitives We just now have blob Weakly Typed. 3 byte int? (See Slashdot Comment Problem) Think UUID/IPV4(6)/SERIAL... ENUM tosses an error if a wrong value is inserted.
Интернет является UTF-8. Web UTF - 8 The Web is UTF-8.
UTF-8 Protocol is UTF-8. We store in UTF-8. (default collation is still up for grabs)
Recycle (be lazy, re-use libraries)
Reuse many eyeballs PCRE today (not REGEX) No shipped libraries Maybe ICU? libatomic-ops? Intel Building Blocks? talloc()? glib()? Proto-buffers.
Maintenance Matters (Refactoring is valuable and necessary)
In with the New C99 (types for C++ code) Posix Package-lib STL is in.
TABLE != Table (we are going from C+ to C++)
How big is it? alpha:1,128, rc: 1,009, b: 999,382 Drizzle: 315,560 generated using David A. Wheeler's 'SLOCCount'.
Performance Matters (we all want race cars)
Scale Out Optimizer (OLTP) Execution Engine
Transparency + Edge
LaunchPad Forking is good, no ed patches. Anyone can create an account. Transparency by Launchpad staff.
Buildbot 26 Active platforms. Anyone can sign up a new platform. Completely distributed.
Open Source All internal and external contributors are equal. Captains handle trees, karma gets you in Those who commit are Janitors. Those who only work on their own code are not Captains. Changes are sent to mailing list. Fuzzy ++ system used (negatives are weighed more heavily)
30+ Languages (within 3 months)
Code Drives Decisions
Requirement for Release All Incompatible Changes are completed. (and more require upgrades to version) All tests work. New code additions are fine (think Linux Kernel)
Where is the Money? Support Embedded Non-Recurring Engineering Periphery (no crippleware) Hardware
Innovation Happens Elsewhere
Patrick Galbraith (Principle Engineer/Lycos) Antony Curtis (Google) Transactional Multi-System Integrated Performance Federated X
Transport Eric Day (Architect XO) Asynchronous Multi-protocol Partionalable
