everyone just has a root user with all privs, why carry the baggage of the

A micro-kernel that we then extend to add what we need (all additions come

through interfaces that can be compiled/loaded in as needed).

* What is left to be cut out?

Bit type... we need a longer list.

Please ask on the mailing list or on IRC.
64
Most certainly. There is plenty to do from refactoring code, design of intereface,
65
to documentation, etc... The best way to get involved it to join the mailing

If you wish to suggest a refactoring project or an interface please email
70
the mailing list and keep an open mind. Do not expect anyone will work on
71
your idea though, you may influence someone to do that, but more then likely
72
you will need to rollup your sleaves and write some code. For very simple
73
bits you are welcome to ask others on #drizzle on Freenode, but please be
74
aware that you may be asked to email the mailing list.
76
Showing up with a big block of code is probably the worst way of getting
77
your work accepted. This is unlikely to work.
79
Right now we use a simple captain system for commits. Anyone can send in a
80
proprosal for merge via launchpad but your changes may be flowed first
81
through someone who has been around long enough to understand code
82
requirements to review your code. This system is based entirely on trust,
83
and individuals who have shown that they can provide three good patches gain
84
credibility. Starting small is fine, patches that are just comments or are
85
event two or three line cleanups are welcome and encouraged. I would really
86
recommend anyone who wants to work on something start with something of this
87
size. Patches like these are valuable and they teach you how to work with
90
The general rule is no new code in the core of the server, and any changes
91
to interfaces need to be code line neutral. AKA if you want to add an
92
interface you need to be able to remove at least the number of lines of code
93
you added. This is a rule of thumb, and does not apply to code cleanup.
95
It should be pointed out that we are more focused on code style,
96
performance, and over all maintenance then we are features.

* What is the coding style?

Please god no, we live in the age of the Internet :)

* What is the target?
116
Deliver a microkernel that we can use to build a database that meets the
117
needs of a web/cloud infrastructure. To this end we are exploring http
118
interfaces, sharding enhancements, etc... do not expect an Oracle, MySQL,
119
Postgres, or DB2. There is no GA date at the moment.
121
We are focusing on multi-core architecture. This is not designed to run on a
122
wrist watch (hint, go use SQLite). We support both 32bit and 64bit but the
123
class of machine we are targetting is 64bit. We are making design decisions
124
which assume very large amounts of RAM will be made available to the DB.
126
* Can I run a website with this?
128
No. We are stil making incompatible changes, and I certainly do not believe
129
the code is production quality. Right now we are defaulting many configure
130
operations to generate debugging code for us so our binaries are not
131
optimum, so do not got out and benchmark this and expect it to be one way or
132
the other. We are currently only doing benchmarks where it makes sense for
133
us to determine where bottlenecks are.
