How about this for a .gitignore? I mixed in Oscar's, CASSANDRA-4899, a
few more general ones which are pretty common, along with a comment
about ignoring db.RowMutation.bin modification, which I've done locally:
--- cut here ---
# C*

src/gen-java/
src/resources/org/apache/cassandra/confi
The first thing I did when I forked the Cassandra repo was add a .gitignore:
--- cut here ---
.classpath
.idea/
.project
build/
src/gen-java/
cassandra.iml
*.pyc
cscope.*
*.swp

This is what I expected as an answer, that effort just fully destroying
any benefits.
All what I can hear is just better not touch stuff which works and find
improvements different way.
Change (algorithms/caching/...) where I agree, and seems like bottleneck
will be FS I/O or network delays.

That's an awfully large reset button you want to press, presumably the
benefits will justify the enormity of effort? What are we talking
here, 10x
Let's ask what we'll lose here.
4 years of work, tons of debugging, loads of instrumentation, for what
gain? Almost nil.

email secur...@apache.org since there isn't a Cassandra specific
security list. This will also help with getting things like CVEs
assigned and making sure balls are not dropped.

You could switch from Jav
That's why we move things off-heap.

One of the core problems what I can see is garbage collection, it blocks
whole server just to clean memory, same stuff with periods of it. On
high load you constantly have to control does the heap close to the
limit specified on start.

Never will say that Erlang will be faster and memory consumption will be
lower than native code. Rest of it totally agree with Brandon, in a few
words I'm talking about serious parallel project on improving Cassandra
basics.

I can agree with you on Java, but the JVM is a different matter. It is
wonderful.

I'm not talking to throw away currently working code. Just port it to
C/C++, and have option to run Java based or "native" binary.

There is a _lot_ of room for performance improvements, both in terms of design

I would start with figuring out exactly how much performance you’re losing

I'm not sure I see a point in this as opposed to developing new features.

The question just as easily be asked, why not rewrite it in Erlang ? Probably
lots of advantages to be gained there, the ability to upgrade on the fly,
native message passing, functional programming paradigm ?
But as Brandon says, you would be throwing away so much work, would it be worth
it
You seem to think something like this is akin to a weekend project. I would
recommend you actually read some of the Cassandra source code and better
understand how it is architected.

Definitely not weekend, I thought about a year of hard development. I
went throw Cassandra code, and can see a lot of work.

Including my own, I count 5 binding +1, one other +1 and no -1. The vote
passes. I'll get the artifacts published asap.
