Hi,
We are migrating from a 0.8.8 ring to a 1.1.2 ring and we are noticing

Is there a wildcard for the COLUMNFAMILY field in `access.properties`?
I'd like to split read-write and read-only access between my backend and
frontend users, respectively, however the full list of CFs is not known
a priori.
I'm using 0.7.4.

Sankalp,
Parallel sstableloader streaming would definitely be valuable.
However, this ring is currently using vnodes and I was surprised to see
to share it. I guess this kind of comment on
configuration is usable by the entire community.

simply commented out the line which kills
tablesnap if the file is not found, it fixes the issue we were having but I
would appreciate if some one has any insights on any ill effects this might
have on backup or restoration process.

what it is time-consuming the data streaming from (or to) other node, right?

What is the proper way to perform a column slice using CQL with 1.2?
I have a CF with a primary key X and 3 composite columns (A, B, C). I'd

So if I switch to:
SELECT * FROM CF WHERE key='X' AND column1=1 AND column2=3 AND column34
That doesn't include rows where column1=2, which breaks the original

One thing to add, if we do a rolling restart of the ring the timeouts
disappear entirely for several hours and performance returns to normal.
It's as if something is leaking over time, but we haven't seen any
noticeable change in heap.

more information that may help.
We are pretty much at the point of sprinkling debug around the code to
track down what could be blocking.
