He there, I'm still getting odd behavior with get_range_slices. I've
created a JUNIT test that illustrates the case.
Could someone take a look and either let me know where my
understanding is wrong or is this is a real issue?
I added the following to ColumnFamilyStoreTest.java

Hi
I have looking at the bootstrap source and seem to understand it for the
most part. This is what I do not follow:
(1) New node joins and doesn't advertise its token.
(2) Requests nodes to send it data. The nodes that need to send it data

1. I wrote the list a while back about less-than-great performance when
reading thousands of columns even on cache hits. Last night, I decided to
try to get to the bottom of why.
I tested this by setting the row cache capacity on a TimeUUIDType-sorted CF
to 10, filling up a single row wi
Not sure why the first paragraph turned in to a numbered bullet...

Hello,
1) Can you provide a solution or a sample for searching (Column and
SuperColumn) (Fulltext).
What is the Way to realize this? Hadoop/MapReduce? See you a posibility to
build/use a index for columns?
Why this: In a given Data-Model we "must" use UUIDs as Key and have actually no
chance t

This data structure recognizes to the way based on the idea of

though Bloom filter is adopted for the data structure in Cassandra as
shape to allow no limited adjustment.
In a word, there is a problem of generating the false positive rate.
Moreover, data is delet
Just an update on this. I wrote a patch which attempts to solve this problem
by keeping an index of columns that are marked for deletion to avoid having
to iterate over the whole column set and call columns_.get() over and over
again.
My patch works, and the time spent in removeDeleted() is now cl
Got a ~50% improvement by making UUID comparison less heavy-weight.
