Ah, I meant quite a few of the mirror links keep showing up as links to
gossip sites and whatnot.

I was playing around with secondary indexes in 0.7 RC2 through the command
line, and I can't seem to get them work with a TimeUUIDType Column Family.
For Instance:
create column family TestSecondaryIndexes with comparator = TimeUUIDType
... and column_metadata=[{column_name: uuid_nondexed, valida

Is it possible to perform paginated queries using Random Partitioner in 0.7
with Super Column Families whose Super Columns are UUID's? I don't believe
it is, based on this article:

I have a cluster of 3 0.7 beta 2 nodes (built today from the latest trunk)
running on Large, EBS-backed, x64 EC2 instances; RF=3. I attempted to write
somewhere near 500,000 records every 15 minutes from a total of 5 different
computers (using Pelops and multi-threading). Though my network blew
t example for super columns? I am trying to count the
number of occurrences of "DEADBEEFFEED", much like "word1" in the column
example.

I understand adding column family configuration fields using thrift in
Pelops for system_add_column_family, and even renaming column families, but
what about modifying the actual column family configuration values,
e.g. read_repair_chance: 1.0 to read_repair_chance: .5 (as a poor example)?

Question regarding schema set-up and modification: I just set up the newest
nightly build of 0.7, imported our .yaml file after starting Cassandra, and
everything is honky-dorey. We're not sure if Pelops is capable of modifying
shema definitions, but it doesn't appear any changes we make to the .
I actually need a similar query; can someone update the wiki on adding a
secondary index in 0.7?

I now have 2 running nodes : one running .6.3, and one running .7 beta 1.
No Keyspace is recognized (aside from system) on the .7 beta 1 node; I saw
