Looking at the docs, I can't conclusively answer this question:
Suppose I make this CQL query with consistency factor 1 and read-repair
100%:
select 'a'..'z' from cf where key = 'xyz' limit 5;
Suppose the node I connect to has the key and responds with (improvised
syntax):
['a'->0, 'c'->2, 'e'->4,
here's what i ended up, this seems to work for me.
@Test
public void readAndWriteSettingTTL() throws Exception {
int ttl = 2;
String columnFamily = "Quote";
Set symbols = new HashSet(){{
add("appl");
Thanks, folks.
I think I must have read compaction, thought cleanup, and gotten muddled
from there.

Your understanding of nodetool cleanup is not correct. cleanup is used only
after cluster balancing like adding or removing nodes. It removes data that
does not belong on the node anymore (in older versions it removed hints as
well)

I don't think so. That code hasn't changed in a long time. Is it reproducible?

You wouldn't query for all the keys that have a column name x exactly.
Instead what you would do is for sector x grab your list of symbols S.
Then you would get the last column for each of those symbols (which you do
in different ways depending on the API), and then test if that date is
within yo
with the quote CF below how would one query for all keys that have a
column name value that have a timeuuid of later than x minutes? i need
to be able to find all symbols that have not been fetch in x minutes by
sector. i know i get list of symbol by sector from my sector CF.

I believe you are mis-understanding what cleanup does. Cleanup is used
to remove data from a node that the node no longer owns. For example
when you move a node in the ring, it changes responsibility and gets
new data, but does not automatically delete the data it used to be
responsible for but no
Personally I would create a separate column family for each basic area.
For example
To organize my sectors and symbols I would create a column family where the
key is the sector name and the column names are the symbols for that
sector, i.e.:
sector : {
key: sector name
Column names: sym
hey all!
i'm started my first project using cassandra and some data model
questions. i'm working on an app that fetches stock market data. i
need to keep track of when i fetch a set of data for any given stock in
any sector; here's what i think my model should look like;

As indicated in a preceding mail (http://goo.gl/R1r1V), the release of 1.0.4
unfortunately shipped with two important regressions. The Cassandra team is
pleased to announce the release of Apache Cassandra version 1.0.5 that comes
to fix those two issues[1], but is identical to 1.0.4 otherwise.

Nodetool repair also don't start on all nodes, log is reporting:
INFO 15:57:51,070 Starting repair command #2, repairing 0 ranges.
INFO 15:57:51,070 Repair command #2 completed successfully
Regular read repairs are working as reads and writes.

In my understanding Cleanup is meant to help clear out data that has been
removed. If you have an environment where data is only ever added (the
case for the production system I'm working with), is there a point to
automating cleanup? I understand that if we were to ever purge a segment
of data
Cassandra version 0.8.7, after adding new nodes we can't run cleanup on any
node.
Log reports: "Cleanup cannot run before a node has joined the ring"
New nodes has joined (one by one), all nodes up & running, reading, writing...
Not sending/receiving any streams on any node for more than 12 hour
