Hi - Couple of questions -
1) What is the ratio of the sstable file size to bloom filter size ? If i have
a sstable of 1 GB, what is the approximate bloom filter size ? Assuming
0.000744 default val configured.
2) The bloom filters are stored in RAM but not in help from 1.2 onwards ?
3)
I'd like to upgrade from 1.1.6 to 1.2.1, one big feature in 1.2 is that it
can have multiple tokens in one node. but there is only one token in 1.1.6.
how can I upgrade to 1.2.1 then breaking the token to take advantage of
this feature? I went through this doc but it does not say how to change
Can you run the select in cqlsh and enabling tracing (see the cqlsh online
help).
If you can replicate it then place raise a ticket on
https://issues.apache.org/jira/browse/CASSANDRA and update email thread.
Thanks

Hi - The index files created for the SSTables. Do they contain a sampling or
the complete index ? Cassandra on startup loads these files based on the
sampling rate in Cassandra.yaml ..right ?
What version are you looking at ?
I *think* it should be testing against the start of the next slice. It should
not have to test any more as per the comments at the top of IndexedSliceReader,
the slices are ordered. (I'm not sure if slices can overlap though)
The best way I can think to
Any alternative to achieve this?
Nothing server side.
i.e. you cannot do Update foo set bar='baz' where timestamp new_timestamp
You can monkey around with the timestamps a little though.
Cassandra will return you the column value with the highest (internal
cassandra) time stamp. Now days
If you are using Murmur3 partitioner and do not wish to partake in vnodes you
can still calculate inital_tokens.
There is a guide here

I've got a table that has a column called date. I created an index on
the column date with the following command:
CREATE INDEX date_key ON ola (date);
Now, I can perform the following command:
select * from ola where date = '2013-01-01' limit 10;
The results are correctly displayed.
But the

Right, at that point either, cassandra-cli or cqlsh will not see any
endpoint. Only after you drop the keyspace and re-create it with
cassandra-cli will properly work.
