is a nice integration with flume and kite.
High availability didnet matter for us. 10 secs down is fine for our use
cases.HBase started to support eventually consistent reads.

What do you think about that? Is there anyone who has 2 nodes cluster?

It will be deleted after a compaction.

Have a look to index_interval.

Hi Alain,
I solved the same issue by implementing a client that manages time range
partitions. Each time range partition is a CF.

store is relatively small.
Why didnt you partition your data according to time instead of using your
own compactor?

You will suffer from long compactions if you are planning to get rid of
from old records by TTL.

Between 500GB - 1TB is recommended.
But it depends also your hardware, traffic characteristics and
requirements. Can you give some details on that?

Hi All,
Can anyone explain the compression ratio?
Is it the "compressed data / original" or "original/ compressed" ? Or
something else.
thanks a lot.

Do I need to enable anything to leverage from 1.2? Do you have any other
advice?
What should be the path to investigate this?
Thanks in advance!

Thank you very much for the fast answer.
Does playORM use different column families for each partition in Cassandra?

Hi Alicia ,
Cassandra input format creates mappers as many as vnodes. It is a known
issue. You need to lower the number of vnodes :(
I have a simple solution for that and ready to write a patch. Should I
create a ticket about that? I don't know the procedure about that.

Hi,
Could you provide some other details about your schema design and queries?
It is very hard to tell anything.

eries because in the typical range query you need to set start and end
token. But in the virtual nodes I realized that tokens are not continuous.

Since all hosts are seem to be down, Hector will not do retry. There should
be at least one node up in a cluster. Make sure that you have a proper
connection from your webapps to your cluster.

records after a
down node comes back. So I assumed that transferring expired records will
not cause any problem.
Do you have any idea? Thank you!
