CCIndex for cassandra
Hello HBase,
I am a cassandra user and i want to implement the CCIndex scheme in
cassandra. Can anyone help me to understand the CCIndex code ? I want to
modify the CCIndex code so that it will use the Cassandra's APIs.

You are mailing a HBase mailing list. Since your only interest seems centered around Cassandra, you should ask your question on a mailing list of theirs.

Re: CCIndex for cassandra
Posted by bjbhutkar <bh...@gmail.com>.
The thing I am interested in is in correspondence with cassandra. Cassandra
currently supports multidimensional range queries with a limitation that at
least one of the dimensions supplied in the query must be of equality
operation
example : "Select * from table where Weight > 65 AND Height < 6 AND Country
= India" . This is supported in cassandra.
But "Select * from table where Weight > 65 AND Height < 6" this query is
not possible with current cassandra version. To mitigate this problem I
thought of implementing the CCIndex in cassandra as the paper claims to
provide such functionality.
I searched around and found the code for CCIndex on github . I was
wondering whether this code can be modified so that it uses Cassandra's
APIs. Furthermore , If anybody's having any suggestions for implementing
such functionality then please let me know . Is such functionality provided
in HBase or not ? If yes , then how the algorithm works for querying the
data where all the dimensions in a query are either "Less Than (<) "or "Greater
Than (>)" ?

Re: CCIndex
Posted by Andrew Purtell <an...@gmail.com>.
CCIndex was work done by a grad student at the Chinese Academy of Sciences. He/they talked with us years ago about getting this in. The advice (this was just before 0.92 was branched) was to redo it as a coprocessor. I specifically remember wondering about how to hook IOEs from missed HFile reads - for when a read of an index with reduced replication hits a missing block and an index rebuild must be triggered. That would have been an interesting use case for the CP framework. However I think everyone moved on without this happening.

Re: CCIndex for cassandra

Hi Bhalchandra,
This is a 3 years old PDF, and still, I'm not able to find any trace
of that in HBase anywhere. Sorry. Seems that it was based on HBase
0.20.1. We are now at 0.94.5...
Maybe it's a vendor extension which has not been published/released?

Re: CCIndex for cassandra

Hi,
What do you mean by CCIndex?
The only thing I found about that is https://github.com/Jia-Liu/CCIndex and
it has not been updated for 2 years now.
Also found that wich is more recent:
https://github.com/ICT-Ope/CCIndex_HBase_0.90.0
You can also read this thread:
http://www.mail-archive.com/dev@hbase.apache.org/msg06553.html
Looking at the code I was not able to fine any class name close to that
neither I found anything into the HBase classes. (Searched for *CC*Index*)
All of that to say, I'm not sure this is integrated in HBase today.
But I might be wrong. Do you have any reference about what you are looking
for?
