About the use of LSM Trees

[Anurag Awasthi <an...@gmail.com>]

Hi,

I was reading about the LSM Trees in HBase and just had a couple of doubts,
(please correct me if I am wrong) -

1. The trees use BTree indexing model for C1, C2 trees on Disk. So is this
the same Data Block Index (below File info block) and Metadata Block Index
that are a part of an HFile?
2. What is the level of 'k' (as a part of multi level LSM trees C0, C1,
C2...., Ck) that HBase is currently using.

Thanks,
Regards,
