Enis Soztutar commented on HBASE-1197:
--------------------------------------
This ties into blob store discussions which would enable a lot of more
interesting use cases for hbase. However, it is an architectural level work
that can sit on top of hbase as well, like what Microsoft did in
http://sigops.org/sosp/sosp11/current/2011-Cascais/printable/11-calder.pdf
Even if we are able to store large cells in hfiles, the write amplification
from compactions would be a big problem. We would like to use the block storage
in hdfs directly to store large objects. Andrew, you had a coprocessor + custom
compactions based solution for this, no?
> IPC of large cells should transfer in chunks not via naive full copy

> Several instances of OOME when trying to serve up large cells to clients have
> been observed. IPC should send large cell content in chunks instead of as one
> large naive copy.
