Karthick Sankarachary commented on HBASE-3732:
----------------------------------------------
Does it make sense to perform the compression at the IPC layer, specifically in
the {{HBaseClient}} and {{HBaseServer}} classes? Currently, then both read
(write) headers and data through a {{DataInputStream}} ({{DataOutputStream}}).
What if we wrap those streams such that it compresses the bytes flowing through
it, based on the yet-to-be-determined config option? As a matter of fact, I was
working on something along these lines last year, but didn't follow through on
it. Luckily, I still have the compression-based streams that I wrote, and I'm
attaching those here just to get your thoughts. If this approach truly makes
sense, then I can try to put together a working patch.

> Key: HBASE-3732
> URL: https://issues.apache.org/jira/browse/HBASE-3732
> Project: HBase
> Issue Type: New Feature
> Reporter: Jean-Daniel Cryans
> Fix For: 0.92.0

> Attachments: compressed_streams.jar

>
> We have a case here where we have to store very fat cells (arrays of
> integers) which can amount into the hundreds of KBs that we need to read
> often, concurrently, and possibly keep in cache. Compressing the values on
> the client using java.util.zip's Deflater before sending them to HBase proved
> to be in our case almost an order of magnitude faster.
> There reasons are evident: less data sent to hbase, memstore contains
> compressed data, block cache contains compressed data too, etc.
> I was thinking that it might be something useful to add to a family schema,
> so that Put/Result do the conversion for you. The actual compression algo
> should also be configurable.
