Take a look at this blog:
http://blog.sematext.com/2012/08/09/consider-using-fuzzyrowfilter-when-in-need-for-secondary-indexes-in-hbase/
From your earlier description, the components of your rowkey have fixed length.
Thus you can consider using fuzzy row filter.

Hi all,
I was wondering if Get is implemented as a private case of scan ?
In HRegion, I see that the get passed is used to construct a Scan object
for the RegionScanner to use.
I was wondering if executing Scan(Get) vs Get from client api should have
any overhead ?
Thanks,
Amit.
Hi all,
I'm trying to measure the size (in bytes) of the data I'm about to load
into HBase.
I'm using bulk load with PutSortReducer.
All bulk load data is loaded into new regions and not added to existing
ones.
In order to count the size of all KeyValues in the Put object I iterate
over the Put's

I'm talking about the store files size and the ratio between store file
size and the byte count as counted in PutSortReducer.

Hello All,
I am writing a filter which skips using hint and includes KeyValue when
conditions are met.
However, when I include A KeyValue, the next call to
filterKeyValue(KeyValue kv) is always the next lexicographical KeyValue.
I would like to skip to the next hint when a Keyvalue is included so

There can be a lot of duplication in what ends up in HFiles but 500MB -
32MB does seem too good to be true.
Could you try writing without GZIP or mess with the hfile reader[1] to see
what your keys look like when at rest in an HFile (and maybe save the
decompressed hfile to compare sizes?)

I have a use case where I need to replicate data from HBase into

accomplishes this.
One uses timestamps to do a timerange scan of the table (since last sync)

Got it. It is because i should use the full path of java cmd( on my site it is
/usr/java/default/bin/java).
If just us java, it is actually point to /usr/bin/java.

to reduce the number of regions, you can increase the
