Hi,
I'm currently playing with hbase. The design of the rowkey seems to be
critical.
The rowkey for a certain database table of mine is:
timestamp+ipaddress
It looks something like this when performing a scan on the table in the shell:
hbase(main):012:0> scan 'ToyDataTable'
ROW COLUMN+CELL
1357020000000+192.168.178.9 column=CF:SampleCol,
timestamp=1361288601717, value=Entry_1 = 2013-01-01 07:00:00
Since I got several rows for different timestamps I'd like to tell a
scan to just a region of the table for example from 2013-01-07 to
2013-01-09. Previously I only had a timestamp as the rowkey and I
could restrict the rowkey like that:
SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
Date startDate = formatter.parse("2013-01-07 07:00:00");
Date endDate = formatter.parse("2013-01-10 07:00:00");
HTableInterface toyDataTable =
pool.getTable("ToyDataTable");
Scan scan = new Scan( Bytes.toBytes(
startDate.getTime() ),
Bytes.toBytes( endDate.getTime() ) );
But this no longer works with my new design.
Is there a way to tell the scan object to filter the rows with respect
to the timestamp, or do I have to use a filter object?
