How to set start and end row key HBASE

Question

If i have row keys like

a_c
b_c
j_f
f_d
d_c

I should get all the rows matching _c. How to set start and stop row key here . I am trying to get the scan result out of start and stop row key and not with rowfilter or other filter types.

Answer 1

You can write your own filter function if you don't want to use RowFilter . But I suggest you to use PrefixFilter if you can't write your own filter function and don't want to use RowFilter

Example for Java:

byte[] prefixF= Bytes.toBytes("_c");
Scan scan = new Scan(prefixF));
PrefixFilter prefixFilter = new PrefixFilter(prefixF);
scan.addFilter(prefixFilter);
ResultScanner resultScanner = table.getScanner(scan);

Above code is equal to hbase> scan 'YourTablename', { FILTER => "PrefixFilter('_c')"}

Answer 2

You can use Hbase STARTROW and ENDROW filter. It basically scans data between the rowkey range (ENDROW excluded).

 scan 'table_name', {STARTROW=>"<start_row_key>", ENDROW=>"<end_row_key>"}
