HBase row key design for monotonically increasing keys

Question

I\'ve an HBase table where I\'m writing the row keys like:

~1
~2
~3
...
~9
~10

Answer 1

HBase stores rowkeys in lexicographical order, so you can try to use this schema with fixed-length rowrey:

~0001
~0002
~0003
...
~0009
~0010

Keep in mind that you also should use random prefixes to avoid region hot-spotting (when a single region accepts most of the writes, while the other regions are idle).
