HBase: how to filter by “key not start with”

Question

using PrefixFilter("word") it is possible to filter all keys which start with "word". I am trying to get the opposite, all key which not start with "word".

Is it a filter which ,match to my requirement? If I will need to create a Filter from my own, will it work? ( I am not sure if the HBase scanner supports new filters)

Answer 1

I manage to achieve the same behavior using RowFilter and RegexStringComparator classes ie:

RowFilter prefixFilter = new RowFilter(CompareFilter.CompareOp.NOT_EQUAL,
 new RegexStringComparator("word"+"[\\S]+"));
