Bruno Dumon updated HBASE-2220:
-------------------------------
Attachment: binary-prefix-comparator-patch.txt
> Add a binary comparator that only compares up to the length of the supplied
> byte array
> --------------------------------------------------------------------------------------
>
> Key: HBASE-2220
> URL: https://issues.apache.org/jira/browse/HBASE-2220
> Project: Hadoop HBase
> Issue Type: New Feature
> Components: filters
> Reporter: Bruno Dumon
> Priority: Minor
> Attachments: binary-prefix-comparator-patch.txt
>
>
> This new comparator is similar to the existing BinaryComparator, but only
> compares up to the length of the supplied byte array.
> The use-case I need this for is secondary indexes. I build a table where the
> row keys have the form {value}{row key}, where {value} is a fixed length byte
> array. On this index table I then would like to perform range scans on just
> the fixed length {value} part. The BinaryPrefixComparator supplied in this
> patch enables exactly this, when used in combination with the RowFilter.
