I have HBase table with row keys, which consist of text ID and timestamp, like next:
I resolve my problem by using to filters:
- PrefixFilter (I put to this filter first part of row key. In my case - string ID, for example "string_id1.")
- RowFilter (I put there two parametres: first - CompareOp.GREATER_OR_EQUAL, second - all my row key with necessary timestamp, for example "string_id1.1470913345000"
In result I get all cells with row key, which has necessary string_id if first part, and with timestamp more or equal than I put in filter in second part. It is exactly what I want.
val s = new Scan() s.addFamily(family.getBytes) val filterList = new FilterList() filterList.addFilter(new PrefixFilter(Bytes.toBytes(prefixOfRowKey))) filterList.addFilter(new RowFilter(CompareOp.GREATER_OR_EQUAL, new BinaryComparator(valueForBinaryFilter.getBytes()))) s.setFilter(filterList) val scanner = table.getScanner(s)
Thanks to everyone who helped to find a solution.
