Retrieving timestamp from hbase row

Using Hbase API (Get/Put) or HBQL API, is it possible to retrieve timestamp of a particular column?

Solution

  • Assuming your client is configured and you have a table setup. Doing a get returns a Result

    Get get = new Get(Bytes.toBytes("row_key"));
Result result_foo = table.get(get);

    A Result is backed by a KeyValue. KeyValues contain the timestamps. You can get either a list of KeyValues with list() or get an array with raw(). A KeyValue has a get timestamp method.

    result_foo.raw()[0].getTimestamp()
