Data can be inserted into HBase for a single row or as a batch representing multiple
rows using the following method of the
HTable
class:
void put(List<Put> puts)
A list of
Put
instances can be created, as follows:
List<Put> puts = new ArrayList<Put>();
Put put1 = new Put(Bytes.toBytes("row-1"));
put1.add(Bytes.toBytes("cf1"), Bytes.toBytes("greet"),Bytes.
toBytes("Hello"));
puts.add(put1);
