// Retrieve the table we just created so we can do some reads and writes
Table table = connection.getTable(TableName.valueOf(TABLE_NAME));

// Write some rows to the table
System.out.println("HelloWorld: Write some greetings to the table");
for (int i = 0; i < GREETINGS.length; i++) {
  // Each row has a unique row key.
  //
  // Note: This example uses sequential numeric IDs for simplicity, but
  // this can result in poor performance in a production application.
  // Since rows are stored in sorted order by key, sequential keys can
  // result in poor distribution of operations across nodes.
  //
  // For more information about how to design a Bigtable schema for the
  // best performance, see the documentation:
  //
  //     https://cloud.google.com/bigtable/docs/schema-design
  String rowKey = "greeting" + i;

  // Put a single row into the table. We could also pass a list of Puts to write a batch.
  Put put = new Put(Bytes.toBytes(rowKey));
  put.addColumn(COLUMN_FAMILY_NAME, COLUMN_NAME, Bytes.toBytes(GREETINGS[i]));
  table.put(put);
}
