Detailed Description

A single-row write operation to be sent to a Kudu table.

This is the abstract base class from which the particular row operations (KuduInsert, KuduUpdate, etc) are derived. These subclasses are instantiated by KuduTable::NewInsert(), etc.

The row key, as well as the columns to be inserted or updated are set using the embedded KuduPartialRow object accessible via mutable_row().

Typical usage example:

KuduInsert* t = table->NewInsert();
KUDU_CHECK_OK(t->mutable_row()->SetInt32("key", 1234));
KUDU_CHECK_OK(t->mutable_row()->SetStringCopy("foo", "bar"));
session->Apply(t);
