◆appendWithRetry()

void Vertica::UDFileOperator::appendWithRetry(const void * buffer, size_t size)

A wrapper around the append(). Attempt to write the specified data to disk. Retry in cases that didn't succeed in writing all data, but that stand a decent chance of succeeding on a retry. Throws on error.
