/**
 *
 * JDBC ResultSet implementation of Phoenix.
 * Currently only the following data types are supported:
 * - String
 * - Date
 * - Time
 * - Timestamp
 * - BigDecimal
 * - Double
 * - Float
 * - Int
 * - Short
 * - Long
 * - Binary
 * - Array - 1D
 * None of the update or delete methods are supported.
 * The ResultSet only supports the following options:
