/**
 * An abstract implementation of {@link BinlogFieldReader} for MySQL.
 *
 * Normally MySQL uses the "Text protocol" to return values; however, when {@code useCursorFetch} is enabled,
 * the driver sets {@code useServerPrepStmts} to {@code true}, which internally causes MysQL to change from
 * the "Text Protocol" to the "Binary Protocol".
