--lossy-conversions, -l

允许在转换为较小类型时截断属性数据。Allow attribute data to be truncated when converted to a smaller type.

--ndb-connectstring

设置用于连接到 ndb_mgmd 的连接字符串。语法：[nodeid=id;][host=]hostname[:port]。覆盖 NDB_CONNECTSTRING 和 my.cnf 中的条目。Set connection string for connecting to ndb_mgmd. Syntax: [nodeid=id;][host=]hostname[:port]. Overrides entries in NDB_CONNECTSTRING and my.cnf.

--ndb-mgm-tls

设置连接到管理服务器所需的 TLS 支持级别；可以是 relaxed 或 strict。relaxed（默认）表示尝试建立 TLS 连接，但不要求成功；strict表示连接必须使用 TLS。Sets the level of TLS support required to connect to the management server; one of relaxed or strict. relaxed (the default) means that a TLS connection is attempted, but success is not required; strict means that TLS is required to connect.

--ndb-mgmd-host

与 --ndb-connectstring 相同。Same as --ndb-connectstring.

--ndb-nodeid

为此节点设置节点 ID，覆盖由 --ndb-connectstring 设置的任何 ID。Set node ID for this node, overriding any ID set by --ndb-connectstring.

--ndb-optimized-node-selection

启用事务节点选择的优化。默认启用；使用 --skip-ndb-optimized-node-selection 来禁用。Enable optimizations for selection of nodes for transactions. Enabled by default; use --skip-ndb-optimized-node-selection to disable.

--ndb-tls-search-path

指定用于搜索 CA 文件的目录列表。在 Unix 平台上，目录名称用冒号 (:) 分隔；在 Windows 系统上，使用分号 (;) 作为分隔符。目录引用可以是相对路径或绝对路径；它可以包含一个或多个环境变量，每个变量以美元符号 ($) 开头，并在使用前进行展开。Specify a list of directories to search for a CA file. On Unix platforms, the directory names are separated by colons (:); on Windows systems, the semicolon character (;) is used as the separator. A directory reference may be relative or absolute; it may contain one or more environment variables, each denoted by a prefixed dollar sign ($), and expanded prior to use.

搜索从最左边的命名目录开始，按从左到右的顺序进行，直到找到文件。空字符串表示空搜索路径，这会导致所有搜索失败。由单个点 (.) 组成的字符串表示搜索路径仅限于当前工作目录。Searching begins with the leftmost named directory and proceeds from left to right until a file is found. An empty string denotes an empty search path, which causes all searches to fail. A string consisting of a single dot (.) indicates that the search path limited to the current working directory.

如果未提供搜索路径，则使用编译时的默认值。此值取决于所使用的平台：在 Windows 上，它是 \ndb-tls；在其他平台（包括 Linux）上，它是 $HOME/ndb-tls。可以通过使用 -DWITH_NDB_TLS_SEARCH_PATH 编译 NDB Cluster 来覆盖该值。If no search path is supplied, the compiled-in default value is used. This value depends on the platform used: On Windows, this is \ndb-tls; on other platforms (including Linux), it is $HOME/ndb-tls. This can be overridden by compiling NDB Cluster using -DWITH_NDB_TLS_SEARCH_PATH.

--no-defaults

除了登录文件之外，不从任何配置文件读取默认选项。Do not read default options from any option file other than login file.

--print-defaults

打印程序参数列表然后退出。Print program argument list and exit.

--promote-attributes, -A

允许将属性数据转换为更大的类型。Allow attribute data to be converted to a larger type.

--staging-tries=x[,y[,z]]

指定临时错误时的重试次数。格式为 x[,y[,z]]，其中 x=最大重试次数（0=无限制），y=最小延迟（毫秒），z=最大延迟（毫秒）。Specify tries on temporary errors. Format is x[,y[,z]] where x=max tries (0=no limit), y=min delay (ms), z=max delay (ms).

--usage

显示帮助文本并退出；相当于 --help。Display help text and exit; same as --help.

--verbose

启用详细信息消息。Enable verbose messages.

--version

显示版本信息并退出。Display version information and exit.
