redis aof文件解析成命令

waoffle

A Redis AOF file parser. This module parses an AOF structure like this:AOF文件解析器。这个模块解析一个AOF结构是这样的:

*3
$9
PEXPIREAT
$10
myRedisKey
$13
1719298712484
*3
$3
SET
$9
myJSONKey
$24
{"someKey": "someValue"}

... into raw Redis commands, like this:生成命令行如下:

PEXPIREAT myRedisKey 1719298712484
SET myJSONKey {"someKey": "someValue"}

The opposite can also be achieved by using the reverse binary (

rwaoffle

) also provided in this module.相反的也可以通过使用逆向二进制(rwaoffle)也提供了在这个模块。

Installation/Usage

You can install this module via 

npm

:

$ npm install -g waoffle

This installs a global binary 

waoffle

 to which you can use to pipe your syrup data to:

$ cat appendonly.aof | waoffle  # Pipe from other UNIX commands
$ waoffle < appendonly.aof      # or, pipe directly from stdin
$ waoffle appendonly.aof        # or, just specify the filename

Each of the three cases above are equivalent. The generated output will be streamed to stdout, to which you can dump into a file using redirection:上面三种情况下是等价的。生成的输出流发送到stdout,你可以转储到一个文件中使用重定向:

$ waoffle < appendonly.aof > generated_commands.txt

The reverse process—going from sets of operations to AOF format—can be achieved in the same manner by substituting calls to

waoffle

 for 

rwaoffle

.

Importingdata into Redis

This is useful for importing data directly into a running Redis instance. Simply use the 

rwaoffle

 command if you are startingwith a file full of operations. Even though Redis can already read its own AOF file format, this set of tools is even more powerful for filtering your AOF files:这是用于将数据直接导入到运行的复述实例。仅仅使用rwaoffle命令,如果你从一个文件的操作。虽然复述,已经可以读自己的AOF文件格式,这组工具是更强大的过滤AOF文件:

$ waoffle < appendonly.aof | grep SET | rwaoffle    # Only grab `SET` operations

Use this in combination with 

redis-cli --pipe

 for maximum win:

$ cat appendonly.aof | redis-cli --pipe             # Standard Redis import
$ cat commands.txt | rwaoffle | redis-cli --pipe    # Importing a list of commands
$ cat appendonly.aof | waoffle | grep SET \
| rwaoffle | redis-cli --pipe                 # Import only `SET` operations
