redis aof檔案解析成命令
waoffle
A Redis AOF file parser. This module parses an AOF structure like this:
AOF檔案解析器。這個模組解析一個AOF結構是這樣的:
*3
$9
PEXPIREAT
$10
myRedisKey
$13
1719298712484
*3
$3
SET
$9
myJSONKey
$24
{"someKey": "someValue"}
... into raw Redis commands, like this:
生成命令列如下:
PEXPIREAT myRedisKey 1719298712484 SET myJSONKey {"someKey": "someValue"}
The opposite can also be achieved by using the reverse binary (rwaoffle
) also provided in this module.
相反的也可以通過使用逆向二進位制(rwaoffle)也提供了在這個模組。
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
$ 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:
上面三種情況下是等價的。生成的輸出流傳送到stdout,你可以轉儲到一個檔案中使用重定向:
$ 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 towaoffle
for rwaoffle
.
Importing data into Redis
This is useful for importing data directly into a running Redis instance. Simply use the rwaoffle
command if you are starting
with 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:
這是用於將資料直接匯入到執行的複述例項。僅僅使用rwaoffle命令,如果你從一個檔案的操作。雖然複述,已經可以讀自己的AOF檔案格式,這組工具是更強大的過濾AOF檔案:
$ 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
