redis-pipe：像Unix Pipes一樣對待 Redis Lists

redis-pipe可以讓你處理Redis的列表，好像他們是Unix的管道。它基本上是利用LPUSH和LPOP連接 stdin 與 stdout。

How it works

Configuration

Set theREDIS_HOSTandREDIS_PORTenvironment variables for easy configuration or pass--hostand--portarguments.

Writing from stdin to Redis List

Pipe in value toredis-pipeand it willLPUSHthem to the Redis List.

echo "hi there" | ./redis-pipe greetings

Reading from Redis List to stdout

If you callredis-pipewith a tty attached it willLPOPall values from the Redis List and write them to stdout.

./redis-pipe greetings

You can also limit the amount of values popped from the list.

./redis-pipe --count 100 greetings

Support for blocking mode withBLPOPis not supported yet.

Examples

Centralized Logging

In this sample we pipe the syslog to a Redis List calledlogs.

tail -f /var/log/syslog | ./redis-pipe logs

You can now easily collect all the syslogs of your machines on a single server.

./redis-pipe logs > logs.txt

Very basic job queue

Create jobs and store them.

cat jobs.txt | ./redis-pipe jobs

Process jobs on several workers and store the results.

./redis-pipe --count 10 jobs | python do-work.py | ./redis-pipe results

Collect the results.

./redis-pipe results > results.txt
