Pipeline¶
transactional pipeline¶
command in the pipeline will be executed once but will block other commands.
example
```py
def trans():
pipe = r.pipeline(True)
pipe.incr('trans:', 2)
time.sleep(.1)
pipe.incr('trans:', -1)
ret = pipe.execute()
print(ret[0])
for i in xrange(5):
threading.Thread(target=trans).start()
time.sleep(.5)
non-transactional pipeline¶
still execute the commands in the pipeline without blocking other commands, for the benefit of increading performance.
