Pipelining get

[elan-izidane]

Hi,
I am trying to run something like:

pipeline = time_series_client.pipeline(transaction=False)
for key in my_list_of_keys:
    pipeline.get(key)
my_data = pipeline.execute()

This does not work, I could not find tests for get with pipelines. Adding works great though.
My guess is that it is doing a "GET" and not a "TS.GET" (have not tested this).

from redistimeseries.client import Client
rts = Client()
rts.create('test', labels={'Time':'Series'})
rts.add('test', 1, 1.12)
rts.add('test', 2, 1.12)

pipeline = rts.pipeline(transaction=False)
pipeline.get('test')
print(pipeline.execute() )

result [(2, 1.12)]

Hi,
Thanks vm for your response.

Here is my code:

from redistimeseries.client import Client as RedisTS
client_kwargs = {"host": hostname, "port": port, "decode_responses": True}
rts = RedisTS(**client_kwargs)
rts.create('test', labels={'Time': 'Series'})
rts.add('test', 1, 1.12)
rts.add('test', 2, 1.12)

print(rts.get('test'))

pipeline = rts.pipeline(transaction=False)
pipeline.get('test')
print(pipeline.execute())

The first print does print (2, 1.12), the second raises:

Exception has occurred: ResponseError
Command # 1 (GET test) of pipeline caused error: WRONGTYPE Operation against a key holding the wrong kind of value
  File "/usr/local/pip-global/redis/connection.py", line 756, in read_response
    raise response
  File "/usr/local/pip-global/redis/client.py", line 915, in parse_response
    response = connection.read_response()
  File "/usr/local/pip-global/redis/client.py", line 3977, in parse_response
    result = Redis.parse_response(
  File "/usr/local/pip-global/redis/client.py", line 3961, in _execute_pipeline
    self.raise_first_error(commands, response)
  File "/usr/local/pip-global/redis/client.py", line 3968, in raise_first_error
    raise r
  File "/usr/local/pip-global/redis/client.py", line 3961, in _execute_pipeline
    self.raise_first_error(commands, response)

    return execute(conn, stack, raise_on_error)
  File "/workspaces/app/command/play_with_redis.py", line 31, in <module>
    print(pipeline.execute())

I am running redislabs/redismod:latest and this client.

$ pip3 freeze | grep redis
hiredis==1.1.0
redis==3.5.3
redistimeseries==1.4.3

output of module list on the cli:
