RedisTimeSeries python client

Last update: Dec 08, 2022

Overview

redistimeseries-py

Deprecation notice

As of redis-py 4.0.0 this library is deprecated. It's features have been merged into redis-py. Please either install it from pypy or the repo.

redistimeseries-py is a package that gives developers easy access to RedisTimeSeries module. The package extends redis-py's interface with RedisTimeSeries's API.

Installation

$ pip install redistimeseries

Development

Create a virtualenv to manage your python dependencies, and ensure it's active. virtualenv -v venv
Install pypoetry to manage your dependencies. pip install poetry
Install dependencies. poetry install

tox runs all tests as its default target. Running tox by itself will run unit tests. Ensure you have a running redis, with the module loaded.

API

The complete documentation of RedisTimeSeries's commands can be found at RedisTimeSeries's website.

Usage example

# Simple example
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)
rts.get('test')
rts.incrby('test',1)
rts.range('test', 0, -1)
rts.range('test', 0, -1, aggregation_type='avg', bucket_size_msec=10)
rts.range('test', 0, -1, aggregation_type='sum', bucket_size_msec=10)
rts.info('test').__dict__

# Example with rules
rts.create('source', retention_msecs=40)
rts.create('sumRule')
rts.create('avgRule')
rts.createrule('source', 'sumRule', 'sum', 20)
rts.createrule('source', 'avgRule', 'avg', 15)
rts.add('source', '*', 1)
rts.add('source', '*', 2)
rts.add('source', '*', 3)
rts.get('sumRule')
rts.get('avgRule')
rts.info('sumRule').__dict__

Further notes on back-filling time series

Since RedisTimeSeries 1.4 we've added the ability to back-fill time series, with different duplicate policies.

The default behavior is to block updates to the same timestamp, and you can control it via the duplicate_policy argument. You can check in detail the duplicate policy documentation.

Bellow you can find an example of the LAST duplicate policy, in which we override duplicate timestamps with the latest value:

from redistimeseries.client import Client
rts = Client()
rts.create('last-upsert', labels={'Time':'Series'}, duplicate_policy='last')
rts.add('last-upsert', 1, 10.0)
rts.add('last-upsert', 1, 5.0)
# should output [(1, 5.0)]
print(rts.range('last-upsert', 0, -1))

Bug in renaming TS key
I run into the following situation (while using Python library)

Calling the following (via Python commands):

TS.CREATE sensor2 LABELS sensor_id 2 TS.ADD sensor2 1548149180000 26 RENAME sensor2 sendor22 TS.MRANGE - + WIDTHLABELS FILTER sensor_id=2

The result of MRANGE is returned with the old key (sensor2) instead of the new one (sensor22)

Response of TS.ADD is incorrectly parsed

I am getting the following error message when trying to add an entry to the time series:

AttributeError: 'long' object has no attribute 'encode'

The command which I am using is:

rts.add(timeseries, ts, v)

I took a quick look and it seems that it's expected that the return value is a string (i.e. OK) but it is a number (i.e. the timestamp itself). Here the full stack trace:

Pubsub integration
What should be the best way to approach even-driven integration with Redis TS.

I.e.

I would like one process to push data to multiple different time series streams (i.e. temperature / pressure with timestamps)

All time-series streams are timestamped together (temperature and pressure are receiving the same timestamp every time)

Other processes should do something when new values are available (i.e. to display it, process it and etc.).

Should this mechanism be addressed separately from TS data processing or is there any better way?

Thanks

Redis 5.0.3 crashed by signal: 11 (Redistimeseries.so with compaction policy set)

Redis frequently crashing when compaction policy is enabled.

loadmodule /opt/redis/redistimeseries.so DUPLICATE_POLICY Last COMPACTION_POLICY sum:300s:90d;count:300s:90d;sum:1800s:180d;count:1800s:180d

When the module is loaded without COMPACTION_POLICY, It is a seamless.

`INFO` seems to be throwing error against `master` branch of `RedisTimeSeries`

Just upgraded RedisTimeSeries to commit e8030d14e7b8e186518b1b551cfa3cde261bf3c3 and am now seeing this when calling client.info() with redistimeseries-py:

Getting error 'redis.exceptions.ResponseError: TSDB: Timestamp cannot be older than the latest timestamp in the time series'

When I am executing add command inside a loop I getting an error here is the traceback with code.

List index out of range in parse_m_get() for emty series.
I use Redis v5.0.5 + RedisTimeSeries module v.1.2.2

Now TS.MGET return array will contain key1, labels1, lastsample1, ..., keyN, labelsN, lastsampleN if series contain some data point. But if series is empty, then TS.MGET in my case return:

1) "analog-key1" 2) 1) 1) "type" 2) "analog" 3) (empty list or set)

The function parse_m_get() can fail as soon as it encounters an empty series. Becauseitem [2] [0] and item [2] [1] will refer to an empty list and will throw an exception "list index out of range".

In version 1.0GA, the RedistimeSeries module when executing TS.MGET would return for an empty series:

"analog-key1" 2) 1) 1) "type" 2) "analog" 3) (integer) 0 4) "0"

For my project, I changed the behavior of the parse_m_getfunction to maintain compatibility with existing code:

def parse_m_get(response): res = [] for item in response: print(item) res.append( { nativestr(item[0]) : [list_to_dict(item[1]), item[2][0] if item[2] else 0, float(item[2][1]) if item[2] else '0'] } ) return res

I can make a pull request if this solution is correct.

Add does not update the key and value for a same timestamp

For my requirement, I was using Redistimeseries module and I have been getting this error saying that

TSDB: Timestamp cannot be older than the latest timestamp in the time series

I want to update the Values in the key for the same timestamp by using the command

TS.ADD

I hope this is an issue as the value should be updated for the same timestamp and not throw an error.

TSDB: wrong toTimestamp when calling range('key', 0, -1)
redistimeseries-py version: 1.4.3 redis-py version: 3.5.3

I'm instantiating a redistimeseries client via rts = Client(redis.Redis(host="XXX", port=6379, password="XXX"))) and subsequently calling a few TS commands.

This command, however, fails. rts.range('key', 0, -1) The following stacktrace is thrown:

return self.parse_response(conn, command_name, **options) File "/usr/local/lib/python3.6/dist-packages/redis/client.py", line 915, in parse_response response = connection.read_response() File "/usr/local/lib/python3.6/dist-packages/redis/connection.py", line 756, in read_response raise response redis.exceptions.ResponseError: TSDB: wrong toTimestamp

Not sure if this can be addressed in this library as it seems like it's an issue with redis-py? The equivalent range command executed directly in redis-cli performs as intended.

Support `DUPLICATE_POLICY` on `ts.add`

TS.ADD supports setting DUPLICATE_POLICY as well as/independently from ON_DUPLICATE. The two have separate behaviors -- DUPLICATE_POLICY sets the default for the key of TS.ADD does an implicit create, and ON_DUPLICATE overrides the existing default for the key on a particular add. It would be nice to support both.

Relevant issue from RedisTimeSeries to add documentation for this support: https://github.com/RedisTimeSeries/RedisTimeSeries/issues/889

how to store a dictionary? and retrieve using range command

Hi,

I am using Redis for the first time so I don't have a lot of understanding of how this works in python. I have a dictionary with multiple keys along with a time key. I need to save the data in Redis and then retrieve multiple data points using the range function.

data = {'timestamp': 124567889, 'datetime' :9/27/2018 9:04, 'sensor1': 34, 'sensor2': 56, 'sensor3': 90,'sensor4' : 12}

Issue 1:

how can I save this using the Redis time series module?

currently i am creating seperate time series for every sensor :

rts.create(sensor1, labels = {'time':'series'},duplicate_policy='last') rts.create(sensor2, labels = {'time':'series'},duplicate_policy='last')

and then adding individual values to each time series : rts.add(sensor1,unixtime,34) rts.add(sensor2,unixtime,56)

I will have more than 100 different values in the next stage and my current method takes some time to save the data. so is there an easier way where I can save all values together without having to create and save each value individually?

Issue 2:

Also, I am trying to retrieve the data using the range function in the following manner:

rts.range('datetime',start_time,end_time)

but when the date is returned it just says '9.0' instead of complete date '9/272018 9:04'.

any help would be much appreciated.

Thank You.
