QUESTION
I was trying to insert 1M entries in redis timeseries DB (on my local machine). For this, I was using add(sourceKey, timestamp, value) method of RedisTimeSeries on every entry.
Wanted to know if there's a better way to do this and if bulk load is possible in redis timeseries.
Couldn't find a method for bulk loading of data in this doc: https://oss.redis.com/redistimeseries/commands/#tsadd
Thanks
...ANSWER
Answered 2021-Oct-27 at 15:51Currently, the fastest way is to combine pipelining and the TS.MADD
command
QUESTION
I'm confused trying to figure out whether RedisTimeSeries is free or not. I saw it is open source, but i also saw something there is rate limit. So i am very confused. Could I setup RedisTimeSeries on my own cluster without paying or not?
...ANSWER
Answered 2021-Sep-02 at 09:29RedisTimeSeries is source available and licenced under Redis Source Available License
(RSAL). This license is permissive if your product is not a "database product". The definition of "database product" is within the license. There is no such thing as a "rate limit" for RedisTimeSeries, at least not with regards to the license.

QUESTION
I am currently trying to do a simple implementation for stock price candle sticks. Let's say we have a stock called XYZ. This stock receives a stream of prices (in no particular frequency), which (for example) looks like: XYZ: [10.2, 10.7, 12, 11 ....].
The objective is to record some metrics for every minute that passes to reflect the state of that stock. A candle stick has metrics like Closing price (last known price within a minute), High Price (maximum price within a minute)...etc.
One way I thought I can implement this is by using Redis TimeSeries. I considered this solution because I can create rules on the stream of prices, and every 60 seconds it would flush some aggregations (like: max, min, first..etc.) to a destination bucket.
My current implementation using Redis TimeSeries (in Python) for candle sticks for each stock price looks something like this (using stock XYZ as example again) and no labels for simplicity:
...ANSWER
Answered 2020-Jun-24 at 09:57- There is no option to send more than one aggregation to a downsample series since each timestamp can hold a single. You can utilize labels to query all series at once.
- RedisTimeSeries would be a good solution as it will downsample your data at insertion so querying it would be super fast. It also uses double-delta compression which means your data will require lesser memory than some other solutions. You can even use retention to retire the source data if all you care about is the candlesticks.
QUESTION
I am trying to start a docker container using a redis db that I have a persistent copy saved to a local machine.
I currently have a docker container loading redis with a volume using this docker-compose.yml
but it misses my redis.conf (which contains the loadmodule command) is located in the volume with the rdb file
ANSWER
Answered 2020-Jun-20 at 05:52You can just have docker-compose build your dockerfile directly. Assume your docker-compose file is in folder called myproject . Also assume your dockerfile is in a folder called myredis and that myredis is in the myproject folder. Then you can replace this line in your docker-compose file:

QUESTION
Bussiness Objective
I'm creating a dashboard that will depend on some time-series and I'll use Redis to implement it. I'm new to using Redis and I'm trying to use Redis-Streams to count the elements in a stream.
...ANSWER
Answered 2020-Jan-21 at 16:16While the Redis Stream data structure doesn't support this, you can use a Sorted Set alongside it for keeping track of message ranges.
Basically, for each message ID you get from XADD
- e.g. "1579551316273-0" - you need to do a ZADD conversation:9:ids 0 1579551316273-0
. Then, you can use ZLEXCOUNT
to get the "length" of a range.
