How to synchronise data from different modules Redis

Asked 2021-Dec-27 at 19:39

I am new to redis and I wanted to know if there was a way to synchronise my data from my redisJson and my redisGraph

For example, I have a user un a hash or a redisJson and I have this same user in my redisGraph

How do I synchronise this user everywhere so that when I change is email in the hash it changes every where.

I know that this exists for mongoDb and neo4j, there must be something similar for Redis

You can use [RedisGears][1] to register on any JSON change and synchronously update the Graph accordingly.

See a similar example that listen to Hash changes and update the graph accordingly: https://github.com/RedisGears/MultiModelExample

You can also see more examples here: https://oss.redis.com/redisgears/examples.html

Export/import/backup RedisGraph database

Asked 2021-Aug-09 at 13:18

I've got a little too far with RedisGraph and now it's about to ship in production.

Therefore I need to export and import some data between servers and also to create backups. I'm using the open source community version (not the Redis Entreprise).

How would you recommend to proceed backups and imports/exports?

Thanks for your feedbacks!

ANSWER

Answered 2021-Aug-09 at 13:18

RedisGraph stores each graph in a single Redis key, so traditional Redis persistency methods can be used to persist and migrate data.

Backups are usually managed using RDB files or a combination of both the RDB and AOF strategies, these are described here.

If your Redis keyspace should be entirely duplicated or only consists of graph keys, you can copy the RDB file between servers, otherwise you can export and import graph keys with the DUMP and RESTORE commands.

RedisGraph doesn't have an equivalent to the mergeNodes functionality, nor does it support changing the endpoint of an existing edge.

As such, you will need to delete the original edge and introduce a new one:

Architecture and querying in RedisGraph

Asked 2021-Jul-12 at 08:41

I'm new to graphs, RedisGraph and Cypher and this took me a few hours without solving.

I have users paying other users. A payment can be deposited from a user. Some other user can eventually withdraw that deposit, but a deposit can also never be withdrawn.

I ended up with this:

ANSWER

Answered 2021-Jul-10 at 17:16

what would be a better architecture?

I believe you refer to what is called "graph modelling". Graph modelling in the basic form consists out of deriving entities and verbs out of sentences

entities -> candidate labels
verbs -> candidate relationship types

A payment can be deposited from a user. Some other user can eventually withdraw that deposit,

entities: Payment/Deposit/Transaction (I assume you use this interchangeably) and User
verbs: deposit and withdraw

So you did a good job nailing that.

With regards to your second question. Given two transactions

I am trying to use the redisgraph-bulk-loader to load the dataset into the RedisGraph instance running in a docker container. However, it returns with IndexError: list index out of range which I do not understand. I have read the documentation and my CSV files are valid.

The error you're encountering occurs at this line - https://github.com/RedisGraph/redisgraph-bulk-loader/blob/master/redisgraph_bulk_loader/entity_file.py#L233 .

At this point, we are trying to retrieve the type specified after the colon in a specific field of a header line. As such, an IndexError indicates that no colon was found in one of the fields.

Looking at relationship.csv, I see that the header row ends with "properties__title","properties__uri","end__labels__002". These columns should have a colon-separated type, like the preceding fields.
