Memory Requirement?

[apremgeorge]

Hi,
May I know the RAM requirement for processing most of the traversal queries and run graph algorithms for 5 million nodes (9 labels) with 14million relationships (14 types), I have loaded the data from elastic, and data keep coming in like 10k per day

May I know your recommendation for server please,

I have to perform queries, for example shortest path, traversals, and run most of the graph algorithms, I would expect the response times as low as possible.

Thanks

Hi @Thomas_Silkjaer

In my local, I have set heap to 4g for

I keep running into memory issue with 23k nodes and 61k relation, May I know why and how much required, I'm in windows with 16GB RAM,i7 4cores

Thanks

1. do you have created an index on: :PayTransactions(TrxId)?
2. don't return those to the poor browser, those are potentially many paths, i.e. add a limit and add an upper limit to your shortest path too

Thanks @michael.hunger

@apremgeorge - for the algorithms, you can use the memrec procedure to estimate the memory you'll need to load the data and execute specific algorithms. See: https://neo4j.com/docs/graph-algorithms/current/projected-graph-model/memory-requirements/
