Got question is there any plan to support byte[] data in nebula? From the graph? The thrift api supports and I was thinking of encrypted values.

Has anyone tried to set Nebula option enable_partitioned_index_filter and max_edge_returned_per_vertex?

Using Nebula helm charts?

@wey with the absence of a unique constraint or index.. is there a good

merge

type query that can try to reduce the possibly of duplicates.. where Nebula does a search before an insert.

Did anyone try log clean up using Cronjob? Can I get code snippet please?

hello! anyone here tried using ldbc to benchmark nebula?

Hi I have installed nebulagraph standalone for linux by building from source. Graph service is running in 127.0.0.1:9669. However I'm not able to make the nebula client work. I'm trying the exmaple code SessionExample.cpp but the execution gets stuck in ConnectionPool init function and doesnt proceed after that. Aybody know how to fix this issue? Thank you

Hello, do you have estimations for maximum data size with Nebula? Such as N TB graph tested, number of V, E

Hi everyone, Why The

WHERE

clause cannot be used in an

OPTIONAL MATCH

clause in version 3.4 ?

I want to rebuild the new index, but when the rebuild fails, it is recorded in the logs.

Hi all! I've never worked with Nebula before and I'm not quite sure how to get the Community version in Azure and if I have to pay for the license. If you have any experience of deploying to azure or any references, I would be very grateful!

Hi. is this repo compatible with the latest version of nebula graph? https://github.com/nebula-contrib/ngbatis

Is there anything similar to ngbatis but for rust or golang?

Hi <!here> I have a 3

storaged

host based nebula graph cluster deployment, which has a large amount of data. As per the documentation: https://docs.nebula-graph.io/3.4.1/5.configurations-and-logs/1.configurations/4.storage-config/#storage_configurations_for_large_dataset I have set

enable_partitioned_index_filter=true

in every storage nodes

nebula-storaged.conf

. Although 2 hosts use low amount RAM (expected behavior), the third host overloads the RAM and crashes. Please suggest if there is anything missing to get the cluster working with low RAM allocations.

Hi! Is there any plan to add a caching layer ? Or what caching layers have been implemented together with Nebula.

Additionally, has anyone read the recent ByteGraph paper over the distributed graph db built by ByteDance? https://vldb.org/pvldb/vol15/p3306-li.pdf What are the main differences between Nebula Graph and Byte Graph in architecture and performance?

Hi! Can someone please explain to me the results shown in this performance comparison between NebulaGraph, HugeGraph, and Neo4j? https://www.nebula-graph.io/posts/performance-comparison-neo4j-janusgraph-nebula-graph Why does NebulaGraph take 2.035s to perform a one-hop query with 1 billion edges when it takes less than 1s to perform the one-hop query with 8 billion edges? Similarly, why would any query with a larger graph data size be significantly faster than a query with a smaller graph data size?

Hi. Are there issues with indexing if the db is compacted or if bloom filter is active ?

Has anyone tried to enable SSL using nebula-operator? We are stuck as there is no way to let the pods access the secrets in the K8S secret store!!!

Any idea when will nebule-operator support v3.5.0, last release was in February 2023?

We are facing a significant issue with the python-client(not ipython ngql extension) library of your graph database products. When using the library to run queries, it does not provide any error feedback, making it challenging to identify and address problems. As a result, we are currently resorting to using the console for queries, but this is not a viable long-term solution since we need to access the database through the python-client for API calls. This issue is hindering the smooth functioning of our backend. If anyone can help please DM me

How do I fix this issue, "Host not enough!"? It occurs when I attempt to create a schema in the gui console

Hello everyone , I'm just new for Nebula Graph and facing some issue related to query for update the properties of vertex like other graph database use this query to update the specific property of vertex with the help of cypher language I have two vertex with given specific vid and also having relation between them and now I want to update the property of Room tag vertex with vid "room1" wan to change but unfortunately it wont work so I just want to know is there any possibility or having query syntax which checking the relation first like this building have this specific room id then update the room property . MATCH (bBuilding{id "building01"})-[h:having]->(rRoom{id "room1"}) SET r.Roomname = 'King' RETURN r

Hi all, is there anyway to use NebulaGraph in a spring boot application ? Is spring-data-neo4j compatible with NebulaGraph, since it's based on openCypher ? How about spring-data-jdbc ? Are there plans to implement a "spring-data-nebula" integration ? Any other suggestions ? Please help! Thank you :)

Hey, Im considering

Nebula Graph

for a new

OpenTelemetry

big data project. And I wonder if

Nebula graph

can handle it. the main

Vertex

will be called

Span

and we expect to add 6K spans per second. Each

Span

has an average of 25 attributes. some are intrinsic and will be part of the

Vertex

. The other can change, so I thought It will be best to create an

Attribute Vertex

and link each

Span

to its related attributes. That mean around 24K

Edges

per second. Assuming 1 month of data gathering, we can expect

16 bil Span

and

400 bil Attributes

There are other `Vertex`/`Edges` but they wont reach such numbers. There will be max of 20 simultaneous querying users. Query should be fast enough and measured in few seconds. Can

Nebula Graph

handle the `Write`/`Storage`/`Read` of such scenario?
