Hi Boxuan, Issue seems to occurs when edge properties are retrieved: cache has expected size with g.V().outE().id() an not when I do g.V().outE().valueMap(); I am able to reproduce with following groo

Hi, I try to use Database Level Caching as described in https://docs.janusgraph.org/basics/cache/ but it seems to use more memory than the configured threshold ( cache.db-cache-size ). Does anyone use

Hi all, I have a question about locking data through Janusgraph. Here’s the problem: * We have a vertex with the label “type” with several properties * Types have one edge “hasVersion” to a vertex wit

I have rfd data which is in turtle or xml format. Now the data is having the vertex property name in the form of URL so when I upload that data to Janus graph it converts those URL values to ns1,ns2 a

GraphSON is a serialization format from TinkerPop to serialize graph objects. It doesn't serialize properties as simple key-value pairs. To try out how vertex properties with meta properties are seria

The docs describes that properties can have properties too. https://docs.janusgraph.org/advanced-topics/advschema/#multi-properties For example: alice -age-> 23 -source-> foo -address-> "something" -s

Hi! I am trying write select-query and my perfomance is very slow when I call method toList(). How I can improve this perfomace ? My example: long start; long end; try (GraphTraversalSource g = graph.

Hi, I am new to Janusgraph and want to try how I can interact with it using Node Js. Do I need to configure my gremlin server to allow remote connections? I am not sure how exactly that is to be done.
