256MB RAM limit - how can I estimate if we will reach it?

I was wondering about the 256MB RAM limit in the startup program.
Is that something we will encounter? What increases the memory consumption, large database / large queries or responses?
Based on similar applications that I know of in that field, we will store around 1.5 TB of data, and around 1B nodes and edges.


Hi @adamklein.mail,
Yes, large databases, complex queries or queries going through a large chunk of data would all account for memory consumption.
For a 1.5TB database and 1B nodes and relationships, you will definitely need much more memory than 256MB.
I would recommend you take a loot at Neo4j Hardware Sizing Calculator.
