Hi,


In our use case, we need to do a lot of data importing/updating everyday ( 
billions of nodes/relationships ). 


What's the way to tuning the configuration to boost performance?


Does the kernel config help data ingestion? Settings like '
*neostore.propertystore.db.strings.mapped_memory*' is for query cache only, 
am I correct? Does these parameter help with data import performance?   



One more question, how does neo4J embedded do with concurrent data 
importing? I have multiple threads writing to embedded database at the same 
time, I always get locking exception that multiple threads try to lock the 
same relationship. What's the recommend way for multiple threads data 
ingestion?



Thanks,


Guan
