About neo4j-admin.bat import——WARNING ：heap size is too small

[bupianlizhugui]

I have downloaded Yelp data and created a Neo4j Import Tool CSV file, but when using the neo4j-admin.bat import command in a window environment, I get a warning. What does this "heap" mean? Will it affect my data import?

Heap size is the available memory for performing whatever you need to execute.

The heap memory size is determined by the parameters in $NEO4J_HOME/conf/neo4j.conf , namely dbms.memory.heap.initial_size and dbms.memory.heap.max_size providing the heap size as a number and a unit, for example 16G . It is recommended to set these two parameters to the same size.
