2011-11-23 Thread Vinicius Carvalho
Hi there, I've posted a few days ago about the POC I'm doing here at my company. I have some initial numbers and I'd like to ask for some help here in order to promote neo4j here in LMI Ericsson. I've loaded a mySQL db with a really simple entity, that pretty much only represents a node and

Hi Gustavo, I had some questions with the batch insert as well. After getting help here :D What I'm doing is using the batchInserterImpl to load the neo instance, I'll use the REST API later for querying. So far, our lab has a neo4j instance running in a single node blade server with tons of RAM
