I have dumped a set of files (csv as well as json) from an existing Oracle instance and would like to load that data into Aerospike. I have Aero 3 and have a 3-node cluster configured for “in-memory with disk persistance”. Luckily it’s not a large data set, but what’s the mechanics to load data into Aerospike efficiently? My client is Java btw. Do I have to basically write my own program for that?

Hi Rajnairkansas,

I was wondering if you gotten the chance to check out the documentation part for Client guides?

I did - which particular section are you referring to. I would imagine that a common requirement would be to migrate data or import from some existing data source such as MySQL or Oracle. Which is exactly the situation I have. I can export out to CSV or JSON, but what’s a mechanism to bulk load data into Aerospike?

Aerospike has now put out a bulk loader. It is multi-threaded so will hopefully give you the performance you need.
