Best way to implement batch reads in aerospike

Question

I have a scenario where for each request, I've to make a batch get of atleast 1000 keys.

Currently I'm getting 2000 requests per minute and this is expected to rise.

Also I've read that batch get of aerospike internally makes individual request to server concurrently/sequentially.

I am using the aerospike as a cluster (running on SSD). So is this efficient to write UDF (user defined method) in lua for making a batch request, and aggregating the results at server level instead of multiple hits from client

Kindly suggest if default batch get of aerospike will be efficient or I've to do something else.

Batch read is the right way to do it. Results are returned in the order of keys specified in the list. Records not found will return null. Client parallel-izes the keys by nodes - waits (there is no callback in client unlike Secondary Index or Scan) and collects the returns from all nodes and presents them back in the client in original order. Make sure you have adequate memory in the client to hold all the returned batch results.
