You have to write record one-by-one, but you can use batch read to fetch many keys at once. [https://www.aerospike.com/docs/client/c/usage/kvs/batch.html](https://www.aerospike.com/docs/client/c/usage/kvs/batch.html) ---

There is a configurable limit to the number of records you can fetch per batch request. See the defaults under this page [https://www.aerospike.com/docs/guide/batch.html](https://www.aerospike.com/docs/guide/batch.html) the reason its limited by default is that it can overload the client easily. ---
