API Overview

Library Overview

Blocking Operations

Each blocking kinetic interface operation (e.g. ki_del) encompasses the end to end logic of:

1. Access connection configuration

2. Validate existence of function arguments

3. Validate values of function arguments

4. Create the kio (kinetic IO) structure

5. Populate the request data of the kio structure (`kio->kio_sendmsg`)

6. Pack request data (into protobufs) and send to the kinetic server

7. Receive the response data from the kinetic server (`kio->kio_recvmsg`)

8. Unpack response data into data structure (e.g. `kv_t`, `keyrange_t`, etc.)
