rpc - remote procedure call framework

Detailed Description

rpc is a framework that can be used to define client-server communication protocols. For a high-level description of the RPC features see doc/, doc/ and doc/

The entry point for setting up an rpc protocol is seastar::rpc::protocol.

◆ seastar::rpc::isolation_config

struct seastar::rpc::isolation_config
Class Members
scheduling_group sched_group

Specifies a scheduling group under which the connection (and all its verb handlers) will execute.

◆ seastar::rpc::resource_limits

struct seastar::rpc::resource_limits
Class Members
typedef function< future< isolation_config >(sstring isolation_cookie)> asyncronous_isolation_function
typedef variant< syncronous_isolation_function, asyncronous_isolation_function > isolation_function_alternatives
typedef function< isolation_config(sstring isolation_cookie)> syncronous_isolation_function

Configures isolation for a connection based on its isolation cookie. May throw, in which case the connection will be terminated.

Class Members
size_t basic_request_size Minimum request footprint in memory.
unsigned bloat_factor Serialized size multiplied by this to estimate memory used by request.

size_t max_memory

Maximum amount of memory that may be consumed by all requests
