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/rpc.md, doc/rpc-streaming.md and doc/rpc-compression.md

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

Class Documentation

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.

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.
isolation_function_alternatives	isolate_connection
size_t	max_memory	Maximum amount of memory that may be consumed by all requests

struct seastar::rpc::client_options

Class Members
factory *	compressor_factory
sstring	isolation_cookie	Configures how this connection is isolated from other connection on the same server. See also resource_limits::isolate_connection

isolation_config seastar::rpc::default_isolate_connection ( sstring isolation_cookie )

Default isolation configuration - run everything in the default scheduling group.

In the scheduling_group that the protocol::server was created in.
