title="Migration to 0.10.0" id="0-10-0">

12+
<p>
13+
Version <code>0.10.0</code> brings some changes that require a migration:
14+
</p>
15+
<list>
16+
<li>
17+
<code>waitForServices</code> parameter in kRPC config is deprecated
18+
and should be replaced with <a href="configuration.topic#connector-dsl"/>
19+
</li>
20+
<li>
21+
As a continuation of the previous point, the backpressure mechanism is now introduced.
22+
You may encounter slowdowns by default when using streams.
23+
Use <a href="configuration.topic#connector-dsl"/>
24+
to configure better suited buffer sizes.
25+
</li>
26+
<li>
27+
For Ktor kRPC integration -
28+
<code>public fun Route.rpc</code> functions now accept a suspending function parameter
29+
instead of a regular one.
30+
</li>
31+

<p>
75-
<code>waitForServices</code> parameter is available for both client and server.
76-
It specifies the behavior for an endpoint in situations
77-
when the message for a service is received,
78-
but the service is not present in <code>KrpcClient</code> or <code>KrpcServer</code>.
79-
If set to <code>true</code>, the message will be stored in memory,
80-
otherwise, the error will be sent to a peer endpoint,
81-
saying that the message was not handled.
82-
Default value is <code>true</code>.
75+
Connector is a part of kRPC that is responsible for sending and receiving data over the network.
76+
You can configure the following parameters:
8377
</p>
78+
<list>
79+
<li>
80+
<code>waitTimeout</code> - timeout for waiting for a service to be registered.
81+
Sometimes services can be registered after the server starts,
82+
and after the first requests starts to arrive from a peer.
83+
This parameter defines how long the server will wait for a service to be registered.
84+
<br/>
85+
The default value is <code>Duration.INFINITE</code>.
86+
<br/>
87+
Also, available a value of <code>dontWait()</code>.
88+
</li>
89+
<li>
90+
<code>callTimeout</code> - timeout for processing one message.
91+
<br/>
92+
The default value is <code>Duration.INFINITE</code>.
93+
</li>
94+
<li>
95+
<code>perCallBufferSize</code> - size of the buffer for one call.
96+
Call can be a stream or a single message.
97+
This effectively provides a backpressure mechanism.
98+
If a peer is slow to process the message during a call,
99+
the buffer will be filled up and
100+
the sender will wait before sending more messages.
101+
<br/>
102+
Note that this is <b>per call</b>, not per connection.
103+
<br/>
104+
The default value is <code>1</code>.
105+
</li>
106+
</list>
107+
<p>
108+
Example:
109+
</p>
110+
<code-block lang="kotlin">
111+
rpcClientConfig {
112+
connector {
113+
waitTimeout = 10.seconds
114+
callTimeout = 60.seconds
115+
perCallBufferSize = 1000
