1	# AWS SDK for Java 2.x - AWS Lambda
2
3	## Overview
4
5	AWS Lambda is a compute service that runs code without managing servers. Use this skill to implement AWS Lambda operations using AWS SDK for Java 2.x in applications and services.
6
7	## When to Use
8
9	- Invoking Lambda functions from Java applications
10	- Deploying and updating Lambda functions via SDK
11	- Managing function configurations and layers
12	- Integrating Lambda with Spring Boot applications
13
14	## Quick Reference
15
16	\| Operation \| SDK Method \| Use Case \|
17	\|-----------\|------------\|----------\|
18	\| Invoke \| `invoke()` \| Synchronous/async function invocation \|
19	\| List Functions \| `listFunctions()` \| Get all Lambda functions \|
20	\| Get Config \| `getFunction()` \| Retrieve function configuration \|
21	\| Create Function \| `createFunction()` \| Create new Lambda function \|
22	\| Update Code \| `updateFunctionCode()` \| Deploy new function code \|
23	\| Update Config \| `updateFunctionConfiguration()` \| Modify settings (timeout, memory, env vars) \|
24	\| Delete Function \| `deleteFunction()` \| Remove Lambda function \|
25
26	## Instructions
27
28	### 1. Add Dependencies
29
30	Include Lambda SDK dependency in `pom.xml`:
31
32	```xml
33	<dependency>
34	<groupId>software.amazon.awssdk</groupId>
35	<artifactId>lambda</artifactId>
36	</dependency>
37	```
38
39	See [client-setup.md](references/client-setup.md) for complete setup.
40
41	### 2. Create Client
42
43	Instantiate `LambdaClient` with proper configuration:
44
45	```java
46	LambdaClient lambdaClient = LambdaClient.builder()
47	.region(Region.US_EAST_1)
48	.build();
49	```
50
51	For async operations, use `LambdaAsyncClient`.
52
53	### 3. Invoke Lambda Function
54
55	Synchronous invocation:
56
57	```java
58	InvokeRequest request = InvokeRequest.builder()
59	.functionName("my-function")
60	.payload(SdkBytes.fromUtf8String(payload))
61	.build();
62
63	InvokeResponse response = lambdaClient.invoke(request);
64
65	return response.payload().asUtf8String();
66	```
67
68	See [invocation-patterns.md](references/invocation-patterns.md) for patterns.
69
70	### 4. Handle Responses
71
72	Parse response payloads and check for errors:
73
74	```java
75	if (response.functionError() != null) {
76	throw new LambdaInvocationException("Lambda error: " + response.functionError());
77	}
78
79	String result = response.payload().asUtf8String();
80	```
81
82	### 5. Manage Functions
83
84	Create, update, or delete Lambda functions:
85
86	```java
87	// Create
88	CreateFunctionRequest createRequest = CreateFunctionRequest.builder()
89	.functionName("my-function")
90	.runtime(Runtime.JAVA17)
91	.role(roleArn)
92	.code(code)
93	.build();
94
95	lambdaClient.createFunction(createRequest);
96
97	// Verify function is active before proceeding
98	GetFunctionRequest getRequest = GetFunctionRequest.builder()
99	.functionName("my-function")
100	.build();
101	GetFunctionResponse getResponse = lambdaClient.getFunction(getRequest);
102	if (!"Active".equals(getResponse.configuration().state())) {
103	throw new IllegalStateException("Function not active: " + getResponse.configuration().stateReason());
104	}
105
106	// Update code
107	UpdateFunctionCodeRequest updateCodeRequest = UpdateFunctionCodeRequest.builder()
108	.functionName("my-function")
109	.zipFile(SdkBytes.fromByteArray(zipBytes))
110	.build();
111
112	lambdaClient.updateFunctionCode(updateCodeRequest);
113
114	// Wait for deployment to complete
115	Waiter<GetFunctionConfigurationRequest> waiter = lambdaClient.waiter();
116	waiter.waitUntilFunctionUpdatedActive(GetFunctionConfigurationRequest.builder()
117	.functionName("my-function")
118	.build());
119	```
120
121	See [function-management.md](references/function-management.md) for complete patterns.
122
123	### 6. Configure Environment
124
125	Set environment variables and concurrency limits:
126
127	```java
128	Environment env = Environment.builder()
129	.variables(Map.of(
130	"DB_URL", "jdbc:postgresql://db",
131	"LOG_LEVEL", "INFO"
132	))
133	.build();
134
135	UpdateFunctionConfigurationRequest configRequest = UpdateFunctionConfigurationRequest.builder()
136	.functionName("my-function")
137	.environment(env)
138	.timeout(60)
139	.memorySize(512)
140	.build();
141
142	lambdaClient.updateFunctionConfiguration(configRequest);
143	```
144
145	### 7. Integrate with Spring Boot
146
147	Configure Lambda beans and services:
148
149	```java
150	@Configuration
151	public class LambdaConfiguration {
152	@Bean
153	public LambdaClient lambdaClient() {
154	return LambdaClient.builder()
155	.region(Region.US_EAST_1)
156	.build();
157	}
158	}
159
160	@Service
161	public class LambdaInvokerService {
162	public <T, R> R invoke(String functionName, T request, Class<R> responseType) {
163	// Implementation
164	}
165	}
166	```
167
168	See [spring-boot-integration.md](references/spring-boot-integration.md) for complete integration.
169
170	### 8. Test Locally
171
172	Use mocks or LocalStack for development testing.
