### Updates
#### 1. `cache-suffix` Parameter
**Design Purpose:**
- Support cache isolation for different build scopes, optimizing cache hit
rate and storage efficiency
- Allow independent cache spaces for different build types (full build, E2E
tests, etc.)
**Parameter Values:**
| Value | Usage Scenario |
|---|---|
| `full` | Full build (default) |
| `e2e-sql` | E2E SQL tests |
| `e2e-agent` | E2E Agent tests |
| `e2e-operation` | E2E Operation tests |
**Cache Key Format:**
```
{cache-prefix}-maven-{cache-suffix}-{hashFiles('**/pom.xml')}
```
**Restore Keys Strategy (Multi-level Fallback):**
```
1. {cache-prefix}-maven-{cache-suffix}-
2. {cache-prefix}-maven-full-
3. {cache-prefix}-maven-
4. {cache-prefix}-
```
#### 2. Shared Composite Actions
**New Actions:**
| Action | Purpose |
|---|---|
| `setup-build-environment` | Unified Java and Maven cache setup |
**setup-build-environment Parameters:**
| Parameter | Required | Default | Description |
|---|---|---|---|
| `java-version` | No | `17` | Java version |
| `distribution` | No | `temurin` | Java distribution |
| `cache-prefix` | No | `apache-shardingsphere` | Cache key prefix |
| `cache-suffix` | No | `full` | Cache key suffix |
**Why use `actions/cache` instead of `setup-java` built-in cache:**
- Precise control over cache paths, excluding project's own built jars
(`!~/.m2/repository/org/apache/shardingsphere`)
- Avoid cache pollution and reduce cache size
#### 3. Remove `github.sha` from Cache Key
e.g.
**Original Key:**
```
apache-shardingsphere-maven-third-party-e2e-cache-${{ github.sha }}
```
**New Key:**
```
apache-shardingsphere-maven-e2e-sql-{pom.xml hash}
```
**Benefits:**
- Improved cache hit rate (different commits can reuse the same dependency
cache)
- Reduced cache storage pressure (avoid creating isolated cache for each
commit)
