What does this skill do, and when should you use it?
This skill supports Java developers building real-time streaming and event-driven applications with the Azure Event Hubs SDK. It covers producers, consumers, asynchronous clients, batching, partition routing, event properties, and event positions. For production processing, it demonstrates EventProcessorClient with Blob checkpoint storage, load balancing, and checkpoint updates. It also addresses Entra ID credentials, transient errors, cleanup, and relevant environment variables.
Supplies Maven dependency declarations and Java implementation patterns for creating synchronous or asynchronous producers and consumers, sending individual or batched events, targeting partitions or partition keys, receiving events with sequence and offset metadata, running EventProcessorClient with Blob checkpoint storage, processing event batches, querying Event Hub and partition properties, selecting starting positions, handling transient AMQP errors, and closing clients.
- A Java backend developer ingesting high-volume data into Azure Event Hubs can use the producer and EventDataBatch examples.
- An application developer consuming live events from a particular partition can use the synchronous or asynchronous consumer patterns.
- A team building a production event-processing service can use EventProcessorClient with Blob checkpoint storage and checkpoint updates.
- A developer needing ordering for a customer or business entity can use a partition key.
- A consumer that must start from the beginning, the latest event, a specific offset, sequence number, or time can use EventPosition.
How do you install this skill?
- The main document lists azure-messaging-eventhubs 5.19.0 and checkpointstore 1.20.0, while references/examples.md lists 5.21.0 and 1.21.0; versions should be reconciled and compatibility verified.
- Connection-string examples may contain long-lived credentials; use secure secret storage, managed identity, least privilege, and avoid logging event contents or credentials.
- The snippets are not a complete compilable project; production use requires validation of imports, API signatures, retry behavior, shutdown flow, checkpoint semantics, and permissions.
- Network access
Javacom.azure:azure-messaging-eventhubs 5.19.0
Run npx skills add microsoft/skills and select the skill in the wizard. The collection installs into the selected agent directory, such as .github/skills/ for GitHub Copilot; the source skill is located at .github/plugins/azure-sdk-java/skills/azure-eventhub-java/SKILL.md. Add com.azure:azure-messaging-eventhubs:5.19.0 to the project. Production checkpointing additionally uses com.azure:azure-messaging-eventhubs-checkpointstore-blob:1.20.0.

How do you use this skill?
Once installed, send your agent any of these to trigger it:
- Build an EventProcessorClient in Java with Blob checkpoint storage
- Implement partitioned batch sending with the Java Event Hubs SDK.
After installing the skill into the agent configuration directory, trigger it with a request such as “Build an EventProcessorClient in Java with Blob checkpoint storage” or “Implement partitioned batch sending with the Java Event Hubs SDK.” Configure either a connection string or DefaultAzureCredential and provide the Event Hub name; production processing also requires checkpoint-store configuration.
What are this skill's strengths and limitations?
- Covers the main Java SDK patterns for producers, consumers, async clients, and EventProcessorClient.
- Includes practical guidance for batching, partition keys, checkpointing, error handling, and resource cleanup.
- Shows both connection-string and DefaultAzureCredential authentication approaches.
- Provides concrete Maven coordinates, versions, and copyable Java examples.
- The examples require access to Azure Event Hubs and appropriate credentials, so they cannot run independently of the Azure service.
- Production checkpointing adds an Azure Blob Storage dependency and configuration requirement.
- The supplied material does not provide an independent test scenario or complete runnable project for this individual skill.

How did FollowSkills review this skill?
The skill provides both connection-string and DefaultAzureCredential/Managed Identity patterns and recommends specific credentials in production, showing some authentication separation. It does not document secret storage, log redaction, least-privilege RBAC, sensitive event-data handling, confirmation for external sends/storage, or rollback, so points are deducted.
It covers production processing, batching, asynchronous consumption, error handling, and client cleanup, making the main paths plausible. However, only static documentation is available; no skill-specific reproducible tests are shown, dependency versions conflict between the main file and reference, and some snippets omit imports, edge-case handling, or lifecycle details, so the score is conservatively reduced.
The name, audience, and trigger phrases are clear, with local/production, sync/async, partition, and checkpoint scenarios. Boundaries, input/output contracts, network and permission prerequisites, and Chinese-language guidance are not clearly stated; the function also depends on reachable Azure services, so points are deducted.
The documentation is layered across installation, clients, patterns, error handling, cleanup, and best practices, with a reference example file, MIT license, author, and version metadata. The main and reference files use inconsistent versions, and there is no changelog, explicit maintenance/update path, FAQ, troubleshooting section, or known-limitations disclosure, so it is not full marks.
The material supplies directly useful templates for EventProcessorClient, batching, partition routing, checkpointing, event positions, and error handling, so it plausibly completes the core coding task. Static review cannot verify compilation, API/version compatibility, or end-to-end usability; configuration, permissions, imports, and business processing still require completion, so the score is capped and reduced.
Concrete Maven coordinates, versions, code examples, environment variables, and repository CI/test material provide some auditability. There is no skill-specific test suite with execution results or corroborating evidence, and nothing was executed in this review, so the score stays at the static-review ceiling.
