    Ingest, buffer, store, and process your stream in real time to get actionable insights. Event Hubs uses a partitioned consumer model, enabling multiple applications to process the stream concurrently and letting you control the speed of processing.Capture your data in near-real time in an Azure Blob storage or Azure Data Lake Storage for long-term retention or micro-batch processing. You can achieve this behavior on the same stream you use for deriving real-time analytics. Setting up capture...

    With Event Hubs, you can start with data streams in megabytes, and grow to gigabytes or terabytes. The Auto-inflate feature is one of the many options available to scale the number of throughput units to meet your usage needs.

    Event Hubs for Apache Kafka ecosystems enables Apache Kafka (1.0 and later) clients and applications to talk to Event Hubs. You do not need to set up, configure, and manage your own Kafka clusters.With a broad ecosystem available in various languages (.NET, Java, Python, Go, Node.js), you can easily start processing your streams from Event Hubs. All supported client languages provide low-level integration. The ecosystem also provides you with seamless integration with Azure services like Azur...

    Event Hubs contains the following key components: 1. Event producers: Any entity that sends data to an event hub. Event publishers can publish events using HTTPS or AMQP 1.0 or Apache Kafka (1.0 and above) 2. Partitions: Each consumer only reads a specific subset, or partition, of the message stream. 3. Consumer groups: A view (state, position, or offset) of an entire event hub. Consumer groups enable consuming applications to each have a separate view of the event stream. They read the strea...

    Messagesoften carry information that pass the baton of handling certain steps in a workflow or a processing chain to a different role inside a system. Those messages, like a purchase order or a monetary account transfer record, may express significant inherent monetary value. That value may be lost and/or very difficult to recover if such a message were somehow lost in transfer. The transfer of such messages may be subject to certain deadlines, might have to occur at certain times, and may have to be processed in a certain order. Messages may also express outright commands to perform a specific action. The publisher may also expect that the receiver(s) of a message report back the outcome of the processing, and will make a path available for those reports to be sent back. This kind of contractual message handling is quite different from a publisher offering facts to an audience without having any specific expectations of how they ought to be handled. Distribution of such facts is be...

    Eventsare also messages, but they don’t generally convey a publisher intent, other than to inform. An event captures a fact and conveys that fact. A consumer of the event can process the fact as it pleases and doesn’t fulfill any specific expectations held by the publisher. Events largely fall into two big categories: They either hold information about specific actions that have been carried out by the publishing application, or they carry informational data points as elements of a continuously published stream. Let’s first consider an example for an event sent based on an activity. Once a sales support application has created a data record for a new sales lead, it might emit an event that makes this fact known. The event will contain some summary information about the new lead that is thought to be sufficient for a receiver to decide whether it is interested in more details, and some form of link or reference that allows the obtaining of those details. The ability to subscribe to t...

    Applications emit action events and data point events as messages to provide insights into what work they do and how that work is progressing. Other messages are used to express commands, work jobs, or transfers of control between collaborating parties. While these are all messages, the usage scenarios are so different that Microsoft Azure provides a differentiated, and yet composable, portfolio of services.

    Because it’s often difficult to draw sharp lines between the various use-cases, the three services can also be composed. (Mind that Event Grid is still in early preview; some of the composition capabilities described here will be made available in the coming months) First, both Service Bus and Event Hub will emit events into Event Grid that will allow applications to react to changes quickly, while not wasting resources on idle time. When a queue or subscription is “activated” by a message after sitting idle for a period of time, it will emit a Grid event. The Grid event can then trigger a function that spins up a job processor. This addresses the case where high-value messages flow only very sporadically, maybe at rates of a handful of messages per day, and to keep a service alive on an idle queue will be unnecessarily costly. Even if the processing of said messages were to require substantial resources, the spin-up of those resources can be anchored on the Event Grid event trigger...

    Azure Messaging provides a fleet of services that allows application builders to pick a fully-managed service that best fits their needs for a particular scenario. The services follow common principles and provide composability that doesn’t force developers into hard decisions choosing between the services. The core messaging fleet that consists of Event Hubs, Event Grid, Service Bus, and the Relay is complemented by further messaging-based or message-driven Azure services for more specific scenarios, such as Logic Apps, IoT Hub and Notification Hubs. It’s quite common for a single application to rely on multiple messaging services in composition, and we hope that we could provide some orientation around which of the core services is most appropriate for each scenario.

  2. How to monitor Event Hub in Azure with AIMS

    www.aims.ai › resources › how-to-monitor-event-hub

    An event ingestor is a component or service that sits between event publishers and event consumers to decouple the production of an event stream from the consumption of those events. Event Hubs provides a unified streaming platform with time retention buffer, decoupling event producers from event consumers.

    Azure Data Explorer supports several ingestion methods, each with its own target scenarios, advantages, and disadvantages. Azure Data Explorer offers pipelines and connectors to common services, programmatic ingestion using SDKs, and direct access to the engine for exploration purposes.

    Before you start to ingest data, you should ask yourself the following questions. 1. Where does my data reside? ​ 2. What is the data format, and can it be changed? ​ 3. What are the required fields to be queried? ​ 4. What is the expected data volume and velocity? ​ 5. How many event types are expected (reflected as the number of tables)? ​ 6. How often is the event schema expected to change? ​ 7. How many nodes will generate the data? ​ 8. What is the source OS? ​ 9. What are the latency requirements? ​ 10. Can one of the existing managed ingestion pipelines be used? ​ For organizations with an existing infrastructure that are based on a messaging service like Event Hub and IoT Hub, using a connector is likely the most appropriate solution. Queued ingestion is appropriate for large data volumes.

    For all ingestion methods other than ingest from query, format the data so that Azure Data Explorer can parse it. 1. The supported data formats are: TXT, CSV, TSV, TSVE, PSV, SCSV, SOH​, JSON (line-separated, multi-line), Avro, Orc and Parquet​. 2. Supports ZIP and GZIP compression.

    The effective retention policy of ingested data is derived from the database's retention policy. See retention policy for details. Ingesting data requires Table ingestor or Database ingestorpermiss...
    Ingestion supports a maximum file size of 5 GB. The recommendation is to ingest files between 100 MB and 1 GB.

    Schema mapping helps bind source data fields to destination table columns. 1. CSV Mapping (optional) works with all ordinal-based formats. It can be performed using the ingest command parameter or pre-created on the tableand referenced from the ingest command parameter. 2. JSON Mapping (mandatory) and Avro mapping (mandatory) can be performed using the ingest command parameter. They can also be pre-created on the tableand referenced from the ingest command parameter.
