# Microsoft Azure Kusto (Azure Data Explorer) SDK for Java
|
|

master: [](https://msazure.visualstudio.com/One/_build/latest?definitionId=57651)

|
|
|
|
This is the Microsoft Azure Kusto client library which allows communication with Kusto to bring data in (ingest) and query information already stored in the database.
|
|
This library contains 3 different modules:
|
|
- data: The main client that allows interaction with Kusto, including creating a connection, issuing (control) commands and querying data
|
|
- ingest: Provides an easy way to bring data into Kusto
|
|
- quickstart: Self-contained, configurable and runnable sample app for easily getting started with the SDK
|
|
- samples: Sample code implementing various scenarios
|
|
|

# Install
|
|
|
|
## Maven
|
|
|
|
This method is the easiest to follow, just add the following dependency to your pom.xml (with the right version tag from maven central):
|
|
```xml
|
|
<dependency>
|
|
<groupId>com.microsoft.azure.kusto</groupId>
|
|
<artifactId>kusto-ingest</artifactId>
|
|
<version>[see badge below]</version>
|
|
</dependency>
|
|
```
|
|
[](https://maven-badges.herokuapp.com/maven-central/com.microsoft.azure.kusto/kusto-ingest)
|
|
|
|
|
|
## Clone
|
|
Download the source code, compile and install locally.
|
|
|
|
One way to do this is by using maven like in the following example:
|
|
```
|
|
git clone git://github.com/Azure/azure-kusto-java.git
|
|
cd azure-kusto-java
|
|
mvn install
|
|
```
|
|
|
|
# Prerequisites
|
|
|
|
- A Java Developer Kit (JDK), version 11 or later
|
|
- Maven
|
|
|
|
# Samples
|
|
|
|
- [Execute a query](samples/README.md#execute-query-sample)
|
|
- [Ingest a file](samples/README.md#file-ingestion-sample)
|
|
- [Check status of an ingest operation](samples/README.md#query-table-status-sample)
|
|

|
## Using A Proxy
|
|
The SDK includes support for the built-in proxy system properties in java.
|
|
For example, when the address of your proxy server is 1.2.3.4:8989, you can run:
|
|
`java -ea -Dhttp.proxyHost=1.2.34 -Dhttp.proxyPort=8989 -Dhttps.proxyHost=1.2.3.4 -Dhttps.proxyPort=8989`
|
|
And the SDK will know to use these values automatically.
|
|
|
|
Alternatively, you can define a proxy programmatically when creating a client, using `HttpClientProperties`:
|
|
```java
|
|
HttpClientProperties httpClientProperties = HttpClientProperties.builder()
|
|
.proxy(new HttpHost("1.2.3.4", 8989))
|
|
.build();
|
|
|
|
Client = ClientFactory.createClient(<engine_connection_string>, httpClientProperties);
|
|
// Or for DM:
|
|
IngestClient ingestClient = IngestClientFactory.createClient(<dm_connection_string>, httpClientProperties)
|
|
|
|
```
|
|
|
|
## Best Practices
|
|
See the SDK [best practices guide](https://docs.microsoft.com/azure/data-explorer/kusto/api/netfx/kusto-ingest-best-practices), which though written for the .NET SDK, applies similarly here.
