The InfluxDB v3 [`influxdb3-java` Java client library](https://github.com/InfluxCommunity/influxdb3-java) integrates with Java application code
|

to write and query data stored in an {{% product-name %}} bucket.
|
||||
The InfluxDB v3 [`influxdb3-java` Java client library](https://github.com/InfluxCommunity/influxdb3-java) integrates
|
||||
with Java application code to write and query data stored in an {{% product-name %}}
|
||||
bucket.
|
||||
|
||||
The documentation for this client library is available on GitHub.
|
||||
InfluxDB client libraries provide configurable batch writing of data to {{% product-name %}}.
|
||||
Client libraries can be used to construct line protocol data, transform data from other formats
|
||||
to line protocol, and batch write line protocol data to InfluxDB HTTP APIs.
|
||||
|
||||
<a href="https://github.com/InfluxCommunity/influxdb3-java" target="_blank" class="btn github">InfluxDB v3 Java client library</a>
|
||||
InfluxDB v3 client libraries can query {{% product-name %}} using SQL or InfluxQL.
|
||||
The `influxdb3-java` Java client library wraps the Apache Arrow `org.apache.arrow.flight.FlightClient`
|
||||
in a convenient InfluxDB v3 interface for executing SQL and InfluxQL queries, requesting
|
||||
server metadata, and retrieving data from {{% product-name %}} using the Flight protocol with gRPC.
|
||||
|
||||
## Setup & Installation
|
||||
|
||||
Create a command line java application using Maven or Gradle.
|
||||
|
||||

|
||||
|
||||
Build the project and then run the executable .jar file with this [JVM Flag](https://arrow.apache.org/docs/java/install.html).
|
||||
```sh
|
||||
java --add-opens=java.base/java.nio=org.apache.arrow.memory.core,ALL-UNNAMED -jar target/PROJECT_NAME.jar
|
||||
Replace the following:
|
||||
|
||||
- {{% code-placeholder-key %}}`DATABASE_NAME`{{% /code-placeholder-key %}}: your {{% product-name %}} [bucket](/influxdb/cloud-serverless/admin/buckets/)
|
||||
- {{% code-placeholder-key %}}`API_TOKEN`{{% /code-placeholder-key %}}: a local environment variable that stores your [token](/influxdb/cloud-serverless/admin/tokens/)--the token must have read and write permission to the specified bucket.
|
||||
|
||||
### Run the example to write and query data
|
||||
|
||||
1. Build an executable JAR for the project--for example, using Maven:
|
||||
|
||||
<!--pytest.mark.skip-->
|
||||
|
||||
```bash
|
||||
mvn package
|
||||
```
|
||||
|
||||
2. In your terminal, run the `java` command to write and query data in your bucket:
|
||||
|
||||
<!--pytest.mark.skip-->
|
||||
|
||||
```bash
|
||||
java \
|
||||
--add-opens=java.base/java.nio=org.apache.arrow.memory.core,ALL-UNNAMED \
|
||||
-jar target/PROJECT_NAME.jar
|
||||
```
|
||||
|
||||
Include the following in your command:
|
||||
|
||||
- [`--add-opens=java.base/java.nio=org.apache.arrow.memory.core,ALL-UNNAMED`](https://arrow.apache.org/docs/java/install.html#id3): with Java version 9 or later and Apache Arrow version 16 or later, exposes JDK internals for Arrow.
|
||||
For more options, see the [Apache Arrow Java install documentation](https://arrow.apache.org/docs/java/install.html).
|
||||
- `-jar target/PROJECT_NAME.jar`: your `.jar` file to run.
|
||||
|
||||
The output is the newly written data from your {{< product-name >}} bucket.
|
||||
|
||||
## Installation
|
||||
|
||||
Include `com.influxdb.influxdb3-java` in your project dependencies.
|
||||
|
||||
{{< code-tabs-wrapper >}}
|
||||
{{% code-tabs %}}
|
||||

|
||||
[Gradle dependency script](#)

## Importing the client
|
||||
|
||||
The `influxdb3-java` client library package provides
|
||||
`com.influxdb.v3.client` classes for constructing, writing, and querying data
|
||||
stored in {{< product-name >}}.
|
||||
|
||||
## API reference
|
||||
|
||||
- [Interface InfluxDBClient](#interface-influxdbclient)
|
||||
- [Initialize with credential parameters](#initialize-with-credential-parameters)
|
||||
- [InfluxDBClient instance methods](#influxdbclient-instance-methods)
|
||||
- [InfluxDBClient.writePoint](#influxdbclientwritepoint)
|
||||
- [InfluxDBClient.query](#influxdbclientquery)
|
||||
|
||||
|
||||
## InfluxDBClient interface
|
||||
|
||||
`InfluxDBClient` provides an interface for interacting with InfluxDB APIs for writing and querying data.
|
||||
|
||||
The `InfluxDBClient.getInstance` constructor initializes and returns a client instance with the following:
|
||||
|
||||
- A _write client_ configured for writing to the database.
|
||||
- An Arrow _Flight client_ configured for querying the database.
|
||||
|
||||
To initialize a client, call `getInstance` and pass your credentials as one of
|
||||
the following types:
|
||||
|
||||
- [parameters](#initialize-with-credential-parameters)
|
||||
- a [`ClientConfig`](https://github.com/InfluxCommunity/influxdb3-java/blob/main/src/main/java/com/influxdb/v3/client/config/ClientConfig.java)
|
||||
- a database connection string--for example:
|
||||
|
||||
```java
|
||||
"https://{{< influxdb/host >}}"
|
||||
+ "?token=API_TOKEN&database=DATABASE_NAME"
|
||||
```
|
||||
|
||||
### Initialize with credential parameters
|
||||
|
||||
```java
|
||||
static InfluxDBClient getInstance(@Nonnull final String host,
|
||||
@Nullable final char[] token,
|
||||
@Nullable final String database)
|
||||
```
|
||||
|
||||
- **`host`** (string): The host URL of the InfluxDB instance.
|
||||
- **`database`** (string): The bucket to use for writing and querying.
|
||||
- **`token`** (string): An API token with read/write permissions.
|
||||
|
||||
#### Example: initialize with credential parameters
|
||||
|
||||
```java
|
||||
package com.influxdata.demo;
|
||||
|
||||
import com.influxdb.v3.client.InfluxDBClient;
|
||||
import com.influxdb.v3.client.Point;
|
||||
import com.influxdb.v3.client.query.QueryOptions;
|
||||
import com.influxdb.v3.client.query.QueryType;
|
||||
|
||||
import java.time.Instant;
|
||||
import java.util.stream.Stream;
|
||||
|
||||
public class HelloInfluxDB {
|
||||
private static final String HOST_URL = "https://{{< influxdb/host >}}";
|
||||
private static final String DATABASE = "DATABASE_NAME"; // your Cloud Serverless bucket
|
||||
private static final char[] API_TOKEN = System.getenv("API_TOKEN"); // an environment variable for your Cloud Serverless API Token
|
||||
// Create a client instance, and then write and query data in InfluxDB Cloud Serverless.
|
||||
public static void main(String[] args) {
|
||||
try (InfluxDBClient client = InfluxDBClient.getInstance(HOST_URL, API_TOKEN, DATABASE)) {
|
||||
writeData(client);
|
||||
queryData(client);
|
||||
}
|
||||
catch (Exception e) {
|
||||
System.err.println("An error occurred while connecting with the serverless InfluxDB!");
|
||||
e.printStackTrace();
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
#### Default tags
|
||||
|
||||
- _Optional_: To include default
|
||||
[tags](/influxdb/cloud-serverless/reference/glossary/#tag) in all written data,
|
||||
pass a `Map` of tag keys and values.
|
||||
|
||||
```java
|
||||
InfluxDBClient getInstance(@Nonnull final String host,
|
||||
@Nullable final char[] token,
|
||||
@Nullable final String database,
|
||||
@Nullable Map<String, String> defaultTags)
|
||||
```
|
||||
|
||||
### InfluxDBClient instance methods
|
||||
|
||||
#### InfluxDBClient.writePoint
|
||||
|
||||
1. Use the `com.influxdb.v3.client.Point` class to create time series data.
|
||||
2. Call the `client.writePoint()` method to write points as line protocol in your
|
||||
bucket.
|
||||
|
||||
```java
|
||||
// Use the Point class to construct time series data.
|
||||
// Call client.writePoint to write the point in your bucket.
|
||||
private static void writeData(InfluxDBClient client) {
|
||||
Point point = Point.measurement("temperature")
|
||||
.setTag("location", "London")
|
||||
.setField("value", 30.01)
|
||||
.setTimestamp(Instant.now().minusSeconds(10));
|
||||
try {
|
||||
client.writePoint(point);
|
||||
System.out.println("Data written to the bucket.");
|
||||
}
|
||||
catch (Exception e) {
|
||||
System.err.println("Failed to write data to the bucket.");
|
||||
e.printStackTrace();
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
#### InfluxDBClient.query
|
||||
|
||||
To query data and process the results:
|
||||
|
||||
1. Call `client.query()` and provide your SQL query as a string.
|
||||
2. Use the result stream's built-in iterator to process row data.
|
||||
|
||||
```java
|
||||
// Query the latest 10 measurements using SQL
|
||||
private static void queryData(InfluxDBClient client) {
|
||||
System.out.printf("--------------------------------------------------------%n");
|
||||
System.out.printf("| %-8s | %-8s | %-30s |%n", "location", "value", "time");
|
||||
System.out.printf("--------------------------------------------------------%n");
|
||||
|
||||
String sql = "select time,location,value from temperature order by time desc limit 10";
|
||||
try (Stream<Object[]> stream = client.query(sql)) {
|
||||
stream.forEach(row -> System.out.printf("| %-8s | %-8s | %-30s |%n", row[1], row[2], row[0]));
|
||||
}
|
||||
catch (Exception e) {
|
||||
System.err.println("Failed to query data from the bucket.");
|
||||
e.printStackTrace();
|
||||
}
|
||||
}

If you deploy a licensed release of InfluxDB Clustered with an invalid or

expired license, many of the pods in your cluster will crash on startup and will

Because InfluxDB stores the license in a volume-mounted Kubernetes secret, invalid

licenses affect old and new pods.
|
||||
|
||||
Once a valid `License` resource is applied, new pods will begin to start up normally.
|
||||
Licenses are validated when the `License` resource is applied. If the license
|
||||
is invalid when you attempt to apply it, the InfluxDB clustered license
|
||||
controller will not add or update the required secret.

After you apply a valid `License` resource, new pods will begin to start up normally.

## Troubleshoot licensing
|
||||
|
||||
After you have activated licensing, use the following signals to verify licensing
|
||||
and troubleshoot issues with your {{< product-name omit="Clustered" >}}
|
||||
cluster.
|
||||
|
||||
In your commands, replace the following:

### Verify database components
|
||||
|
||||
After you [install your license](#install-your-influxdb-license),
|
||||
run the following command to check that database pods start up and are in the
|
||||
`Running` state:
|
||||
|
||||
<!--pytest.mark.skip-->
|

kubectl get pods -l app=iox --namespace NAMESPACE
|
||||
```
|
||||
|
||||
{{% /code-placeholders %}}
|
||||
|
||||
If a `Pod` fails to start, run the following command to view pod information:
|
||||
|
||||
<!--pytest.mark.skip-->
|
||||
|
||||
{{% code-placeholders "POD_NAME|NAMESPACE" %}}

kubectl describe pod POD_NAME --namespace NAMESPACE
|
||||
```
|
||||
|
||||
{{% /code-placeholders %}}
|
||||
|
||||
### Verify the `Secret` exists
|
||||
|
||||
Run the following command to verify that the licensing activation created a
|
||||
`iox-license` secret:
|
||||
|
||||
<!--pytest.mark.skip-->
|
||||
|
||||
{{% code-placeholders "NAMESPACE" %}}
|
||||
|
||||
```sh
|
||||
kubectl get secret iox-license --namespace NAMESPACE
|
||||
```
|
||||
|
||||

|
||||

|
||||

||||
The `license controller` component creates a `Secret` named `iox-license` from your
|
||||
`License`.
|
||||
|
||||
To view `license controller` logs for troubleshooting, run the following
|
