Introduction

InfluxDB is a time-series database widely used for storing and querying time-stamped data such as monitoring metrics and logs. Integrating InfluxDB with a Spring Boot application enables developers to leverage Spring's powerful capabilities for handling time-series data. In this guide, we will explore how to perform CRUD (Create, Read, Update, Delete) operations with InfluxDB in Spring Boot.

Setting Up InfluxDB with Spring Boot

Before performing CRUD operations, it's necessary to set up InfluxDB with Spring Boot. This involves adding the required dependencies and configuring InfluxDB connection properties.

1. Add Dependencies: In the pom.xml, add dependencies for Spring Boot and InfluxDB.

2. Configure InfluxDB in application.properties:

3. Create a Configuration Class:

CRUD Operations with InfluxDB

Create: Writing Data to InfluxDB

To create or insert data into InfluxDB, you can use the write method.

In this example, we are writing a temperature measurement with the value 22.5 into the temperature measurement.

Read: Querying Data from InfluxDB

To read data, you can use the query method to execute an InfluxQL query.

Here, we query the temperature measurement for data recorded in the last hour.

Update: Modifying Data in InfluxDB

InfluxDB does not directly support updates on existing records. Instead, you need to overwrite or add new points. You can use the write method to add new points with updated values.

Delete: Removing Data from InfluxDB

To delete data from InfluxDB, use the query method to execute a DELETE statement.

In this case, we delete all records in the temperature measurement where the value is 22.5.

Practical Example

Conclusion

Performing CRUD operations with InfluxDB in Spring Boot involves setting up the InfluxDB configuration, using the InfluxDB object to write, query, update, and delete time-series data. Although InfluxDB does not support direct update operations, new points with updated values can be written. By integrating InfluxDB into your Spring Boot application, you can efficiently handle time-series data for your use cases.
