InfluxDB is a powerful time-series database designed to handle high write and query loads. It is optimized for time-stamped data, making it ideal for use cases such as monitoring, IoT, and real-time analytics. InfluxDB allows you to store and query data efficiently, providing a robust platform for time-series data management.
When working with InfluxDB, you might encounter the error message ERR: field type conflict. This error typically occurs when there is an attempt to write data to a field in a measurement with a data type that differs from the one previously used. This inconsistency can disrupt data integrity and lead to unexpected behavior in your database operations.
The ERR: field type conflict error arises because InfluxDB enforces strict data typing for fields within a measurement. Once a field is created with a specific data type, all subsequent writes to that field must match the original data type. For example, if a field is initially written as an integer, any attempt to write a string or float to that field will trigger this error.
To resolve the ERR: field type conflict error, follow these steps:
First, determine which field is causing the conflict. You can do this by examining the error message and identifying the measurement and field name involved. Use the following query to inspect the schema of the measurement:
SHOW FIELD KEYS FROM "your_measurement_name"
Once you have identified the conflicting field, ensure that all data written to this field is of the same type. Review your data ingestion process and application logic to confirm that the data type remains consistent.
If you find that the data type needs to be changed, consider the following approaches:

By following these steps and ensuring consistent data types, you can effectively resolve the ERR: field type conflict error and maintain the integrity of your InfluxDB data.
