InfluxDB is a time-series database designed to handle high write and query loads. It's optimized for time-stamped data, making it ideal for use cases like monitoring, IoT, and real-time analytics. With its powerful query language and efficient storage engine, InfluxDB allows users to store, query, and analyze time-series data with ease.
When working with InfluxDB, you might encounter the error message ERR: invalid timestamp. This error typically appears when attempting to write data points with a timestamp that InfluxDB cannot process. This can disrupt data ingestion and lead to incomplete datasets.
The error ERR: invalid timestamp indicates that the timestamp provided in your data point is either not in a valid format or falls outside the acceptable range. InfluxDB requires timestamps to be in nanoseconds since the Unix epoch (January 1, 1970). If the timestamp is not correctly formatted or is too far in the past or future, InfluxDB will reject the data point.
To resolve the ERR: invalid timestamp issue, follow these steps:
Ensure that your timestamps are in nanoseconds since the Unix epoch. You can convert timestamps from other units (e.g., seconds, milliseconds) to nanoseconds by multiplying them appropriately. For example, to convert seconds to nanoseconds, multiply by 1,000,000,000.
timestamp_in_seconds = 1633072800
timestamp_in_nanoseconds = timestamp_in_seconds * 1000000000
Verify that your timestamps are within a reasonable range. InfluxDB typically handles timestamps from 1677-09-21 to 2262-04-11. Ensure your timestamps fall within this range to avoid errors.
Ensure that your timestamp values are of the correct data type. In most programming languages, this means using an integer data type that can handle large numbers, such as int64 in Go or long in Java.
Before ingesting large datasets, test your data ingestion process with a small sample to ensure that timestamps are correctly formatted and within range. This can help identify issues early and prevent large-scale data rejection.
