InfluxDB has introduced a new option to explicitly define the schema of data that can be written to a bucket. This feature helps protect against unwanted changes in the schema as more users add their own data. The explicit schema is specific to each measurement written to a bucket, allowing it to grow as new measurements are added. Users can create schemas for each measurement they want to store in the bucket, and any data that doesn't match one of the measurement schemas will be rejected from the bucket.
