+
+InfluxDB3Source extracts data from a specified set of measurements in a
+  database (or all available ones if none are specified).
+
+It processes measurements sequentially by gathering/producing a tumbling
+  "time_delta"-sized window of data, starting from 'start_date' and eventually
+  stopping at 'end_date', completing that measurement.
+
+It then starts the next measurement, continuing until all are complete.
+
+If no 'end_date' is provided, it will run indefinitely for a single
+  measurement (which means no other measurements will be processed!).

+***Arguments:***
+
+- `host`: Host URL of the InfluxDB instance.
+- `token`: Authentication token for InfluxDB.
+- `organization_id`: Organization name in InfluxDB.
+- `database`: Database name in InfluxDB.
+- `key_setter`: sets the kafka message key for a measurement record.
+By default, will set the key to the measurement's name.
+- `timestamp_setter`: sets the kafka message timestamp for a measurement record.
+By default, the timestamp will be the Kafka default (Kafka produce time).
+- `start_date`: The start datetime for querying InfluxDB. Uses current time by default.
+- `end_date`: The end datetime for querying InfluxDB.
+If none provided, runs indefinitely for a single measurement.
+- `measurements`: The measurements to query. If None, all measurements will be processed.
+- `measurement_column_name`: The column name used for appending the measurement name to the record.
+- `sql_query`: Custom SQL query for retrieving data.
+Query expects a `{start_time}`, `{end_time}`, and `{measurement_name}` for later formatting.
+If provided, it overrides the default window-query logic.
+- `time_delta`: Time interval for batching queries, e.g., "5m" for 5 minutes.
+- `delay`: An optional delay between producing batches.
+- `name`: A unique name for the Source, used as part of the topic name.
+- `shutdown_timeout`: Time in seconds to wait for graceful shutdown.
+- `max_retries`: Maximum number of retries for querying or producing.
+Note that consecutive retries have a multiplicative backoff.
+- `on_client_connect_success`: An optional callback made after successful
+client authentication, primarily for additional logging.
+- `on_client_connect_failure`: An optional callback made after failed
+client authentication (which should raise an Exception).
+Callback should accept the raised Exception as an argument.
+Callback must resolve (or propagate/re-raise) the Exception.
