Use change data capture to stream files from AWS S3 buckets to any data sink and transform them on the way.
At startup, the connector extracts data from all (matching) files from the given folder. After this initial sync, it watches the folder for new files and syncs only relevant changes.
Please provide a pair of AWS access key ID and AWS secret access key, which has the permissions to list your buckets (
s3:ListBucket) and retrieve objects (
This source connector supports the following configuration options:
Your AWS region (default:
AWS access key ID
The AWS access key ID to use for authentication.
AWS secret access key
The AWS secret access key to use for authentication
The name of the AWS S3 bucket from which we shall extract files.
File name filter
Regular expression applied to files from the AWS S3 bucket. Only files with a name matching the regular expression will be extracted. Default value:
.*(matches all file names).
The format of the extracted files. At the moment, this connector only supports CSV and Parquet files.
CSV delimiter value
Only available for the file type CSV. The character that delimits different columns (default:
Generate attribute names from CSV header row
Only available for the file type CSV. Whether to use the first row of the CSV file for extracting attribute names or not. If this option is set to false, DataCater will generate attribute names based on the index of the attribute, and name them
Primary key column
Name of the attribute that uniquely identifies records, similar to a primary key in a database system.
Sync interval (s)
The interval in seconds between the synchronization of the AWS S3 bucket and DataCater (default:
120). When synchronizing, DataCater consumes only those files from the AWS S3 bucket, which have not yet been processed by the pipeline, allowing to implement change data capture to some degree.
DataCater automatically extends the set of attributes with the attribute
__datacater_file_nameand fills it with the name of the file.
