Identifying Files
Learn how Kafka Connect FilePulse uniquely identifies files.
Kafka Connect FilePulse uses a pluggable interface called SourceOffsetPolicy for
uniquely identifying files. Basically, the implementation passed in the connector’s configuration is used for computing a unique identifier which is
used by Kafka Connect to persist the position of the connector for each file (i.e., the offsets saved in the connect-offsets topic).
By default, Kafka Connect FilePulse use the default implementation DefaultSourceOffsetPolicy which accepts the following configuration:
| Configuration | Description | Type | Default | Importance |
|---|---|---|---|---|
offset.attributes.string | A separated list of attributes, using ‘+’ character as separator, to be used for uniquely identifying an object file; must be one of [name, path, lastModified, inode, hash, uri] (e.g: name+hash). Note that order doesn’t matter. | string | path+name | HIGH |
