-------------------------------------------
Summary: Redesign the remove duplicates function for adapters
Key: STREAMPIPES-582
URL: https://issues.apache.org/jira/browse/STREAMPIPES-582
Project: StreamPipes
Issue Type: Improvement
Components: Connect
Reporter: Philipp Zehnder
Fix For: 0.90.0
h2. Current functionality
A user can select the *remove duplicate* option in the start adapter tab and
select the *time interval* how long events are stored in cache (class:
{{{}org.apache.streampipes.connect.adapter.preprocessing.transform.stream.DuplicateFilterPipelineElement{}}})
h3. Problems
* The state is not persisted when an adapter is restarted
* No option to ignore the timestamp field
h3. New functionality
* A user should be able to add the remove duplicate rule with the option to
ignore the timestamp field.
* A user should be able to restart an adapter without loosing the state of the
remove duplicate rule
h3. Info
* To do that we need to extend the API of adapters and add the functionality
to execute code when an adapter is stopped
* An API to load data (on startup) and persist (on shutdown) for elements is
required
