v2.8.0-alpha

What's Changed

Features

New fragmentation strategy is added: reference fragmentation

In the previous release, multiple member types support was added. This came with the need to fragmentise by this member type. To provide this, a new fragmentation strategy is added, which makes it possible to fragmentise upon objects of the LDES, including the member type. This is added in #1112 and #1123

DCAT validity in health endpoint

To reflect the state of the configured DCAT metadata validity, this has been included in the health endpoint of the server in #1126

Split the ports of the fetch, admin and ingest API's

API's can be secured individually by providing the option to expose the API's on different ports in #1129

Increase robustness of the admin API to create LDESes and views

Some issues were experienced while creating event streams and views:

• it was possible to create more than one retention policy of the same type (e.g. ldes:DurationAgoPolicy of 1 year and 9 months), this has been fixed in #1127
• when an event stream was created, but an issue occurred while saving the shacl shape or views, a 400 response was sent, but the event stream was created without the views and/or shape, which was not transparent to the end user. This has been solved in #1130

Fixes

The view validation still validated for the deprecated tree:TimeBasedFragmentation

The viewShaclShape.ttl, which is used to validate views created by the admin, still contained the deprecated tree:TimeBasedFragmentation instead of the new tree:HierarchicalTimeBasedFragmentation, this has been fixed in #1083 and #1097

Observability issues in MemberConverter

Some issues were detected in the MemberConverter with the @Observed annotation, due to its extension of an abstract class with final methods. Now an interface is used instead of this abstract class in #1121

Duplicate member ingestion improvements

Some improvements are implemented when a duplicate member is ingested in #1110. These improvements include:

• The logging message includes more details and the logging level is set to WARN
• A 200 response is sent instead of a 201 when a duplicate member is ingested

Member id extraction issue

Since the previous release, the member extraction is happening via the versionOfPath. However, a hard coded value was used instead of the versionOfPath of the event stream. This has been fixed in #1132

No Content-Type header was provided in the Responses

When content was provided in the response body, no Content-Type was provided in the headers. This has been fixed in #1133

Documentation

• Suggestion to improve GitHub pages are implemented in #1081
• Page fragmentation name is removed from docs in #1098
• Target class is removed from API docs in #1111
• The duplicate member ingestion documentation is made more clear in #1114
• The deprecated point-in-time retention policy is removed from the documentation in #1128

Documentation

Mongo connection URI documentation has been updated in #1042

We received a contribution by @MPParsley, where the documentation for the Mongo connection URI has been updated, and now provides more information how to set up this URI with authentication

Documentation for relative URI's has been added in #1055

In the previous release, we added support for usage of relative URI's. Documentation for this feature has now been added

Features

Check for incompatible RDF types when using relative URI's has been added in #1054

In the previous release, we added support for usage of relative URI's. However, some RDF types do not support relative URI's, and therefor, a check is now added before parsing the RDF with relative URI's

Reliability & Code Quality

Flaky integration tests fixed in #1046

Some integration tests were flaky and this issue is now resolved

Code smells fixed in #1046

We encountered some code smells, but these are now fixed

Removed deprecated code in #1048

Both substring fragmentation and snapshotting were deprecated and are now completely removed

Package size reduced in #1052

In the Docker file, we now added the --no-cache flag to reduce package size

Methods in the fetching controllers are cleaned up in #1053

In the fetching module, both the TreeNodeController as EventstreamController had ResponseEntity<> as return type and used HttpServletResponse to gain control over the HTTP response. Now the HttpServletResponse is removed and only the ResponseEntity is used to control the response.

Features

Dependencies

• build(deps-dev): bump de.flapdoodle.embed:de.flapdoodle.embed.mongo.spring30x from 4.9.3 to 4.11.0 in #1000
• build(deps): bump org.junit.platform:junit-platform-suite from 1.10.0 to 1.10.1 in #974

• build(deps): bump net.bytebuddy:byte-buddy from 1.14.9 to 1.14.10 in #1005

Performance improvements

Optimise Ldes Member Ingestion in #1004

We directly insert new members instead of doing a save which first did a fetch to check if we required an insert or an update.

Use database to determine members ready for deletion in retention in #1007

We moved the logic to determine if members should be deleted or not from java code to a mongo query. We no longer need to read the entire database to java when we want to retire members.

Disable remaining members due to performance issues in #1028 in #1030

We disabled the property indicating how many members there are in a view as this required too much resources on large databases. This will be returned in future releases with better performance.

Features

Support non-default servlet context path in #1013

Support for the spring property server.servlet.context-path was added

Pyroscope support #1031

This makes it possible to do an in depth analysis of how requests are processed internally.

Relative url support in #1034

The server now supports relative url's. This needs to be activated by setting the new property ldes-server.use-relative-url on true.

Improved metrics and logging in #1025 and #1023

Documentation

Update README.md in #1022
