Features

Please note that the default for file hashing (hashMode) has changed. Refer to ticket 231357 below for details.

New implementation of search and indexing (BETA - feature 234830)

With VidiCore 25.2, the index and search features based on OpenSearch are reimplemented from scratch.

Both search and indexing versions (named as “Search version 1” and “Search version 2” in the VidiCore API documentation) currently exist side by side. VidiCore can fill both indices in parallel (appropriate infrastructure assumed), so that different applications can use both search versions in parallel. A migration guide can be found in the VidiCore documentation.

The following improvements come with search version 2:

New structure of the documents in the OpenSearch index. This makes the OS indices significantly smaller and searches faster.
Restructured indexing process with less process overhead, better scaling options and partial reindexing.
Faster search queries through better internal filtering and avoiding expensive operations on OpenSearch.
More precise search results according to the query submitted to the OpenSearch API.
Direct determination of information on events found, thus avoiding a second round trip to OpenSearch.
Support of highlighting also for texts in the events.

Search version 2 can be used via a new API for the search calls itself and changes in the required search documents. Other Vidispine products are adapted to support both search versions via a configuration switch. Customers using the search API have to adapt their applications accordingly to switch to search version 2.

Search version 2 is currently in beta status. There will be improvements in future patches and releases. It cannot be ruled out that changes to the Search API and Search Document will also be necessary.

Customers should feel free to familiarize themselves with the new indexing and the new search API and provide feedback. Productive use is not recommended at this time.

Improve job handling to allow more jobs being executed in parallel (feature 234830)

Previous VidiCore versions had a limit for the execution of parallel jobs that was too low for some scenarios. VidiCore 25.2 increases this limit significantly, Vidispine internal tests show that at least a factor of 4 to 5 more jobs are possible. However, exact figures depend heavily on the specific scaling of the system and the complexity of the jobs.

Features and improvements for VSA, media operation and file state handling

One of our targets for VidiCore 25.2 is to allow the implementation of hybrid systems, where the main system runs in the cloud and services with a minimal on-premise footprint allow access to locally stored media files via the VidiCore Server Agent (VSA). To achieve this, several features and improvements are implement, which can be categorized in the following main aspects:

advanced media operations like the creation of growing media files on cloud storages, subclip creation or proxy index creation for imported proxies.
enhanced scalability by supporting resource tags for several job types.
better file state handling and detection.
general improvements for the VSA-VidiCore interoperability.
