LTS 2021.12 / LTS 2021-HF12

What's New in LTS 2021.12 / LTS 2021-HF12

Nuxeo Server

Tomcat 9.0.55

The Nuxeo Platform now relies on Tomcat 9.0.55.

Keep the Platform Fully Available While Performing a Re-Indexing With Alias

It is now possible to perform a full reindexing of the repository without any interruption of service. This will work in the following case:

Nuxeo is configured to manage elastic aliases: elasticsearch.manageAlias.enabled=true.
Reindexing is done using the Bulk Service see NXP-26032 (the WorkManager legacy reindexing behavior triggered by the admin UI is unchanged).

The repository is reindexed into a new index, all update operations are propagated to the existing and new indexes, when the repository indexing is completed aliases are updated, and the old index can be manually deleted.

It is possible to scale up Nuxeo nodes during reindexing (and to scale down once the bulk scroller is completed).

Note that you need to ensure you have enough elastic disk space first.

Enable to Set Bulk Query Limit From PP Rest Invokation

A query limit can be enforced from Page Provider REST invokation.

Major Bug Fixes

Read ACL for All Versions of Children Are Recomputed After a Permission Change

During an ACL update of a folder, Read ACL are materialized on children documents for search optimization, this is done on different backends (Mongo, PostgreSQL).

The current fix is also recomputing Read ACL for all versions of children, this means more queries and database updates, which certainly impacts the performance during massive ACL updates.

Fix blobProviderId Still Present When Moving Blob From a S3 Blob Provider to Another S3 Blob Provider

Better management of the blob ProviderId when moving blob from a S3 blob provider to another S3 blob provider.

Fix operation Repository.Query When Parameter 'searchTerm' is Provided with an Empty String

The operation Repository.Query handles the parameter searchTerm set to an empty string.
