Bug fixes and updates

Advance Warning

The following items are due to change in a future release.

  • Security

    • Starting from LogScale version 1.237, support for insecure ldap connections will be removed. Self-Hosted customers using LDAP will only be able to use ldaps secure connections.

Deprecation

Items that have been deprecated and may be removed in a future release.

  • rdns() has been deprecated and will be removed in version 1.249. Use reverseDns() as an alternative function.

  • The Secondary Storage feature is now deprecated and will be removed in LogScale 1.231.0.

    The Bucket Storage feature provides superior functionality for storing rarely queried data in cheaper storage while keeping frequently queried data in hot storage (fast and expensive). For more information, see Bucket Storage.

    Please contact LogScale support for any concerns about this deprecation.

Behavior Changes

Scripts or environment which make use of these tools should be checked and updated for the new configuration:

  • Storage

    • Revised bucket transfer priority to the following, in descending order:

      1. Segment uploads transferred to bucket storage for replication

      2. Lookup file uploads transferred to bucket storage for replication

      3. Downloads of minisegments for queries

      4. Downloads of other segments for queries

      5. Segment uploads for disaster recovery migration

      6. Segment downloads for background operations

Upgrades

Changes that may occur or be required during an upgrade.

  • Installation and Deployment

    • Upgraded LogScale's bundled Java Development Kit (JDK) to version 25.0.2, resolving the Transparent Huge Pages (THP) issue mentioned in release 1.213.0 (see RN Issue), where systems configured with THP mode as madvise did not enable huge pages when running with the default garbage collector.

Fixed in this release

  • Storage

    • Fixed an issue with task cancellation in the node-to-node segment fetcher that could cause a terminating node to drop a copy of the segment file it was fetching.

    • Fixed an issue where nodes could enter a repeated download and deletion loop of the same segment due to over-replication.

Known Issues

  • Storage

    • For clusters using secondary storage where the primary storage on some nodes in the cluster may be getting filled (i.e. the storage usage on the primary disk is halfway between PRIMARY_STORAGE_PERCENTAGE and PRIMARY_STORAGE_MAX_FILL_PERCENTAGE), those nodes may fail to transfer segments from other nodes. The failure will be indicated by the error java.nio.file.AtomicMoveNotSupportedException with message "Invalid cross-device link".

      This does not corrupt data or cause data loss, but will prevent the cluster from being fully healthy, and could also prevent data from reaching adequate replication.

Improvement

  • Queries

    • Optimized performance for Regular Expression Engine v2 regarding zero-or-more repetitions of single character regex matches at the start of regexes. For example, regexes such as /.*foo/ now complete more quickly, also compared to the previous engine.
