ArangoSearch
| Issue |
|---|
| Date Added: 2018-12-03 Component: ArangoSearch Deployment Mode: Cluster Description: Score values evaluated by corresponding score functions (BM25/TFIDF) may differ in single-server and cluster with a collection having more than 1 shard Affected Versions: 3.4.x, 3.5.x Fixed in Versions: - Reference: arangodb/backlog#508 (internal) |
| Date Added: 2018-12-03 Component: ArangoSearch Deployment Mode: Cluster Description: ArangoSearch index consolidation does not work during creation of a link on existing collection which may lead to massive file descriptors consumption Affected Versions: 3.4.x, 3.5.x Fixed in Versions: 3.6.0 Reference: arangodb/backlog#509 (internal) |
| Date Added: 2018-12-03 Component: ArangoSearch Deployment Mode: Cluster Description: Long-running DML transactions on collections (linked with ArangoSearch view) block “ArangoDB flush thread” making impossible to refresh data “visible” by a view Affected Versions: 3.4.x Fixed in Versions: 3.5.0 Reference: arangodb/backlog#510 (internal) |
| Date Added: 2018-12-03 Component: ArangoSearch Deployment Mode: All Description: RocksDB recovery fails sometimes after renaming a view Affected Versions: 3.4.x Fixed in Versions: 3.5.0 Reference: arangodb/backlog#469 (internal) |
| Date Added: 2018-12-03 Component: ArangoSearch Deployment Mode: All Description: Using a loop variable in expressions within a corresponding SEARCH condition is not supported Affected Versions: 3.4.x, 3.5.x Fixed in Versions: - Reference: arangodb/backlog#318 (internal) |
| Date Added: 2018-12-03 Component: ArangoSearch Deployment Mode: All Description: Using score functions (BM25/TFIDF) in ArangoDB expression is not supported Affected Versions: 3.4.x Fixed in Versions: 3.5.0 Reference: arangodb/backlog#316 (internal) |
| Date Added: 2019-05-16 Component: ArangoSearch Deployment Mode: All Description: You may experience server slowdowns caused by Views. Removing a collection link from the view configuration mitigates the problem. Affected Versions: 3.4.x, 3.5.x Fixed in Versions: - Reference: N/A |
| Date Added: 2019-05-28 Component: ArangoSearch Deployment Mode: All Description: For specific input data indexed by ArangoSearch and used via views functionality a crash can occur during lookup (AQL query execution) in the internal index structure. This issue affects only view-related AQL queries with the SEARCH keyword involved. Please upgrade to ArangoDB v3.4.6 (or newer) which contains a fix for the ArangoSearch implementation and reindex views by recreating them (drop and create with the same parameters). Affected Versions: 3.4.x Fixed in Versions: 3.4.6 Reference: N/A |
AQL
| Issue |
|---|
| Date Added: 2018-09-05 Component: AQL Deployment Mode: Cluster Description: In a very uncommon edge case there is an issue with an optimization rule in the cluster. If you are running a cluster and use a custom shard key on a collection (default is _key) and you provide a wrong shard key in a modifying query (UPDATE, REPLACE, DELETE) and the wrong shard key is on a different shard than the correct one, a DOCUMENT NOT FOUND error is returned instead of a modification (example query: UPDATE { _key: "123", shardKey: "wrongKey"} WITH { foo: "bar" } IN mycollection). Note that the modification always happens if the rule is switched off, so the suggested workaround is to deactivate the optimizing rule restrict-to-single-shard. Affected Versions: 3.4.x, 3.5.x Fixed in Versions: - Reference: arangodb/arangodb#6399 |
Upgrading
| Issue |
|---|
| Date Added: 2019-05-16 Component: arangod Deployment Mode: All Description: Upgrading from 3.4.4 to 3.4.x under CentOS using rpm -U or yum upgrade is unable to succeed because of a problem with the package. The arangodb3 service will not be available anymore. Uninstalling with rpm -e or yum remove may fail or not clean up all of the folders. Affected Versions: >= 3.4.4 Fixed in Versions: 3.4.8, 3.5.0 (upgrading works from these versions on again) Reference: arangodb/release-qa#50 (internal) |
| Date Added: 2019-05-16 Component: arangod Deployment Mode: All Description: Major upgrades such as 3.3.22 to 3.4.5 fail to upgrade the database directory under CentOS. The server log suggests to use the script /etc/init.d/arangodb but it is not available under CentOS. Workaround: Add database.auto-upgrade = true to /etc/arangodb3/arangod.conf, restart the service, remove database.auto-upgrade = true from the configuration and restart the service once more. Affected Versions: 3.4.x (CentOS only) Fixed in Versions: 3.4.8 Reference: arangodb/release-qa#50 (internal) |
| Date Added: 2019-05-16 Component: arangod Deployment Mode: All Description: Bugfix release upgrades such as 3.4.4 to 3.4.5 may not create a backup of the database directory even if they should.

| Date Added: 2019-11-06 Component: arangod Deployment Mode: All Description: Upgrades from ArangoDB version 3.4.x to 3.5.0 or 3.5.1 don’t create the _analyzers system collection, preventing creation and use of custom Analyzers.Suggested workaround: Create the missing collection manually in each database of an ArangoDB deployment after upgrade (arangosh example: db._create("_analyzers", {isSystem: true})) Affected Versions: 3.5.0, 3.5.1 Fixed in Versions: 3.5.2 Reference: arangodb/backlog#652 (internal) |
| Date Added: 2019-12-10 Component: Installer Deployment Mode: All Description: The NSIS installer for Windows may fail to upgrade an existing installation, e.g. from 3.4.a to 3.4.b (patch release), with the error message: “failed to detect whether we need to Upgrade” Affected Versions: 3.4.x Fixed in Versions: - Reference: arangodb/release-qa#183 (internal) |

|---|
| Date Added: 2018-12-04 Component: arangod Deployment Mode: All Description: Parallel creation of collections using multiple client connections with the same database user may spuriously fail with “Could not update user due to conflict” warnings when setting user permissions on the new collections.

| Date Added: 2019-02-18 Component: arangod Deployment Mode: All Description: There is a clock overflow bug within Facebook’s RocksDB storage engine for Windows.

An immediate workaround is to change the server configuration: [rocksdb]throttle = false Affected Versions: 3.x.x (Windows only) Fixed in Versions: 3.3.23, 3.4.4 Reference: facebook/rocksdb#4983 |
| Date Added: 2019-03-13 Component: arangod Deployment Mode: Active Failover Description: A full resync is triggered after a failover, when the former leader instance is brought back online.

| Date Added: 2020-01-07 Component: Installer Deployment Mode: All Description: V8-based binaries of the client packages (arangosh, arangoinspect, foxx-manager) have an incorrect default value for javascript.startup-directory and will thus not find the required JavaScript folder unless specified by the user. Affected Versions: 3.4.x, 3.5.x, 3.6.0 Fixed in Versions: 3.4.9, 3.5.4, 3.6.1 Reference: arangodb/release-qa#183 (internal) |

| Date Added: 2020-06-19 Component: SmartGraphs Deployment Mode: Cluster Description: When inserting edges into an edge collection of a SmartGraph, the auto-generated _rev values for the ingoing and outgoing part of the edge may differ.
