Recent Releases
3.3.1129 Jun 2018 15:05
minor feature:
Upgraded arangosync version to 0.5.3.
Upgraded arangodb starter version to 0.12.0.
Internal : quot;unexpected document key quot; error when custom.
Shard keys are used and the quot;allowUserKeys quot; key generator option is set
to false.
AQL DOCUMENT lookup function for documents for sharded collections with.
More than a single shard and using a custom shard key (i.e. some shard
Key attribute other than `_key`).
The previous implementation of DOCUMENT restricted to lookup to a single.
Shard in all cases, though this restriction was invalid. That lead to
`DOCUMENT` not finding documents in cases the wrong shard was contacted. The.
Implementation in 3.3.11 will reach out to all shards to find the
Document, meaning it will produce the correct result, but will cause more
Cluster-internal traffic. This increase in traffic may be high if the number
of shards is also high, because each invocation of `DOCUMENT` will have to.
Contact all shards.
There will be no performance difference for non-sharded collections or.
Collections that are sharded by `_key` or that only have a single shard.
Reimplemented replication view in web UI.
Internal : ui, document id not showing up when deleting a document.
Internal : wrong labels within foxx validation of service.
Input parameters
Internal : misplaced tooltips in indices view.
Added new arangoinspect client tool, to help users and customers easily collect.
Information of any ArangoDB server setup, and facilitate troubleshooting for the
ArangoDB Support Team.
3.3.1007 Jun 2018 14:25
minor bugfix:
Make optimizer rule "remove-filter-covered-by-index" not stop after removing
a sub-condition from a FILTER statement, but pass the optimized FILTER.
Statement again into the optimizer rule for further optimizations.
This allows optimizing away some more FILTER conditions than before.
Allow accessing /_admin/status URL on followers too in active failover setup.
Cluster COLLECT optimization for attributes that were in "sorted" variant of
COLLECT and that were provided by a sorted index on the collected attribute.
Apply fulltext index optimization rule for multiple fulltext searches in.
The same query
This https://stackoverflow.com/questions/50496274/two-fulltext-searches-on-arangodb-cluster-v8-is-involved.
Validate `_from` and `_to` values of edges on updates consistently.
: Unexpected AQL Result.
: Frequent 'updated local foxx repository' messages.
: Empty result if FULLTEXT() is used together with LIMIT offset.
: a vulnerability within the web ui's index view.
Inception was ignoring leader's configuration.
3.3.923 May 2018 04:05
minor documentation:
Added `/_admin/repair/distributeShardsLike` that repairs collections with.
DistributeShardsLike where the shards aren't actually distributed like in the
Prototype collection, as could happen due to internal Foxx queues when queues are created in a request handler with an
ArangoDB authentication header.
Upgraded arangosync version to 0.5.1.
Upgraded arangodb starter version to 0.11.3.
Cluster upgrading introduced in 3.3.8.
The made arangod crash when starting a DB server with option.
`--database.auto-upgrade true`.
C++ implementation of AQL ZIP function to return each distinct attribute.
Name only once. The previous implementation added non-unique attribute names
Multiple times, which led to follow-up.
Now if an attribute name occurs multiple times in the input list of attribute.
Names, it will only be incorporated once into the result object, with the
Value that corresponds to the first occurrence.
This also changes the V8 implementation of the ZIP function, which now.
Will always return the first value for non-unique attribute names and not the
Last occurring value.
Self heal during a Foxx service install, upgrade or replace no longer breaks.
The respective operation
Make /_api/index, /_api/database and /_api/user REST handlers use the scheduler's.
Internal queue, so they do not run in an I/O handling thread
: C++ implementation of LIKE function now matches the old and.
Correct behavior of the JavaScript implementation.
Added REST API endpoint /_admin/server/availability for monitoring purposes.
UI: an unreasonable event within the modal view engine.
: gharial api is now checking existence of _from and _to vertices.
During edge creation
Internal : number of documents in the UI is not adjusted after.
Moving them
Internal : UI - loading a saved query does not update the list
of bind parameters.
Internal database filter in UI.
: Wrong used GeoIndex depending on FILTER order.
Added `query` and `aql.literal` helpers to `@arangodb` mod
3.2.1517 May 2018 09:05

During edge creation
3.3.828 Apr 2018 03:15
minor bugfix:
Added arangod startup option `--dump-options` to print all configuration parameters
as a JSON object.
: (Enterprise only) If you restore a SmartGraph where the collections.
Are still existing and are supposed to be dropped on restore we ended up in
Duplicate name error. This is now gone and the SmartGraph is correctly restored.
Lookups by `_id` in smart graph edge collections.
Improve startup resilience in case there are datafile errors (MMFiles).
Also allow repairing broken VERSION files automatically on startup by.
Specifying the option `--database.ignore-datafile-errors true`
: UI query editor now supports usage of empty string as bind parameter value.
Internal : Number of documents found by filter is misleading in web UI.
Added startup option `--database.required-directory-state`.
Using this option it is possible to require the database directory to be
in a specific state on startup. the options for this value are:
Non-existing: database directory must not exist.
Existing: database directory must exist.
Empty: database directory must exist but be empty.
Populated: database directory must exist and contain specific files already.
Any: any state allowed.
Field " schema" in Foxx manifest.json files no longer produce warnings.
Added `@arangodb/locals` module to expose the Foxx service context as an.
Alternative to using `module.context` directly.
Supervision can be put into maintenance mode.
3.2.1424 Apr 2018 06:45
minor feature:

3.3.713 Apr 2018 03:15
minor bugfix:
Added hidden option `--query.registry-ttl` to control the lifetime of cluster AQL.
Query parts
Internal : AQL queries on collections with replicationFactor:
"satellite" crashed arangod in single server mode.
Restore of satellite collections: replicationFactor was set to 1 during.
Restore
Dump and restore of smart graphs:
a) The dump will not include the hidden shadow collections anymore, they were dumped.
Accidentially and only contain duplicated data.
b) Restore will now ignore hidden shadow collections as all data is contained
in the smart-edge collection. You can manually include these collections from an.
Old dump (3.3.5 or earlier) by using `--force`.
c) Restore of a smart-graph will now create smart collections properly instead
of getting into `TIMEOUT_IN_CLUSTER_OPERATION`.
in AQL query optimizer rule "restrict-to-single-shard", which.
May have sent documents to a wrong shard in AQL INSERT queries that specified
The value for `_key` using an expression (and not a constant value)
Important: if you were affected by this in v3.3.5 it is required that you.
Recreate your dataset in v3.3.6 (i.e. dumping and restoring) instead of doing
a simple binary upgrade.
Added /_admin/status HTTP API for deging purposes.
Added ArangoShell helper function for packaging all information about an
AQL query so it can be run and analyzed elsewhere:
Query = "FOR doc IN mycollection FILTER doc.value 42 RETURN doc";.
Require("@arangodb/aql/explainer").deDump("/tmp/query-de-info", query);
Entitled users can send the generated file to the ArangoDB support to facilitate.
Reproduction and deging.
Added hidden option `--server.ask-jwt-secret`. This is an internal option.
For deging and should not be exposed to end-users.
For internal. supervision will now wait for agent to.
Fully prepare before adding 10 second grace period after leadership change
Internal 's FailedLeader timeout.

minor bugfix:
: Wrong used GeoIndex depending on FILTER order.
Make build id appear in startup log message alongside with other version info.
Make AQL data modification operations that are sent to all shards and that are.
Supposed to return values (i.e. `RETURN OLD` or `RETURN NEW`) not return fake
Empty result rows if the document to be updated/replaced/removed was not present
on the target shard.
Added AQL optimizer rule `restrict-to-single-shard`.
This rule will kick in if a collection operation (index lookup or data.
Modification operation) will only affect a single shard, and the operation can be
Restricted to the single shard and is not applied for all shards. This optimization
Can be applied for queries that access a collection only once in the query, and that
do not use traversals, shortest path queries and that do not access collection data.
Dynamically using the `DOCUMENT`, `FULLTEXT`, `NEAR` or `WITHIN` AQL functions.
Additionally, the optimizer will only pull off this optimization if can safely.
Determine the values of all the collection's shard keys from the query, and when the
Shard keys are covered by a single index (this is always true if the shard key is
The default `_key`)
Display missing attributes of GatherNodes in AQL explain output.
Make AQL optimizer rule `undistribute-remove-after-enum-coll` fire in a few.
More cases in which it is possible
Slightly improve index selection for the RocksDB engine when there are multiple.
Competing indexes with the same attribute pre, but different amount of
Attributes covered. In this case, the more specialized index will be preferred
Now
: removeFollower now prefers to remove the last follower(s).
Added "collect-in-cluster" optimizer rule to have COLLECT WITH COUNT queries.
Without grouping being executed on the DB servers and the coordinator only summing
up the counts from the individual shards.
: Nested FOR query uses index but ignores other filters.
Properly exit v8::Context in one place where i

a where supervision tried to deal with shards of virtual collections.
Behaviour of permissions for databases and collections changed:
The new fallback rule for databases for which an access level is not explicitly specified:
Choose the higher access level of:
A wildcard database grant.
A database grant on the `_system` database
The new fallback rule for collections for which an access level is not explicitly specified:
Choose the higher access level of:
Any wildcard access grant in the same database, or on "*/*".
The access level for the current database.
The access level for the `_system` database.
Internal : collection creation using distributeShardsLike yields.
Errors and did not distribute shards correctly in the following cases:
1. If numberOfShards replicationFactor nrDBServers != 0.
(shards replication is not divisible by DBServers).
2. If there was failover / move shard case on the leading collection.
And creating the follower collection afterwards.
Timeout in replication client expiration.
Added missing edge filter to neighbors-only traversals
in case a filter condition was moved into the traverser and the traversal was.

The procedure for determining the actual maximum value of V8 contexts is unchanged
Apart from the value `16` and works as follows:
if explicitly set, the value of the configuration option `--javascript.v8-contexts`
is used as the maximum number of V8 contexts.
When the option is not set, the maximum number of V8 contexts is determined
by the configuration option `--server.threads` if that option is set. if.

Spurious cluster hangups by always sending AQL-query related requests
to the correct servers, even after failover or when a follower drops.
The problem with the previous shard-based approach was that responsibilities.
For shards may change from one server to another at runtime, after the query
Was already instanciated. The coordinator and other parts of the query then
Sent further requests for the query to the servers now responsible for the
Shards.
However, an AQL query must send all further requests to the same servers on.
Which the query was originally instanciated, even in case of failover.
Otherwise this would potentially send requests to servers that do not know.
About the query, and would also send query shutdown requests to the wrong
Servers, leading to abandoned queries piling up and using resources until
They automatically time out.
With RocksDB engine acquiring the collection count values too.
Early, leading to the collection count values potentially being slightly off
Even in exclusive transactions (for which the exclusive access should provide
an always-correct count value).
Some in leader-follower catch-up code, specifically for the
RocksDB engine.
Make V8 log fatal errors to syslog before it terminates the process.
This change is effective on Linux only.
With MMFiles engine creating superfluous collection journals

When a single AQL query reaches the specified limit value, the query will be.
Aborted with a *resource limit exceeded exception. In a cluster, the memory
Accounting is done per shard, so the limit value is effectively a memory limit per
Query per shard.
The global limit value can be overriden per query by setting the *memoryLimit*.

Parameter to a string parameter with the following possible values:
- "fail":
Will validate _rev values of 3.0 collections on collection loading and throw an exception when invalid _rev values are found.
in this case collections with invalid _rev values are marked as corrupted and cannot be used in the ArangoDB 3.1 instance.
The procedure for such collections is to export the collections from 3.0 database with arangodump and restore them in 3.1 with arangorestore.
Collections that do not contain invalid _rev values are marked as ok and will not be re-checked on following loads.
Collections that contain invalid _rev values will be re-checked on following loads.
- "true":
Will validate _rev values of 3.0 collections on collection loading and print a warning when invalid _rev values are found.
in this case collections with invalid _rev values can be used in the ArangoDB 3.1 instance.
However, subsequent operations on documents with invalid _rev values may silently fail or fail with explicit errors.
The procedure for such collections is to export the collections from 3.0 database with arangodump and restore them in 3.1 with arangorestore.
Collections that do not contain invalid _rev values are marked as ok and will not be re-checked on following loads.
