ArangoDB v3.11 is under development and not released yet.

This documentation is not final and potentially incomplete.

Incompatible changes in ArangoDB 3.11

It is recommended to check the following list of incompatible changes before upgrading to ArangoDB 3.11, and adjust any client programs if necessary.

The following incompatible changes have been made in ArangoDB 3.11:

Restriction of indexable fields

It is now forbidden to create indexes that cover fields whose attribute names start or end with : , for example, fields: ["value:"]. This notation is reserved for internal use.

Existing indexes are not affected but you cannot create new indexes with a preceding or trailing colon.

Startup options

--server.disable-authentication and --server.disable-authentication-unix-sockets obsoleted

The --server.disable-authentication and --server.disable-authentication-unix-sockets startup options are now obsolete. Specifying them is still tolerated but has no effect anymore. These options were deprecated in v3.0 and mapped to --server.authentication and --server.authentication-unix-sockets, which made them do the opposite of what their names suggest.

--database.force-sync-properties deprecated

The --database.force-sync-properties option was useful with the MMFiles storage engine, which has been removed in v3.7. The option does not have any useful effect if you use the RocksDB storage engine. From v3.11.0 onwards, it has no effect at all, is deprecated, and will be removed in a future version.

--agency.pool-size deprecated

The --agency.pool-size option was effectively not properly supported in any version of ArangoDB. Setting the option to anything but the value of --agency.size should be avoided.

From v3.11.0 onwards, this option is deprecated, and setting it to a value different than the value of --agency.size leads to a startup error.

Client tools

arangoexport

The default output file type produced by arangoexport, controlled by the --type startup option, has been changed from json to jsonl. This allows for more efficient processing of the files produced by arangoexport with other tools, such as arangoimport, by default.
