Breaking Changes

• Breaking changes to arango.ArangoClient:

  • Replaced parameters protocol, host and port with hosts and host_resolver. Example:

    from arango import ArangoClient
    
    # OLD
    client = ArangoClient(protocol='http', host='localhost', port=8529)
    
    # NEW (single host)
    client = ArangoClient(hosts='http://localhost:8529')
    
    # NEW (multiple hosts with "roundrobin" or "random" host resolver)
    client = ArangoClient(hosts=['http://host1:8529', 'http://host2:8529'], host_resolver='roundrobin')

  • Replaced properties protocol, host, port and base_url with hosts. Example:

    from arango import ArangoClient
    
    # OLD
    client = ArangoClient(protocol='http', host='localhost', port=8529)
    client.protocol
    client.host
    client.port
    client.base_url
    
    # NEW
    client = ArangoClient(hosts='http://localhost:8529')
    client.hosts

• Breaking changes to transactions:

  • Changed the parameters in Database.begin_transaction.
  • Context managers are no longer offered (you must commit the transaction yourself).
  • On API execution, results are now returned immediately instead of TransactionJob objects.
  • To abort transactions, you must call TransactionDatabase.abort_transaction method.
  • Removed exception arango.exceptions.TransactionStateError.
  • Removed exception arango.exceptions.TransactionJobResultError.
  • See examples here.

• Breaking changes to AQLQueryCache (Database.aql.cache):

  • Renamed parameter limit to max_results in method AQLQueryCache.configure.
  • Renamed field limit to max_results in the result of method AQLQueryCache.properties.
  • See examples here.

• Breaking changes to arango.request.Request:

  • Removed properties read, write and command.
  • The content of property data is no longer serialized.

• Removed method Database.ping (all it did was send a get API call which you can always do yourself).

• Changed the abstract class for custom HTTP clients (arango.http.HTTPClient). See new examples of defining your HTTP clients here.
