Currently, a query defined withCREATE DISTRIBUTED QUERY
cannot be run in Interpreted Mode. However, interpreted queries can still run on a distributed graph with a regular, non-distributed execution model.
The list below includes additional limitations. These limitations are expected to be temporary. We are continuing to expand the capabilities of Interpreted Mode.
Distributed Query Mode
Any operation involving files

Attributes and accumulators
ArrayAccum
Accessing the previous value of a vertex-attached accumulator with the ' operator, e.g., src.@acc'
STRING COMPRESS
as accumulator type
Accessing the attribute of a vertex variable that is not a vertex alias defined in a FROM

Having the same name for global accumulators, global variables, and query parameters
For example, there cannot be a query parameter named param
and a global accumulator named @@param
within the same query
