handler = workflow.run(...)
result = await handler
handler = workflow.run(ctx=handler.ctx, ....)
result = await handler
You can also serialize the context (the pickling-serializer is opt in, in case you are storing non-json serializable objects in the context)
from llama_index.core.workflow.context_serializers import JsonSerializer, JsonPickleSerializer
# serialize
serialized_context = handler.ctx.to_dict(serializer=JsonSerializer())
# resume at a later point
ctx = Context.from_dict(serialized_context, serializer=JsonSerializer())
