When will a 64Bit version of Data Services be available for Windows?

I have a job which is transforming data from multiple legacy systems into SAP. The job is using multiple Workflows and Dataflows to control the process flow.

WF_1 prepare data from system 1

dataflow_1a

dataflow_1b

dataflow_1c

WF_2 prepare data from system 2

dataflow 2a

dataflow 2b

dataflow 2c

Unfortunately the job consumes more than 2Gb of pageable memory. Each dataflow is configured as pageable, but routinely breaches the 2Gb limit and gets Access Violations.

The issue is caused by a delay in clearing the cache between dataflow executions. By placing a sleep command in a script this is providing the Windows OS and AL_engine with enough time to clear sufficient cache between the workflows.

Just wondering when a 64bit version of Data Services will be available on the Windows Platform?
