Subject: | CA and data acquisition array with variable length in waveform record) |

Hi,
I would like to use EPICS for one system but there is one problem where I can't come to correct solution.
Data acquisition system gets data array. Array length always changes. For example, first measurement has 2000 length array. Next measurement has 50000 length array. Then 2002, 1500, 51000, and so on.
I can create waveform record with 100000 length that will satisfy max points in array. When client subscribes it must set counts of data array. And I, definitely, don't want to transfer 100000 data array each time.
Have anyone solved this?
Thanks, Andrei.
