how to release formula transformations memory

[yiminghe]

when operating table for a long time, all formula transformations will be saved inside lazilyTransformingAstService, how to eager apply and release unused transformation ?

You would just have to create the methods yourself to clear transformations and combinedTransformer.

What's the use case for this though? As far as I can tell it looks to be needed for the calculations and for Undo/Redo functionality.

If operating table for a long time, memory keeps growing. undo redo will splice according to undoLimit, but transformations will not.
