Fastest way to update a value

[Gareth_Spencer]

hi Scott

Thanks for this.

Does this slide:
suggest that importing a list and "bulk import" via API in fact go through the same process exactly, once loaded?  And therefore does this take the same total time to process?

Also, what reporting is available after bulk import via API, in case of errors that require amendment (v the error reporting available in list import)?

i.e. What are the pros and cons of each method?

Thanks.

ok, after testing both way, here are the figures within a same instance:

- 170 000 persons one field updated = 420 minutes // Smart campaign

- 170 000 persons one field updated =   30 minutes // List import

I'm going to compare with bulk API too.

BR,

Charles
