Iterating Over Large Collections

Current API may return an arbitrary count of 100000000 for large collections (tables). This doesn’t mean that collection doesn’t contain more records. We have an open change request to augment this behavior and return null in such cases (as returned value cannot be trusted).

We recommend to implement “blind iteration” even before mentioned change is implemented as it will allow to fetch all records with the current as well as future API implementation.

Blind iteration pseudo-code

limit = 500
start = 0
returned_count = limit

while returned_count == limit do
  batch, returned_count = fetch_data(start, limit)
  start += returned_count

  # process returned batch

Blind iteration was already introduced into IP Fabric Python SDK v5.0.1.
