User story:

To make the app as responsive as possible, the filtering will be performed either locally or by the back-end depending on the total number of clusters. If the user has over 5000 expected clusters, filtering will be performed by the back end, but if the user has less or equal to 5000 (or the limited determined in OCMUI-1784) expected clusters, filtering will done locally.

Acceptance criteria:

• If the user has an expected number of clusters over 5000 (or what is determined in OCMUI-1784), filtering will be done on the back-end. For every change in the filter, the data is prefetched.
• If the user has an expected number of clusters less than or equal to 5000 (or what is determined in OCMUI-1784), filtering will be performed locally. This means that the data will not be refetched when there is a change in the filter.
