This is a tracking bug for tasks concerning the improvement of Wikidata's dumps.
Hello guys - I am using Wikidata enriched with other data source, I must ingest the entire Wikidata JSON dump in a dev graph database of mine. That's easy (yet time-consuming) but once that's done, I want to keep my copy updated by querying the RecentChanges and LogEvents API endpoints to retrieve de changes/deletes/creates that occurred between two timestamps (I'd do so every few minutes) - that's relatively easy too!
How to get the cutoff timestamp for a given JSON dump? Where is this available or how to figure it out since the modified timestamp and lastrevid fields aren't present in JSON dumps.
@Lazhar: Please do not ask the same question in several tasks. Please see https://www.wikidata.org/wiki/Wikidata:Contact_the_development_team where to ask support questions that are not directly related to the task topic. Thanks for your understanding!
