1357-1367: Query building logic is correct.The pagination query building follows the established pattern. One minor observation: when filtering by root resource ID, the method adds
Query::limit(1)after already addingQuery::limit($batchSize), which could result in duplicate limit queries. Consider restructuring to avoid this duplication.- $queries = [Query::limit($batchSize)]; - if ($this->rootResourceId !== '' && $this->rootResourceType === Resource::TYPE_FUNCTION) { $queries[] = Query::equal('$id', $this->rootResourceId); $queries[] = Query::limit(1); + } else { + $queries = [Query::limit($batchSize)]; }

Learning: In the Appwrite API, the default page limit for listing collections is 25 records, so when using cursor-based pagination with Query::cursorAfter(), there's no need to explicitly specify Query::limit(25) as the API will default to this limit.

File: src/Migration/Sources/Appwrite/Reader/API.php:8-8
Timestamp: 2025-06-28T09:47:11.436Z
Learning: In the Appwrite migration codebase, commented-out Tables service references (import statements and constructor parameters) are intentionally kept for future implementation when the Tables service becomes available in the Appwrite SDK, rather than being dead code that should be removed.

1352-1356: LGTM! Proper pagination initialization.The initialization follows the established pagination pattern used throughout this codebase, with correct type annotation and infinite loop structure.
1368-1373: LGTM! Proper early termination handling.The API call and early return logic correctly handles the case when no functions are available, using appropriate strict comparison and void return.
1375-1411: LGTM! Efficient resource conversion and proper loop termination.The implementation correctly:
- Converts both functions and environment variables in a single pass
- Accumulates related resources for efficient callback processing
- Uses proper loop termination condition based on batch size
- Updates pagination cursor appropriately
This approach is more efficient than the previous single-fetch implementation and maintains consistency with other paginated export methods in the codebase.
