+
+> Retrieve GlideRecord results in batches (pagination) to avoid large query memory issues.
+
+**Use case:**  
+During a data-cleanup automation, I hit performance issues when querying 20k+ incidents. This helper lets you fetch results in pages (e.g., 100 at a time).
+
+```javascript
+/**
+ * paginatedQuery(table, query, limit, callback)
+ * Executes callback for each batch of records.
+ */
+function paginatedQuery(table, query, limit, callback) {
+  var offset = 0, hasMore = true;
+  while (hasMore) {
+    var gr = new GlideRecord(table);
+    gr.addEncodedQuery(query);
+    gr.orderBy('sys_created_on');
+    gr.setLimit(limit);
+    gr.setOffset(offset);
+    gr.query();
+
+    var count = 0;
+    while (gr.next()) {
+      callback(gr);
+      count++;
+    }
+
+    if (count < limit) {
+      hasMore = false;
+    } else {
+      offset += limit;
+    }
+  }
+}
+
+// Example:
+paginatedQuery('incident', 'active=true', 100, function(gr) {
+  gs.info('Processing ' + gr.number);
+});
