Splitting raises the shard count (finer partition ranges, e.g. <code>1 → 2</code>); merging lowers it (e.g. <code>2 → 1</code>).</p> <p>The reshard builds a hidden target rolling while the source keeps serving every read and write. Existing documents are streamed into the target with their <code>_id</code> preserved, the write tail is replayed until the target converges, and a single metadata commit then swaps the target in atomically. Documents stay addressable under the same <code>_id</code> and <code>_key</code> throughout, including for writes issued while the reshard is building.</p>
