getMaxRetransmitSlot
Last updated:
`getMaxRetransmitSlot` returns the **highest slot seen from the retransmit stage** — the point in the validator's turbine pipeline where shreds received from peers are forwarded on. It is a single slot number reflecting how far the node has progressed in propagating blocks across the cluster.
This is a low-level **diagnostic** metric, primarily useful for observing a node's ingest/forwarding progress rather than for application data. To track the slot a node will actually serve confirmed reads from, prefer [`getSlot`](./getSlot.md); to see how far shred insertion has advanced, compare with [`getMaxShredInsertSlot`](./getMaxShredInsertSlot.md).
> **Gotchas** > - The value is node-local and reflects pipeline state, not network finality — > it is not a confirmed or finalized slot and should not be used as a read > floor for fetching block data. > - It advances continuously as the node receives shreds; do not cache it.
