New rows went into free space scattered through the 9.6 GB heap on the HDD
(left behind by inspection's updates): one random HDD read per insert, and
seed batches took a median 13 s to store. The existing table becomes the
first partition as it is (a CHECK scan, no rewrite; indexes, its foreign
key and the triggers are taken over by the partitioned parent); new
partitions of 4M ids go in the same tablespace and stay in memory while
they fill.
- Every partition has a unique file_key index; FileStore.insert looks keys
up in all partitions first (a key can't be unique across partitions).
- FilePartitions.ensure() (gc:scheduler) keeps two partitions ahead.
- Stats count files from the partitions; seed:node waits ~20 minutes for
the API before giving a range up.

The seed API keeps a pool of NNTP connections (SEED_NNTP_CONNECTIONS) and
serves GET /api/v1/seed/ranges/:id/chunk?from=&to= for leased ranges:
the gzip stream the news server sent, passed on unopened. seed:node fetches
that way by default (SEED_FETCH=relay), so a node needs only a token and
SEED_CONNECTIONS; SEED_FETCH=direct keeps its own NNTP connections. All
fetching then comes from the indexer's IP (the account allows two).

A failed NNTP login gives the range back uncounted (no attempt used), and a
node with nothing to lease holds no connection. Replaces log-in-before-lease,
which kept idle connections and logged in again every minute while idle.

- seed:node logs in to NNTP before taking a range and keeps the connection
across ranges (replaced after 2 minutes idle or a failed range). A node
that can't reach its news server takes no range: two ranges were set
aside as failed while an office node's tunnel was being set up
(ECONNREFUSED 127.0.0.1:1563, five leases each). After an IP-address
limit refusal it waits 5 minutes.
- NNTP_TLS_SERVERNAME: the hostname the TLS certificate is checked
against when NNTP_HOST is a tunnel ("Hostname/IP does not match
certificate's altnames: Host: localhost").
- seed-node/README: the IP-address limit and tunnelling.

At most two posts waiting; a failed post stops the chain, so nothing is
stored past a missing batch. The first remote node did 7k headers/s while
waiting for every post.

- seed_nodes (hashed bearer tokens) and seed_ranges (planned ranges with
lease, resume point and counts); migration …140.
- SeedOrchestrator: lease (oldest plan first, FOR UPDATE SKIP LOCKED; a
lease without a batch for 15 min passes to the next node and resumes at
next_id), batch (stores files and fragments, moves next_id), finish,
release, plan (from below live indexing / the backfill / earlier plans
down to N days back; takes over the group's backfill), status.
- Seed API under /api/v1/seed (lease, ranges/:id/batches|done|release,
status) behind a node-token middleware; JSON bodies up to 64 MB after
gzip.
- seed:node runs a node: no database or Redis, outgoing HTTPS only, N
connections, gzip batches, retries for network errors and 5xx, drops a
range on 409, gives its ranges back on SIGTERM. seed-node/ has a compose
file that builds the image from this repository.
- seed:token, seed:plan, seed:status for the operator. Header parsing moved
to lib/ingest and the range loop to lib/seed/runner, shared by seed:range
and seed:node.
