How an application reaches a cluster had no home in the manual. Client routes were an H3 inside the
Address resolution page, so the site had no URL, no sitemap entry and no search result of its own
for them — sitemap.xml carries one <loc> per page, and someone searching "client routes" or
"Private Service Connect" got a result titled "Address resolution". VPC peering, Transit Gateway and
direct connections were not covered at all.

  • Add manual/core/connectivity/, an index that routes each kind of network to what the driver
    needs, and wire it into the core toctree.
  • connectivity/vpc_peering/ — the deployments where nodes are reachable at their broadcast
    addresses, so the driver needs no translation; links to the ScyllaDB Cloud guides for the setup
    itself rather than restating it.
  • connectivity/client_routes/ — the content moved out of Address resolution, carrying the alias
    prose that gives psc, pl and "private service connection" something to match. Titled after the
    Rust driver's connecting/client-routes.
  • Leave ### Client routes (cloud private endpoint deployments) behind as a pointer, so
    #client-routes-cloud-private-endpoint-deployments still resolves for docs: note that client routes are 4.x-only (DRIVER-1043) #1081's 3.x cross-link.

Verified with make -C docs test (-W --keep-going), green, 0 warnings: three new sitemap.xml
entries and three new searchindex.js titles — Connectivity, VPC peering, Transit Gateway and direct connections, Client routes (private networking); the preserved anchor still renders; and
the section sits between Compression and Configuration in the prev/next chain.

Not covered: none of this reaches a reader until a docs branch carries it — /stable/ is
scylla-4.19.0.x, frozen at 4.19.0.1, and its Address resolution page stops at "EC2 multi-region".
That is DRIVER-1036 / #1056, and it is why this wants to merge before 4.19.2.2 is tagged.
Verifying the above also turned up #1132: under MyST every in-body relative link on this branch
renders dead, these pages' included.

📝 Walkthrough

Walkthrough

The manual adds a Connectivity section covering node discovery and network setup, with guidance for VPC peering, AWS Transit Gateway, and direct internet connections. A new page documents client routes configuration, route refresh, DNS resolution, and platform limitations. The prior client routes guide now links to that page, and the upgrade guide points to its new location.

Merge Risk: 🟡 Moderate · up to e3a0a

Readers following the cloud configuration example can connect to localhost instead of their cluster. Correct that example and the remaining connection and DNS guidance before merging.

Do not promise a 30-second JDK DNS cache TTL.

The positive-cache default is implementation-dependent; it can also be indefinite with a security manager. Readers who rely on the stated 30-second default may keep using an old endpoint address. Describe the default as JVM-dependent and advise setting networkaddress.cache.ttl when a specific refresh interval is required. (docs.oracle.com)

copied as shown fails to connect. Configure the engine factory in the
builder and keep the HOCON block as the application.conf alternative.

exist before 4.19.0.7, so their page says so, carries the search
aliases, and explains why an address translator is no substitute.
Hostname-expansion and subnet-proxy text is dropped; neither exists
in this version.

* docs: enable TLS in the ScyllaDB Cloud connection example

The example connected to 9142, the TLS port, without enabling TLS, and
the truststore setup came only afterwards as a HOCON block, so the code
copied as shown fails to connect. Configure the engine factory in the
builder and keep the HOCON block as the application.conf alternative.
Say the TLS port is why the example needs TLS, and quote the truststore
password, which HOCON cuts at #.

Note the NullPointerException warning 4.18.1 logs on close when there
is no keystore, and say that a createUnresolved contact point is looked
up again on every connect rather than only at startup.
