Purpose

Linked issue: Not required; this is a documentation correctness fix.

The configuration reference documents three keys that do not exist in ConfigOptions, so following the docs does not configure what the description says.

table.auto-inc.batch-size (engine-flink/options.md) is the previous name of the option now declared as table.auto-increment.cache-size. The description text is otherwise identical, and table-design/table-types/pk-table.md already refers to the option by its current name. Because the key starts with table., creating a table with the documented name is rejected by TableDescriptorValidation as an unrecognized table property, with a message that points at the cluster version rather than at the key.

The two server keys in maintenance/configuration.md use a hyphen where the code uses a dot:

• kv.snapshot.lease-expiration-check-interval → kv.snapshot.lease.expiration-check-interval
• kv.rocksdb.shared-rate-limiter-bytes-per-sec → kv.rocksdb.shared-rate-limiter.bytes-per-sec

Neither resolves to an option, so a value written to server.yaml under these names is ignored. For the rate limiter this is easy to miss, since the same entry is described as dynamically updatable and engine-flink/procedures.md spells the dotted name.

Brief change log

• website/docs/engine-flink/options.md: rename table.auto-inc.batch-size to table.auto-increment.cache-size, and write the default as 100000 instead of 100000L, like the other Long rows in the same table.
• website/docs/maintenance/configuration.md: use the dotted key names for the snapshot lease check interval and the shared rate limiter.

Tests

Documentation only. Each new key was checked against its declaration:

• table.auto-increment.cache-size — ConfigOptions.java:2292, defaultValue(100000L)
• kv.snapshot.lease.expiration-check-interval — ConfigOptions.java:2458, durationType(), Duration.ofMinutes(10)
• kv.rocksdb.shared-rate-limiter.bytes-per-sec — ConfigOptions.java:2556, memoryType(), Long.MAX_VALUE

API and Format

None.

Documentation

Corrects three configuration keys that do not resolve to any option in ConfigOptions.

Thanks for fixing these stale configuration keys
