URL: https://github.com/apache/seatunnel/pull/12187
### Purpose of this pull request
This pull request improves connector documentation for **Paimon** (Source &
Sink), **RocketMQ** (Source & Sink), and **Pulsar** (Source & Sink) in
accordance with connector documentation specifications (#4544).
Specifically, it addresses:
1. Adding missing `## Support Those Engines` (in `docs/en/...`) and `##
引擎支持` (in `docs/zh/...`) covering Spark, Flink, and SeaTunnel Zeta across
Paimon and Pulsar source docs, and standardizing engine headers across RocketMQ
docs.
2. Adding practical FAQs to clarify common production configurations:
- **Paimon Source:** Clarifies batch snapshot vs streaming changelog
modes, catalog/warehouse configuration, and column projection efficiency.
- **Paimon Sink:** Explains automated table creation from upstream
schema, 2PC checkpoint commit mechanism, and primary key (upsert) vs
append-only table modes.
- **RocketMQ Source:** Details multi-table reads with `tables_configs`,
starting offset modes (`EARLIEST`/`LATEST`/`TIMESTAMP`), and consumer
checkpoint recovery.
- **RocketMQ Sink:** Explains partition key hashing
(`partition.key.fields`), 2PC transactional messages for exactly-once
guarantees, and payload formatting.
- **Pulsar Source:** Covers partitioned topic subscription, partition
discovery intervals, consumer cursor recovery, and authentication token setup.
- **Pulsar Sink:** Explains `EXACTLY_ONCE` vs `AT_LEAST_ONCE` semantics,
dynamic multi-table topic routing, and supported serialization formats (`json`,
`text`, `avro`).
Fixes #12186
### Does this PR introduce _any_ user-facing change?
Yes. It improves official SeaTunnel documentation across English and Chinese
connector documentation pages.
### How was this patch tested?
Rendered and validated markdown syntax, tables, and headers across all 12
modified files in `docs/en/connectors/` and `docs/zh/connectors/`.
