JNSimba opened a new pull request, #3933:
URL: https://github.com/apache/doris-website/pull/3933
## Summary
Fix incorrect Streaming Job (CDC continuous load) syntax in the docs and add
a dedicated data type mapping reference page. Applied to both **dev (current)**
and **version-4.x**, EN + ZH.
## Syntax fixes (verified against the SQL parser grammar and regression
cases)
- **`PROPERTIES` placement**: must come **before** `ON STREAMING` (right
after the job name), not after. The previous order would fail to parse.
- **`max_interval`**: an integer number of **seconds** (e.g. `10`); a unit
suffix like `10s` is not accepted.
- **`s3.max_batch_bytes`**: a plain **byte count** (e.g. `10737418240`,
valid range 100MB–10GB); `10G` is not accepted.
- **`offset`**:
- Multi-table CDC (`FROM ... TO DATABASE`) defaults to `latest` (was
documented as `initial`).
- `cdc_stream` TVF requires `offset` (it has no default); fixed the param
tables and the examples that omitted it (and a trailing-comma issue in the zh
examples).
## Docs improvements
- **Continuous Load Overview**: add a **Limitations** section (primary-key
tables only; schema-change/DDL sync scope) placed just above the FAQ, and link
to the new mapping page.
- **New page – Data Type Mapping**: how upstream MySQL/PostgreSQL column
types map to Doris column types, with value-representation notes (unsigned
widening, JSON, Base64-encoded binary, timezone normalization, GeoJSON,
one-dimensional arrays, etc.). Registered in the sidebars.
No behavior change — documentation only.
