Describe the new Parquet output session controls in the English and
Chinese current documentation: `enable_parquet_write_page_index`
(default `true`) and `parquet_write_data_page_size` (default 1 MiB).
Include an OUTFILE example, disabling/restoring the settings,
Hive/Iceberg/EXPORT scope, the Hadoop-framed LZ4 page target cap, and
tuning tradeoffs.

Implementation: apache/doris#69971

Version scope: current/Dev only. These controls are newly introduced on
master and are not available in released 4.x or 3.x, so their versioned
pages are intentionally unchanged.

Validation: both changed pages compile as Docusaurus-compatible MDX;
`git diff --check` passes. Changed-link lint reports two existing
`parquet_metadata_size_limit` anchor findings already present before
this change; the new OUTFILE links resolve. I18n lint flags the
intentionally current-only scope described above. A full website build
was not run.

…berg WriteInfo (#70209)

### What problem does this PR solve?

Issue Number: None

Related PR: #69392, #69971

Problem Summary:

**In short.** `doris_be_test` does not compile on master since #69971
was merged, so the BE UT of every PR fails with `BE BUILD FAIL`. This
fixes the one test case that breaks it.

**The problem.** #69392 replaced the `write_path`, `original_write_path`
and `target_path` fields of `IPartitionWriterBase::WriteInfo` with one
`IcebergOutputLocation location`, and updated the callers it knew about.
#69971, merged after it, added
`VParquetWriterTest.HiveAndIcebergParquetPageIndexOptions`, which still
sets the old fields:

```
be/test/format/transformer/vparquet_writer_test.cpp:380:41: error: no matching constructor for initialization of 'VIcebergPartitionWriter'
```

Each PR built alone, so both were green. TeamCity's BE UT has failed
this way for PRs merged with master `0eb5131db62` (for example build
1092024 of #69605).

**How this PR fixes it.** The case builds its `WriteInfo` as the other
Iceberg case in the same file does, `.location =
IcebergOutputLocation(".", ".")`. Nothing else changes.

…/JSON/WAL fixes (#70185)

### What problem does this PR solve?

Backport the following master PRs to `branch-4.2`, in master merge
order:

1. #69672 — Preserve source values and alias semantics in ES scans.
2. #69971 — Add session controls for Parquet page indexes and data-page
size.
3. #70155 — Repair ES source predicate regression cases.
4. #70079 — Fix ORC condition-cache seeks past filtered stripe suffixes.
5. #70154 — Preserve JSON and WAL rows with empty file projections.

The ES changes are adapted to the existing 4.2 FE planner and BE source
locations. Mapping safety, scan-wide read mode, local residuals, native
`esquery` handling and alias routing retain the upstream behavior
without introducing the master connector framework. Added adapter tests
cover both scan protocols, aliases, missing-value negations and native
residual rejection.

Preserve existing branch-specific ES regression coverage. Bring in the
previously absent predicate suite, adapting its plan assertions to 4.2's
`LOCAL_PREDICATES` output and retaining LIMIT result checks. Parquet
variables use the 4.2 annotation interface and the original optional
Thrift field IDs. The ORC dependency is pinned to the same fixed commit
as #70079.

The ES implementation also preserves source numeric and JSONB predicate
semantics after scan-wide fallback. Numeric-token rounding must not make
a remote predicate discard a row matching the value Doris materializes;
empty JSONB objects remain nonnull even when ES indexes no leaf.
Docvalue eligibility and pushdown are retained.

Mapped date formats and their order are carried per concrete backing
index through the existing property map to both scan protocols.
Calendar/epoch alternatives now distinguish basic_date from
epoch_millis, for strings and source numeric tokens. Numeric docvalues
and older FE numeric requests retain their epoch decoder. Typed alias
selection consistently uses the requested mapping type in schema
inference and planning. The pinned ORC decoder's libdeflate dependency
is included on ARM, matching master.

### Release note

Fix ES source-value filtering, mapped dates and typed alias query
correctness, ORC condition-cache seek crashes/missing rows and its ARM
link dependency, and JSON/WAL row counts for empty file projections. Add
Parquet output page-index and data-page-size session controls.

### Validation

- FE compilation and Checkstyle passed. ES validation: 81 tests (48
datasource/planner tests and 33 legacy ES tests), 0 failures/errors, 1
external-environment skip. The 9 Parquet session-variable tests passed.
- Rebuilt the pinned ORC dependency under AddressSanitizer: 56 focused
tests passed, including 32 filtered-stripe-suffix seek cases.
- Compiled all 10 affected Doris C++ implementation/test translation
units and the ORC fixture generator. The regenerated fixture is
byte-for-byte identical to the committed fixture.
- clang-format 16 checks passed for all affected Doris C++ sources and
headers. Modified Groovy suites compiled successfully.
- The ES reader/parser implementations and test translation units
compiled. The shared DATETIMEV2 date-format algorithm passed 21
standalone ASAN checks. CMake dependency checks passed for aarch64,
arm64 and x86_64; an actual ARM link was not run locally.
- Added `test_es_source_review_cases.groovy` with SQL-to-SQL checks
against an internal reference table for numeric/JSONB source predicates,
LIMIT, epoch-only formats, and explicit legacy DATETIMEV2 basic_date
columns. It covers both scanners and parallel-scroll settings, waits for
legacy metadata readiness, and restores session settings. The suite
compiled; no golden files were handwritten.
- The applicable ES fixes are synchronized to master in #70205. Master
already links libdeflate on every architecture.
- Full Doris BE unit-test execution and live external SQL regression
were not performed locally; CI validation is requested.
