[doc] remove single replica compaction documentation (#3870)
Remove all documentation and example references to the single replica
compaction feature (enable_single_replica_compaction /
max_single_replica_compaction_threads) across dev and 4.x, EN and ZH:
- compaction.md: drop the "Single replica compaction" section and the
max_single_replica_compaction_threads bullet
- be-config.md: drop the max_single_replica_compaction_threads entry
- CREATE-TABLE.md: drop the enable_single_replica_compaction property
row
- key-features/data-compaction.mdx: drop the related paragraph and
bullet
- connector tutorials, array-contains, basic-concepts, ccr/feature: drop
the example/reference occurrences of the property
Unrelated single-replica storage / data-import mentions are left intact.
## Versions
- [x] dev
- [x] 4.x
- [ ] 3.x
- [ ] 2.1 or older (not covered by version/language sync gate)
## Languages
- [x] Chinese
- [x] English
- [ ] Japanese candidate translation needed
## Docs Checklist
- [ ] Checked by AI
- [ ] Test Cases Built
- [ ] Updated required version and language counterparts, or explained
why not
- [ ] If only one language changed, confirmed whether source/translation
counterparts need sync

-## Single replica compaction
-
-By default, compaction for multiple replicas is performed independently, with
each replica consuming CPU and IO resources. When single replica compaction is
enabled, only one replica performs the compaction. Afterward, the other
replicas pull the compacted files from this replica, resulting in CPU resources
being consumed only once, saving N - 1 times CPU usage (where N is the number
of replicas).

-Single replica compaction is specified in the table's PROPERTIES via the
parameter `enable_single_replica_compaction`, which is false by default
(disabled). To enable it, set the parameter to true.

-This parameter can be specified when creating the table or modified later
using:
-```sql
-ALTER TABLE table_name SET("enable_single_replica_compaction" = "true");

-
-By default, compaction for multiple replicas is performed independently, with
each replica consuming CPU and IO resources. When single replica compaction is
enabled, only one replica performs the compaction. Afterward, the other
replicas pull the compacted files from this replica, resulting in CPU resources
being consumed only once, saving N - 1 times CPU usage (where N is the number
of replicas).

-Single replica compaction is specified in the table's PROPERTIES via the
parameter `enable_single_replica_compaction`, which is false by default

using:

4. **Promote to base.** When a cumulative output grows past
`compaction_promotion_size_mbytes` (1 GB by default), it's eligible for base
compaction the next round.
5. **Replace and clean up.** The output rowset replaces its inputs in tablet
metadata. Old files stick around for a grace window in case a query is still
reading them, then get deleted.

- Any table that takes frequent loads. The defaults already work; the question
is just whether to switch policies.
- Append-only logs and metrics. `time_series` reduces write amplification
because each rowset participates in compaction once, not repeatedly across size
tiers.
- Wide tables (dozens of columns or more). Keep `enable_vertical_compaction =
true` so big merges don't blow up memory.
-- Multi-replica clusters where compaction CPU is a bottleneck. Turn on
`enable_single_replica_compaction`.

| light_schema_change | Whether to use the Light Schema Change optimization.
If set to `true`, addition and subtraction operations on value columns can be
completed faster and synchronously. This feature is enabled by default in

process will skip all tablets of this table. |
-| enable_single_replica_compaction | Whether to enable single-replica
compaction for this table. If this property is set to `true`, only one replica
of all replicas of the table's tablets will perform the actual compaction
action, and other replicas will pull the compacted rowset from that replica. |

Aggregate, or Duplicate is specified when creating a table, a Duplicate model
table without sort columns and prefix indexes will be created by default. |
| skip_write_index_on_load | Whether to enable not writing indexes during data
import for this table. If this property is set to `true`, indexes will not be
written during data import (currently only effective for inverted indexes), but
will be delayed until compaction. This can avoid the CPU and IO resource
consumption of writing indexes repeatedly during the first write and
