1322630531 opened a new pull request, #11792:
URL: https://github.com/apache/seatunnel/pull/11792

   ### Purpose of this pull request
   
   Fixes #11620.
   
   Pulsar Source advertises `format = text`, but its runtime validation and 
deserialization path reject it. This patch:
   
   - allows `text` in single-table source configuration;
   - builds `TextDeserializationSchema` with the configured `field_delimiter`;
   - keeps the multi-table restriction explicit;
   - updates the English and Chinese Pulsar Source documentation and examples.
   
   ### Does this PR introduce _any_ user-facing change?
   
   Yes.
   
   Previously, a single-table Pulsar Source configured with `format = text` 
failed validation (and would also fail during deserializer creation). After 
this change, text messages are deserialized according to the configured schema 
and `field_delimiter`. Multi-table mode continues to support only JSON, 
CANAL_JSON, and AVRO.
   
   ### How was this patch tested?
   
   - Added a positive regression test for single-table text deserialization 
with a custom `|` delimiter.
   - Added configuration tests that allow text in single-table mode and 
explicitly reject it in `tables_configs`.
   - Ran all 9 Pulsar unit test classes: **46 tests, 0 failures, 0 errors, 0 
skipped**.
   - Ran the Reactor build with Spotless checks enabled:
   
   ```shell
   mvn -B -pl seatunnel-connectors-v2/connector-pulsar -am verify   
"-Dtest=PulsarConfigUtilTest,PulsarMultiTableConfigTest,PulsarSinkFactoryTest,PulsarSinkWriterTest,MultiTablePartitionDiscovererTest,PulsarCanalDecoratorTest,PulsarSourceFactoryTest,PulsarSourceTest,PulsarSourceReaderRestoreTest"
   "-Dsurefire.failIfNoSpecifiedTests=false"   "-DskipIT=true"   
"-Dlicense.skipAddThirdParty=true"   "-Dskip.ui=true"
   ```
   
   ### Check list
   
   * [x] No new JAR binary package is added.
   * [x] Updated the English and Chinese connector documentation.
   * [x] This change does not introduce an incompatibility.
   * [x] This is an existing connector bug fix; new connector registration 
steps are not applicable.
