… JDBC lock backends - Use --warehouse/--database/--table in the action jar compact example; --path has been rejected by ActionFactory since apache#4728. - Use --database/--table in the expire_snapshots action example and drop the unused --version argument. - Add spark.paimon.scan.preserve-data-grouping to the Spark bucketed join examples, which is required since apache#10076. - List PostgreSQL among the databases supporting the JDBC catalog lock. - Fix broken external links in the Variant, filesystem and PyPaimon SQL docs.

The Flink action arguments, Spark grouping option, and JDBC dialect list match the current implementation. The local Docusaurus production build and OpenAPI validation pass, and all three replacement URLs respond with HTTP 200. One link still needs to lead readers to the correct engine.

[P2] Link to the Trino setup guide
The new URL opens a Presto guide that installs the jars under $PRESTO_HOME/plugin/hive-hadoop2/. Readers following this Trino section still have to translate Presto-specific paths and setup steps. Please link to the Trino guide and identify its OSS-HDFS scope. Alibaba Cloud Trino guide
