Class SqlflowShardedMetadataAnalyzer

Object

gudusoft.gsqlparser.dlineage.dataflow.metadata.sqlflow.sharded.SqlflowShardedMetadataAnalyzer

All Implemented Interfaces:

MetadataAnalyzer<String>

public class SqlflowShardedMetadataAnalyzer
extends Object
implements MetadataAnalyzer<String>

Extracts metadata information (tables, views, procedures, relationships) from a sqlflow-sharded manifest and its catalog shards.

This class does NOT analyze SQL source code in queries, nor does it produce lineage for query objects. The lineage analysis of SQL queries is performed in DataFlowAnalyzer, which reads the source JSONL files through the databaseMap / appendSqlInfo mechanism and invokes the SQL parser to generate dataflow relationships.
