mcp-data-platform-v0.8.0

Release Notes: v0.8.0

Highlights

Lineage-Aware Semantic Enrichment - Downstream datasets now automatically inherit column metadata from upstream sources via DataHub lineage. Query an undocumented Elasticsearch index and get descriptions, glossary terms, and tags from its Cassandra source table.

New Features

Lineage-Aware Column Inheritance

When describing a table with undocumented columns, the platform now:

1. Queries DataHub for upstream lineage
2. Fetches schemas from upstream datasets
3. Matches columns and inherits metadata
4. Returns enriched response with provenance tracking

Configuration:

semantic:
  provider: datahub
  instance: primary

  lineage:
    enabled: true
    max_hops: 2
    inherit:
      - glossary_terms
      - descriptions
      - tags
    prefer_column_lineage: true

    column_transforms:
      - strip_prefix: "rxtxmsg.payload."

    aliases:
      - source: "cassandra.prod_fuse.system_sale"
        targets:
          - "elasticsearch.default.jakes-sale-*"

Response format:

{
  "column_context": {
    "amount": {
      "description": "Net sale amount",
      "glossary_terms": [{"name": "Net Sale Amount"}],
      "inherited_from": {
        "source_dataset": "urn:li:dataset:cassandra.system_sale",
        "source_column": "initial_net",
        "hops": 1,
        "match_method": "name_transformed"
      }
    }
  },
  "inheritance_sources": ["urn:li:dataset:cassandra.system_sale"]
}

Match methods:

Method	Description
column_lineage	DataHub column-level lineage edges
name_exact	Exact column name match
name_transformed	Match after strip prefix/suffix
alias	Explicit alias configuration

Dependencies

• Requires mcp-datahub v0.4.0 (for GetColumnLineage and GetSchemas methods)

Breaking Changes

None. Lineage inheritance is opt-in (lineage.enabled: false by default).
