verify_schema_capabilities

def verify_schema_capabilities(schema: Schema,
capabilities: DestinationCapabilitiesContext,
destination_type: str,
warnings: bool = True) -> List[Exception]

[view_source]

Verifies load_tables that have all hints filled by job client before loading against capabilities. Returns a list of exceptions representing critical problems with the schema. It will log warnings by default. It is up to the caller to eventually raise exception

  • Checks all table and column name lengths against destination capabilities and raises on too long identifiers
  • Checks if schema has collisions due to case sensitivity of the identifiers

column_type_to_str

def column_type_to_str(column: TColumnType) -> str

[view_source]

Converts column type to db-like type string

resolve_merge_strategy

@with_config
def resolve_merge_strategy(
tables: TSchemaTables,
table: TTableSchema,
destination_capabilities: Optional[
DestinationCapabilitiesContext] = ConfigValue
) -> Optional[TLoaderMergeStrategy]

[view_source]

Resolve merge strategy for a table, possibly resolving the 'x-merge-strategy from a table chain. strategies selector in destination_capabilities is used if present. If table does not contain strategy hint, a default value will be used which is the first.

destination_capabilities are injected from context if not explicitly passed.

Returns None if table write disposition is not merge
