v1.0.15

[1.0.15] - 2026-07-30

Added

• datacontract test treats a server typed mssql as SQL Server, so contracts carrying the ODBC/dbt spelling are testable (ODCS itself only defines sqlserver)
• datacontract test --quality-id runs a single quality rule by its ODCS quality.id, and --tag runs every quality rule declaring one of the given quality.tags (#1080)
• Test results report the quality_id and tags of the quality rule a check comes from
• New databricks-runtime extra for installing inside a Databricks Runtime, where the cluster already provides PySpark: pip install datacontract-cli[databricks-runtime] (#1211 @chifu1234)
• The docs Commands reference documents the global options --version and --system-truststore, and every import and export guide links to its command page and back
• datacontract test --dimension runs only the checks measuring one data quality dimension, e.g. --dimension uniqueness; it matches the ODCS quality.dimension of a rule and the schema and service level checks that measure the same aspect
• New dataframe extra installs just what testing Spark DataFrames needs: pip install datacontract-cli[dataframe]
• datacontract import trino creates a data contract from a Trino catalog, including a ready-to-test servers block
• datacontract import oracle creates a data contract from a live Oracle database, including a ready-to-test servers block
• datacontract import gcs and datacontract import adls create a data contract from files in Google Cloud Storage or Azure Blob Storage, including a ready-to-test servers block
• datacontract import sqlserver creates a data contract from a live SQL Server database, including a ready-to-test servers block
• datacontract import mysql creates a data contract from a live MySQL database, including a ready-to-test servers block
• The documentation has a Release Notes page, generated from this changelog
• The documentation has a guide to migrate contracts from DCS to ODCS
• datacontract import s3 creates a data contract from files in an S3 bucket, including a ready-to-test servers block
• datacontract import athena creates a data contract from an Amazon Athena database, including a ready-to-test servers block
• datacontract import unity is now datacontract import databricks; the unity format name keeps working
• Redshift infers the authentication method: a password means a database login, otherwise your AWS session is used for IAM. DATACONTRACT_REDSHIFT_AUTHENTICATION is no longer required and remains as an override
• datacontract import postgres creates a data contract from a live Postgres schema, including a ready-to-test servers block
• datacontract import redshift creates a data contract from an Amazon Redshift schema, including a ready-to-test servers block
• Redshift supports IAM authentication, using temporary credentials from your AWS session instead of a database password
• datacontract import bigquery now generates a servers block, so datacontract test works right after the import
• datacontract test verifies declared primary keys: each key column must have no missing values, and the key must have no duplicates (a composite key is checked as a tuple) (#1220 @DMZ22)

Fixed

• datacontract test checked physicalType against a same-named table in another schema when one existed, because the native column types were read from the catalog without the contract's schema
• datacontract test against SQL Server no longer fails every check with "Could not read model" when server.schema differs from the login's default schema
• datacontract-cli[s3] could not run datacontract test, and datacontract-cli[gcs] was missing the AWS duckdb extension the GCS connection loads; each data source extra now installs everything its guide needs
• The API testing guide stated that no extra is required, but the response is tested with duckdb; it installs datacontract-cli[duckdb] now
• datacontract test told users to install datacontract-cli[local], an extra that does not exist, and datacontract-cli[api], which installs the web server rather than a test backend; both now point at duckdb
• datacontract import gcs wrote type: gcs, which is not an ODCS server type, so the imported contract failed datacontract lint and datacontract test; GCS is now written as an s3 server on the Google interoperability endpoint
• A data contract could inject SQL into the duckdb session through endpointUrl, which is interpolated into the statement that stores the S3, GCS and Azure credentials; every value is escaped now
• The datacontract api server accepted a local file path as the schema query parameter, so a caller could have it read files from the server's filesystem; only http(s) URLs are accepted now
• Trino physical type checks were silently skipped: its information_schema has no length or precision columns, so the catalog query failed and a wrong physicalType still passed
• datacontract import athena and datacontract import glue now honour DATACONTRACT_S3_ACCESS_KEY_ID and DATACONTRACT_S3_SECRET_ACCESS_KEY; the Glue catalog was read with ambient AWS credentials only
• S3 now uses an existing AWS session (aws sso login, AWS_PROFILE, instance roles) when no access key is configured; previously such a setup failed with 403 Forbidden
• Documented that Athena authenticates with an existing AWS session (aws sso login, AWS_PROFILE, instance roles); static access keys were presented as the only option
• regionName in an Athena servers block was ignored, so the region could only be set via DATACONTRACT_S3_REGION
• datacontract import glue mapped timestamp columns to logicalType: date instead of timestamp
• Testing and importing Redshift failed with codec not available in Python: 'UNICODE'
• Error messages no longer drop bracketed text such as pip install "botocore[crt]"
• BigQuery export failed on fields with logicalType: time
• Testing Parquet files failed for number fields without a declared precision and scale
• CSV and JSON imports now write detected formats (email, uuid, date-time) to logicalTypeOptions.format instead of a custom property, so they are validated by datacontract test
• SQL imports now map TIME types with precision or time zone (e.g. TIME(9)) to logicalType: time; previously the logical type was left unset
• datacontract test --checks quality now runs rowCount quality rules, which were wrongly categorized as schema checks
• datacontract import dbt derives the contract id from the dbt manifest's project_name instead of always emitting the placeholder my-data-contract (#1221 @DMZ22)
• A physicalType declaring a zero scale (NUMBER(38,0), decimal(18,0)) failed against its own column on Snowflake, Oracle, SQL Server and Databricks (#1377 @DMZ22)
• Snowflake physicalType checks failed for structured OBJECT, ARRAY and MAP columns, whose fields are now compared field by field instead of as rendered strings (#1377 @DMZ22)
• datacontract test on Athena failed a physicalType written in the Hive spelling datacontract import athena produces (array<string> against the reported array(varchar)) (#1377 @DMZ22)
• A physicalType declaring fractional seconds (TIMESTAMP_NTZ(9), datetime2(7), timestamp(3)) failed against its own column, so every timestamp column imported from Snowflake failed the first datacontract test
• datacontract test and datacontract import oracle read Oracle character lengths in bytes, so an NVARCHAR2(50) column was reported and checked as NVARCHAR2(100)
• datacontract test on Databricks could not check the element types of ARRAY, MAP and STRUCT columns, which the catalog reports as a bare type name
