overture_core
Shared, framework-agnostic business logic — portable job classes built on overture-serverless.
overture-stac (and its pyarrow>=16 floor via stac-geoparquet) is an optional extra. Install overture-core[stac] (quote it in shells like zsh that glob brackets: pip install 'overture-core[stac]') if you need stac.job.PublishStac or stac.catalog.build_release_catalog. stac.latest_release_job.LatestRelease only reads the STAC root catalog over HTTPS via pystac, so it works without the extra. Plain overture-core covers the cloud/iceberg/versioning/uuids/uuids_sql modules too.
Modules
Framework-agnostic helpers, each importable on its own without pulling in the job classes below.
| Module | What it's for |
|---|---|
uuids |
Pure Python UUID v3/v4/v5 generators, no Spark dependency; wrap them in a UDF yourself. Also includes the newer RFC 9562 v6/v7/v8 generators, unavailable before Python 3.14. |
uuids_sql |
SQL-string equivalents of the uuids generators for Spark or Trino, so a UUID column can be computed server-side instead of round-tripping through a Python UDF. |
versioning |
Parse a source's version from an ISO 8601 date or an HTTP header into a consistent dated string, for sources with no explicit version metadata. |
iceberg |
Shared enums, dataclasses, and Spark SQL extensions for Iceberg + Sedona catalog configuration across platforms. |
cloud.cloud |
Provider-agnostic helpers for building partition path segments. |
cloud.aws.core |
AWS account, region, and role/assume-role helpers built on boto3. |
cloud.aws.object |
S3 object/prefix helpers built on boto3: URI parsing, existence checks, read/write/copy/delete, prefix listing. |
cloud.aws.codeartifact |
Mint a short-lived CodeArtifact authorization token. |
stac.catalog |
STAC catalog reads/writes backing the jobs below. |
Jobs
stac.job.PublishStac: publishes the Overture STAC catalog. Two modes selected by the presence of thereleaseparam:- single-release (
release+source_path+scratch_bucket): publish just that release, mirror scoped tostac/{release}/. Schema comes from the RC bundle'smetadata.json. - walk (no
release, requiresscratch_bucket): rebuild the catalog for every release currently in the public bucket, mirror the wholestac/prefix with delete-orphans. Schema per release comes from the existing STAC (schema:versionin eachcatalog.json); on cache miss the job self-heals by reading schema from the released RC bundle inscratch_bucketand raises if it can't recover.
- single-release (
stac.latest_release_job.LatestRelease: reads the STAC root catalog (root_href, defaults to the prod root) and resolves the newest release ID. Read-only, HTTPS-only, no AWS credentials or S3 access needed. Stashes the result onself.latest_releasefor a caller that instantiates the job directly instead of going throughrun().
Future work
- Bundle-owned schema accessor — when
ReleaseCandidateBundlebecomes publishable, moveread_schema_version_from_rc_bundleonto it asresolved_schema_version(); single-release mode's schema read shrinks to one line. - Upstream
build_release_catalog— file a PR against OvertureMaps/stac exposing this as a public API (their CLI already does the exact call sequence). When it lands, our wrapper collapses.
