opteryx-upload

Python client SDK for the Opteryx Upload Service.

Install

pip install opteryx-upload

Usage

from opteryx_upload import UploadClient, Target, ConflictResolution

client = UploadClient(token="<jwt>")  # or token=lambda: fetch_fresh_token()

session = client.create_session()
session.upload_file("findings.parquet")
session.upload_file("more_findings.csv")  # auto-split into <30MB parts if needed

result = session.inspect()
if result.has_issues:
    raise SystemExit(result.issues)

commit = session.commit(
    Target(workspace="acme", collection="security", dataset="findings"),
    snapshot_message="Initial load",
    conflict_resolution=ConflictResolution.APPEND,
)
print(commit.table, commit.commit_id, commit.rows_written)

Or in one call:

client.upload_and_commit(
    ["findings.parquet"],
    Target("acme", "security", "findings"),
    snapshot_message="Initial load",
)

Authenticating with a Personal Access Token (PAT)

If you have a PAT (client_id + client_secret) instead of a ready-made JWT, use PATAuthenticator to exchange it for a short-lived access token. It caches the token and transparently re-authenticates before it expires, so you can pass it straight through as token=:

from opteryx_upload import UploadClient, PATAuthenticator

auth = PATAuthenticator(client_id="<client_id>", client_secret="<pat_secret>")
client = UploadClient(token=auth)

This exchanges the PAT via POST {auth_url}/token with grant_type=client_credentials (default auth_url is https://authenticate.opteryx.app), the same flow used by the opteryx-sqlalchemy driver. If the API ever rejects a token as expired/invalid, call auth.invalidate() and retry to force a fresh exchange.

Examples

Each UploadSession maps directly onto the service's REST flow: create a session, stage one or more parts, inspect them, then commit. See the service README for the underlying HTTP API these calls wrap.

End-to-end: upload and commit a dataset

from opteryx_upload import UploadClient, Target, ConflictResolution

client = UploadClient(token="<jwt>")

session = client.create_session()
print(session.info.session_id, session.info.expires_at)  # sessions expire after 6 hours

session.upload_file("findings.parquet")
session.upload_file("more_findings.parquet")

result = session.inspect()
print(result.rows_estimate, result.schema)
if result.has_issues:
    for issue in result.issues:
        print(f"part {issue.part}: {issue.issue}")
    raise SystemExit("fix the reported issues before committing")

commit = session.commit(
    Target(workspace="acme", collection="security", dataset="findings"),
    snapshot_message="Initial load of findings",
    conflict_resolution=ConflictResolution.FAIL,  # default: error if the dataset already exists
)
print(f"committed {commit.rows_written} rows across {commit.files_created} files as {commit.commit_id}")

Choosing a conflict resolution strategy

• ConflictResolution.FAIL (default) — reject the commit if the dataset already exists.
• ConflictResolution.APPEND — add the new rows to the existing dataset (schemas must match).
• ConflictResolution.OVERWRITE — replace the existing dataset's contents entirely.

session.commit(
    Target("acme", "security", "findings"),
    conflict_resolution=ConflictResolution.OVERWRITE,
)

Uploading many files, then deciding what to commit

Parts can be staged incrementally (e.g. from multiple upload jobs) before a single commit, and a bad part can be removed before it's committed:

session = client.create_session()
part_numbers = []
for path in ("2026-01.parquet", "2026-02.parquet", "2026-03.parquet"):
    part_numbers += session.upload_file(path)

result = session.inspect()
if result.has_issues:
    bad_part = result.issues[0].part
    session.delete_part(bad_part)
    result = session.inspect()

session.commit(Target("acme", "security", "findings"))

Handling errors

from opteryx_upload import (
    UploadClient,
    ConflictError,
    SessionExpiredError,
    UnprocessableEntityError,
)

client = UploadClient(token="<jwt>")
session = client.create_session()

try:
    session.upload_file("findings.csv")
    session.commit(Target("acme", "security", "findings"))
except UnprocessableEntityError as exc:
    print(f"file rejected: {exc}")
except ConflictError as exc:
    print(f"commit conflict, consider ConflictResolution.APPEND/OVERWRITE: {exc}")
except SessionExpiredError:
    session = client.create_session()  # start over with a fresh session

One-shot upload

For simple jobs where you just want to push files straight into a table:

client.upload_and_commit(
    ["findings.parquet"],
    Target("acme", "security", "findings"),
    snapshot_message="Initial load",
)

Authenticating with a PAT end-to-end

from opteryx_upload import UploadClient, PATAuthenticator, Target

client = UploadClient(
    token=PATAuthenticator(client_id="acme-etl", client_secret="opt_XXXXXXXX_01"),
)
client.upload_and_commit(["findings.parquet"], Target("acme", "security", "findings"))

Notes

• Files are auto-typed from their extension (.parquet, .csv, .ndjson/.jsonl).
• CSV and NDJSON files larger than the part size limit are automatically split into multiple parts (CSV chunks repeat the header row). Parquet is a binary format and cannot be split this way — write multiple smaller parquet files and upload each as a separate part if a single export is too large.
• Errors map to typed exceptions (AuthenticationError, SessionExpiredError, ConflictError, UnprocessableEntityError, etc.) so callers can catch specific failure modes instead of parsing HTTP status codes.
• token may be a plain string or a zero-arg callable, so short-lived JWTs can be refreshed transparently between requests.
