Note that these operators are counting the number column-like + arguments. A function that takes only a single column but several literal + values would still be a `UnaryOp`. + - Define the `name` of the operation and any parameters it requires. + - Implement the `output_type` method to specify the data type of the result. + +2. **Export the new operation:** + - In `bigframes/operations/__init__.py`, import your new operation dataclass and add it to the `__all__` list. + +3. **Implement the user-facing function (pandas-like):** + + - Identify the canonical function from pandas / geopandas / awkward array / + other popular Python package that this operator implements. + - Find the corresponding class in BigFrames. For example, the implementation + for most geopandas.GeoSeries methods is in + `bigframes/geopandas/geoseries.py`.

Specialized versions like + :func:`~bigframes.bigquery.ai.generate_bool`, + :func:`~bigframes.bigquery.ai.generate_int`, and + :func:`~bigframes.bigquery.ai.generate_double` are available for structured + outputs. +* **Embeddings:** Generate vector embeddings for text using + :func:`~bigframes.bigquery.ai.generate_embedding`, which are essential for + semantic search and retrieval-augmented generation (RAG) workflows. +* **Classification and Scoring:** Apply machine learning models to your data for + predictive tasks with :func:`~bigframes.bigquery.ai.classify` and + :func:`~bigframes.bigquery.ai.score`. +* **Forecasting:** Predict future values in time-series data using + :func:`~bigframes.bigquery.ai.forecast`. + +**Example usage:** + + >>> import bigframes.pandas as bpd + >>> import bigframes.bigquery as bbq + + >>> df = bpd.DataFrame({ + ...

Install dependencies: + ```bash + npm install + ``` + +2. Start the local development server: + ```bash + npm run start + ``` + Navigate to `http://localhost:4200/`.

generate component component-name +``` + +For a complete list of available schematics (such as `components`, `directives`, or `pipes`), run: +```bash +ng generate --help +``` + +## Running Tests + +To execute unit tests: +```bash +npm run test +``` + +## Packaging for Python + +Before testing the widget inside a Jupyter notebook or committing changes, compile the Angular app and bundle it so that the Python backend can load it: +```bash +npm run build:widget +``` + +This command compiles the project in production mode and then triggers `bundle.js` (via `esbuild`) to bundle the browser artifacts into a single unified ES module file at `../table_widget_angular.js`. diff --git a/bigframes/display/table_widget_angular/angular.json b/bigframes/display/table_widget_angular/angular.json

Instead of downloading large datasets to a local environment, BigFrames translates your Python code into optimized SQL, executing complex transformations across the BigQuery fleet. + +* **Petabyte-Scale Scalability:** Effortlessly process datasets that far exceed local memory limits. +* **Familiar Python Ecosystem:** Use the same ``read_gbq``, ``groupby``, ``merge``, and ``pivot_table`` functions you already know from pandas. +* **Integrated Machine Learning:** Access BigQuery ML's powerful algorithms via a scikit-learn-like interface (``bigframes.ml``), including seamless **Gemini AI** integration. +* **Enterprise-Grade Security:** Maintain data governance and security by keeping your data within the BigQuery perimeter. +* **Hybrid Flexibility:** Easily move between distributed BigQuery processing and local pandas analysis with ``to_pandas()``. + +Core Components of BigFrames +---------------------------- + +BigQuery DataFrames is organized into

SQL expression type(s) + Python type(s) + Notes + Examples +
Column expression (usable in a SELECT clause) + + + Both Python Series and column expression should be supported as inputs, + with the output reflecting the users input. Use a TypeVar + rather than directly using union types to make type checking easier. +

+Special considerations for Series inputs: +

+If an input and output are both a Series with the same number of rows, make sure +the output Series is implicitly (row identity) alignable with the original +input. In other words, don't generate a table expression. +

+If there are multiple Series inputs, they should be implicitly aligned if +possible so as not to generate unnecessary table expressions. +

Most scalar functions accept one or more column expressions as input. +
Scalar values + + + Theoretically, we could try to get the type system to help the user + disambiguate between this case and the "Column expression" case, but I think + that's more trouble than it it's worth with regards to the expectations of + Python users. + + +
Table expression + bpd.DataFrame +

+All columns are included as normal columns in the input table expression, +including named index columns. If column names aren't unique or contain +characters not compatible with BigQuery flexible column names, raise an error. +

+Outputs are unordered and unindexed to allow for cleaner mapping with SQL. +

Most APIs that take a table expression as input, also output a table + expression with the same number of rows and passing through all unused + columns. + +

This should be used to pass through any index or ordering columns (as well + as all other columns, if that's the SQL behavior), to allow for easy joining + with the original input DataFrame. +

Same number of rows as the input, so we should preserve index and ordering: + + + +

+ Different number of rows in output, so no need to preserve index or ordering. + Default index / ordering should be specified with the Session's + configuration: + +

+ +

+ Possible to have the same number of rows as the input, but joining with the original goes against the purpose of the feature: + +

+ +
Table name + string (referring to fully-qualified table ID, e.g. project.dataset.table / project.catalog.namespace.table) + Some SQL APIs do not support or have limitations with arbitrary table expressions, instead taking in a table ID, such as TABLESAMPLE expression. +

+Also, SEARCH and VECTOR_SEARCH, if you want the indexes attached to the table to actually apply. +

+For outputs, it might be preferable to output a table ID instead of a DataFrame, if the user is explicitly creating a table. For example, to_gbq() returns a string with the table name, which is useful for the case where BigFrame generates the table ID for the user. +

All of the items from the "Table expression" row above. APIs that require a table expression, but don't take a table ID can trivially take a table ID through a (SELECT * FROM table) subquery. +

+Some APIs only take a table ID and not an arbitrary table expression:

+ +
Aggregated table expression + DataFrameGroupBy + + + +
Analytic table expression +
    + +
  • DataFrameGroupBy - feasibility TBD +
  • Deferred column Expression with a Window applied.
+ + 		+ + +
Column name (unqualified*) \ + \ +*I've only encountered examples where the table name / table expression is passed in separately. + string, +

+For cases where the column name is used as an alias and we aren't using named Series: +

+dict[str, Expression] +

Often a table expression input is paired with a column name input, as is the case with the CREATE MODEL and VECTOR_SEARCH APIs +

+If SQL expects a column name rather than a column expression, do not attempt to change this in Python. For example, don't allow a Series as a substitute for DataFrames + Column name. \ + \ +If the associated table expression is input as a DataFrame, validate that these map cleanly to SQL and raise a ValueError if not. For example: \ +

    + +
  • Duplicate column names (excluding unnamed index columns). +
  • Column names that are some hashable value other than integer (which maps cleanly to a column name) or string. +
  • Any column name containing a punctuation mark that is not allowed by BigQuery flexible column names, such as ! or $.
+ + 		+ +
Literal values + corresponding literal Python value (e.g. int, float, string) + For cases where scalar values are also supported, it should be safe to start with this and then expand to support expressions without a breaking change, as is done in https://github.com/googleapis/google-cloud-python/pull/16606. + Most scalar functions accept one or more literal values as input. +
Scalar subqueries + Not supported yet, except implicitly in some aggregation use cases. +

+Would need some sort of bigframes deferred expression that can be tied to a table expression. +

+(Possibly DataFrame with 1 column?) +

+ +
+ +## Python policies + +### Naming + +Take the SQL function name, keyword name (used as a function name in Python), or argument name and transform them to lower_snake_case to reflect Python conventions. + +### Internal expressions + +Prefer creating deferred BigFrames expression objects where feasible. For +example, all scalar outputting functions should return a +`bigframes.pandas.Series` or `bigframes.core.col.Expression` that wraps a +`bigframes.core.expression.Expression`. + +Prefer returning a `bigframes.pandas.DataFrame` that wraps a +`bigframes.bigframes.core.bigframe_node.BigFrameNode`. See `from_bq_data_source` in +`bigframes.core.array_value.ArrayValue`, as an example. + +Exceptions to this are cases where the output schema is likely to evolve or +differ in ways that are difficult to model, such as the `ML.PREDICT` SQL +function, where output columns differ based on the model type and support for +model types are frequently added to BigQuery. In these exceptional cases, the +generated query should run immediately and the returned value should wrap the +results. + +### Argument syntax details + +Arguments in Python can be one of: + +* Positional + * Supported by `*args` in Python, but not recommended. Positional arguments in SQL should map to named positional or keyword arguments in Python. +* Positional or keyword + * Required positional arguments should be positional, just like they are in SQL. +* Keyword-only + * All other arguments should be keyword-only. Use `, * ,` Python syntax to achieve this. + +For optional parameters, use an optional sentinel (see: ) and omit the value from the generated SQL if the user doesn't explicitly provide one. This ensures that an explicit NULL / None value can be passed in. + +``` + +from enum import Enum + +class Default(Enum): + token = 0 + +DEFAULT = Default.token + +def spam(*, ham: list[str] | None | Default = DEFAULT): + op_kwargs = {} + + if ham is not DEFAULT: + op_kwargs['ham'] = "prosciutto" + + ... + +``` + +### Scalar operations types policies + +Many operations output a table expression. For these, the output type is always a DataFrame, regardless of the input types. + +For scalar operations, there are three cases to consider when determining the output types: + + + + + + + + + + + + + + + + + + +
Scalar ops - Input type(s) + Scalar ops - Output type +

When run +without any arguments, it iterates through all yaml files at +`packages/bigframes/scripts/data/sql-functions/**/*.yaml` to generate the code. + +The script also generates a unit test that verifies that the functions have been +included in the `bigframes.bigquery` module, which is important to check, as the +`__init__.py` file requires manual updates. + +## Running the generator + +Since the dependencies for the script differ from that of bigframes +and its test suite, use the self-contained Python script technique described at +https://docs.astral.sh/uv/guides/scripts/ +to automatically manage dependencies using `uv`. Therefore, the header of the +script will look something like: + +```python +#!/usr/bin/env -S uv run --script +# +# /// script +# dependencies = [ +# "jinja2", +# "pyyaml", +# ] +# /// +# +# Copyright 2026 Google LLC +# +# Licensed under the Apache License, Version 2.0 (the "License"); +# ... +``` + +To run the script: + +```bash +cd packages/bigframes +uv run scripts/generate_bigframes_bigquery.py +``` + +To improve reproducibility, we also check in the uv lock file generated by +running `uv lock --script scripts/generate_bigframes_bigquery.py`. + +## Generated code organization + +The `generate_bigframes_bigquery.py` script generates submodules of +`bigframes.bigquery._operations`, with the full path reflecting the organization +of the YAML files. For example, a YAML file at +`packages/bigframes/scripts/data/sql-functions/aead.yaml` corresponds to a +generated Python module at `bigframes.bigquery._operations.aead`. Likewise, +`packages/bigframes/scripts/data/sql-functions/builtins/bit.yaml` corresponds +to the `bigframes.bigquery._operations.builtins.bit` submodule. + +## Generated module implementation + +Each generated module has all functions defined in the YAML file converted to +the equivalent Python definition, including keyword arguments and docstrings. + +### Code generation + +The code will be templated using the jinja2 template engine. This allows +proposed changes to the templated code to be reviewed more easily. + +### Handling optional arguments + +When the user calls a Python function without specifying the optional +argument, that argument is omitted from the SQL text. To allow for explicit +NULL values to be passed in (None in Python), the default value is specified +to be a default sentinel value enum `bigframes.core.sentinels.DEFAULT`. For +example: + +```python +import bigframes.core.sentinels + +def current_date( + time_zone_expression: str | bigframes.core.sentinels.Default = bigframes.core.sentinels.DEFAULT, +): + ... +``` + +### Input and output types + +Refer to the table in +[Contributing to bigframes.bigquery](./bigframes-bigquery-contributing.md). + +### Internal bigframes operator + +Scalar functions should generate an expression using the `GoogleSqlScalarOp`. +This keeps the implementation as scalar SQL functions consistent. + +Aggregate, analytic, and table-valued functions currently require custom ops. As +such, those functions are currently out of scope for this generator. diff --git a/testing/constraints-3.10.txt b/testing/constraints-3.10.txt index b11ab5a88db..1dcdd64baa0 100644 ---
