@robertmaynard I'm good with merging this but I have one question. I'm not sure if we also need tests in cpp/tests/streams/ that test non-default streams. See example: https://github.com/rapidsai/cudf/pull/12090/files#diff-5516770bab1d0040cbe3186249cc0bf185bb8ae92702abe97b2beb44fe6b21b6.

Looking at the other stream tests, I do need to refactor my changes and move the tests::get_default_stream() version to a new file under cpp/tests/streams

    Add patch for incorrect cuco noexcept clauses (rapidsai#16077)

    [cuco previously marked a number of methods as noexcept that can in fact
    throw exceptions](NVIDIA/cuCollections#510).
    This causes problems for cudf functions that call these methods. The
    issue [was fixed in cuco
    upstream](NVIDIA/cuCollections#511), but we
    cannot easily update to the latest commit of cuco, especially in a patch
    fix for 24.06. This PR instead adds a rapids-cmake patch for the cuco
    clone to address this issue. The patch may be removed once we update to
    a commit of cuco that contains the necessary fix.

    Implement handlers for series literal in cudf-polars (rapidsai#16113)

    A query plan can contain a "literal" polars Series. Often, for example, when calling a contains-like function. To translate these, introduce a new `LiteralColumn` node to capture the concept and add an evaluation rule (converting from arrow).

    Since list-dtype Series need the same casting treatment as in dataframe scan case, factor the casting out into a utility, and take the opportunity to handled casting of nested lists correctly.

    Update implementations to build with the latest cuco (rapidsai#15938)

    This PR updates existing libcudf to accommodate a cuco breaking change introduced in NVIDIA/cuCollections#479. It helps avoid breaking cudf when bumping the cuco version in `rapids-cmake`.

    Redundant equal/hash overloads will be removed once the version bump is done on the `rapids-cmake` end.

    Use size_t to allow large conditional joins (rapidsai#16127)

    The conditional join kernels were using `cudf::size_type` where `std::size_t` was needed. This PR fixes that bug, which caused `cudaErrorIllegalAddress` as shown in rapidsai#16115. This closes rapidsai#16115.

    I did not add tests because we typically do not test very large workloads. However, I committed the test and reverted it in this PR, so there is a record of my validation code.

    Move common string utilities to public api (rapidsai#16070)

    As part of rapidsai#15982 a subset of the strings utility functions have been identified as being worth expsosing as part of the cudf public API.

    The `create_string_vector_from_column`, `get_offset64_threshold`, and `is_large_strings_enabled` are now made part of the public `cudf::strings` api.

    Templatization of fixed-width parquet decoding kernels. (rapidsai#15911)

    This PR merges all of the fixed-width parquet decoding kernels into a single templatized kernel that can be selectively instantiated with desired features (dictionary/no-dictionary, nested/non-nested, etc).  It also adds support for (non-list) nested columns in this path. So structs do not have to use the much slower general decode kernel any more.

    A new benchmark was added specific to structs containing only fixed width columns.  I added this because the performance improvement is fairly high (+20%) but we don't see it in the normal struct benchmarks because they include (and are dominated by) string decode times.  The new benchmark shows:

    Before this PR:
    ```
    | data_type |    io_type    | cardinality | run_length | bytes_per_second | peak_memory_usage | encoded_file_size |
    |-----------|---------------|-------------|------------|------------------|-------------------|-------------------|
    |    STRUCT | DEVICE_BUFFER |           0 |          1 |      21071216823 |         1.047 GiB |       511.675 MiB |
    |    STRUCT | DEVICE_BUFFER |        1000 |          1 |      18974392387 |       821.312 MiB |       128.884 MiB |
    |    STRUCT | DEVICE_BUFFER |           0 |         32 |      20429356824 |      621.787 MiB  |        28.141 MiB |
    |    STRUCT | DEVICE_BUFFER |        1000 |         32 |      20572327813 |       598.421 MiB |        16.475 MiB |
    ```

    After this PR:

    ```
    | data_type |    io_type    | cardinality | run_length | bytes_per_second | peak_memory_usage | encoded_file_size |
    |-----------|---------------|-------------|------------|------------------|-------------------|-------------------|
    |    STRUCT | DEVICE_BUFFER |           0 |          1 |      25805996399 |         1.047 GiB |       511.675 MiB |
    |    STRUCT | DEVICE_BUFFER |        1000 |          1 |      22422306660 |       821.312 MiB |       128.884 MiB |
    |    STRUCT | DEVICE_BUFFER |           0 |         32 |      24460694014 |       621.787 MiB |        28.141 MiB |
    |    STRUCT | DEVICE_BUFFER |        1000 |         32 |      24674861214 |       598.421 MiB |        16.475 MiB |
    ```

    Split-page decoding for fixed-width types + structs are also going through this new path. New test added.

    This brings us closer to eliminating the "general" kernel.  The only things left that run through it are lists and booleans.

    This is PR 1 of 2, with the followup moving a lot of code around.  At this point, I think it makes sense to start consolidating our files a bit.

    I also left some breadcrumbs (a few small commented out code blocks) in the core kernel `gpuDecodePageDataGeneric` for the next step of adding list support. They can be removed if people don't like them.

    Make binary operators work between fixed-point and floating args (rapidsai#16116)

    Some of the binary operators in cuDF don't work between fixed_point and floating-point numbers after [this earlier PR](rapidsai#15438) removed the ability to construct and implicitly cast fixed_point numbers from floating point numbers. This PR restores that functionality by detecting and performing the necessary explicit casts, and adds tests for the supported operators.

    Note that the `binary_op_has_common_type` code is modeled after `has_common_type` found in traits.hpp.

    The `cudf.Index` constructor will shallow copy a `cudf.Index` input. Sometimes, we just need to make sure an input is a `cudf.Index`, so created `ensure_index` (pandas has something similar) so we don't shallow copy these inputs unnecessarily

    Example
    ```python
    import cudf
    from cudf.utils.performance_tracking import print_memory_report

    cudf.set_option("memory_profiling", True)

    df1 = cudf.DataFrame({"a": [1, 2, 3]})
    df2 = cudf.DataFrame({"a": [2, 2, 3]})
    df3 = df1.merge(df2)

Date:   Thu Jun 27 21:33:29 2024 +0100

    Finish implementation of cudf-polars boolean function handlers (rapidsai#16098)

    The missing nodes were `is_in`, `not` (both easy), `is_finite` and `is_infinite` (obtained by translating to `contains` calls).

    While here, remove the implementation of `IsBetween` and just translate to an expression with binary operations. This removes the need for special-casing scalar arguments to `IsBetween` and reproducing the code for binop evaluation.

    Use Arrow C Data Interface functions for Python interop (rapidsai#15904)

    This PR replaces the internals of `from_arrow` in pylibcudf with an implementation that uses the [Arrow C Data Interface](https://arrow.apache.org/docs/format/CDataInterface.html) using the [Python Capsule interface](https://arrow.apache.org/docs/format/CDataInterface/PyCapsuleInterface.html). This allows us to decouple our Python builds from using pyarrow Cython (partially, we haven't replaced the `to_arrow` conversion yet) and it will also allow us to support any other Python package that is a producer of the data interface.

    To support the above functionality, the following additional changes were needed in this PR:
    - Added the ability to produce cudf tables from `ArrowArrayStream` objects since that is what `pyarrow.Table` produces. This function is a simple wrapper around the existing `from_arrrow(ArrowArray)` API.
    - Added support for the large strings type, for which support has improved throughout cudf since the `from_arrow_host` API was added and for which we now require a basic overload for tests to pass. I did not add corresponding support for `from_arrow_device` to avoid ballooning the scope of this PR, so that work can be done in a follow-up.
    - Proper handling of `type_id::EMPTY` in concatenate because the most natural implementation of the ArrowArrayStream processing is to run `from_arrow` on each chunk and then concatenate the outputs, and from the Python side we can produce chunks of all null arrays from arrow.

    pandas allows objects to `astype` to any other type if the object is empty. The PR mirrors that behavior for cudf.

    Add patch for incorrect cuco noexcept clauses (rapidsai#16077)

    [cuco previously marked a number of methods as noexcept that can in fact
    throw exceptions](NVIDIA/cuCollections#510).
    This causes problems for cudf functions that call these methods. The
    issue [was fixed in cuco
    upstream](NVIDIA/cuCollections#511), but we
    cannot easily update to the latest commit of cuco, especially in a patch
    fix for 24.06. This PR instead adds a rapids-cmake patch for the cuco
    clone to address this issue. The patch may be removed once we update to
    a commit of cuco that contains the necessary fix.

    Implement handlers for series literal in cudf-polars (rapidsai#16113)

    A query plan can contain a "literal" polars Series. Often, for example, when calling a contains-like function. To translate these, introduce a new `LiteralColumn` node to capture the concept and add an evaluation rule (converting from arrow).

    Since list-dtype Series need the same casting treatment as in dataframe scan case, factor the casting out into a utility, and take the opportunity to handled casting of nested lists correctly.

    Use size_t to allow large conditional joins (rapidsai#16127)

    The conditional join kernels were using `cudf::size_type` where `std::size_t` was needed. This PR fixes that bug, which caused `cudaErrorIllegalAddress` as shown in rapidsai#16115. This closes rapidsai#16115.

    I did not add tests because we typically do not test very large workloads. However, I committed the test and reverted it in this PR, so there is a record of my validation code.

    Templatization of fixed-width parquet decoding kernels. (rapidsai#15911)

    This PR merges all of the fixed-width parquet decoding kernels into a single templatized kernel that can be selectively instantiated with desired features (dictionary/no-dictionary, nested/non-nested, etc).  It also adds support for (non-list) nested columns in this path. So structs do not have to use the much slower general decode kernel any more.

    A new benchmark was added specific to structs containing only fixed width columns.  I added this because the performance improvement is fairly high (+20%) but we don't see it in the normal struct benchmarks because they include (and are dominated by) string decode times.  The new benchmark shows:

    Split-page decoding for fixed-width types + structs are also going through this new path. New test added.

    This brings us closer to eliminating the "general" kernel.  The only things left that run through it are lists and booleans.

    This is PR 1 of 2, with the followup moving a lot of code around.  At this point, I think it makes sense to start consolidating our files a bit.

    I also left some breadcrumbs (a few small commented out code blocks) in the core kernel `gpuDecodePageDataGeneric` for the next step of adding list support. They can be removed if people don't like them.

    Make binary operators work between fixed-point and floating args (rapidsai#16116)

    Some of the binary operators in cuDF don't work between fixed_point and floating-point numbers after [this earlier PR](rapidsai#15438) removed the ability to construct and implicitly cast fixed_point numbers from floating point numbers. This PR restores that functionality by detecting and performing the necessary explicit casts, and adds tests for the supported operators.

    Note that the `binary_op_has_common_type` code is modeled after `has_common_type` found in traits.hpp.

    This closes [issue 16090](rapidsai#16090)

    Add ensure_index to not unnecessarily shallow copy cudf.Index (rapidsai#16117)

    The `cudf.Index` constructor will shallow copy a `cudf.Index` input. Sometimes, we just need to make sure an input is a `cudf.Index`, so created `ensure_index` (pandas has something similar) so we don't shallow copy these inputs unnecessarily

    Memory Profiling (rapidsai#15866)

    Use [RMM's new memory profiler](rapidsai/rmm#1563) to profile all functions already decorated with `_cudf_nvtx_annotate`.

    Example
    ```python
    import cudf
    from cudf.utils.performance_tracking import print_memory_report

    cudf.set_option("memory_profiling", True)

    df1 = cudf.DataFrame({"a": [1, 2, 3]})
    df2 = cudf.DataFrame({"a": [2, 2, 3]})
    df3 = df1.merge(df2)

    print_memory_report()
    ```

    Output:

    Finish implementation of cudf-polars boolean function handlers (rapidsai#16098)

    The missing nodes were `is_in`, `not` (both easy), `is_finite` and `is_infinite` (obtained by translating to `contains` calls).

    While here, remove the implementation of `IsBetween` and just translate to an expression with binary operations. This removes the need for special-casing scalar arguments to `IsBetween` and reproducing the code for binop evaluation.
