What is datasetjson?

datasetjson rebuilt its object model to track the CDISC Dataset-JSON 1.1 schema.

datasetjson reads and writes CDISC Dataset-JSON, the JSON replacement for SAS transport files in clinical-trial submissions. The package went from a thin reader in 2023 to a redesigned interface in 0.3.0 that targets the 1.1.0 schema, uses yyjsonr as its JSON backend, and exposes column metadata as first-class arguments. Development is contributor-driven inside the Atorus and pharmaverse orbit.

What is pysparklyr?

Posit's Spark Connect bridge keeps adding backends — and now runs tidymodels tuning on the cluster.

pysparklyr is the Python-backed backend that lets sparklyr talk to Spark Connect, Databricks Connect, and now Snowflake, handling the reticulate environment, authentication, and Arrow configuration so R users mostly do not have to. The 0.2.x line has widened it well past a connectivity shim: 0.2.0 brought the Spark 4.0 ML function family and Snowpark Connect, and 0.2.2 added tune_grid_spark() so a tidymodels tuning grid executes inside a Spark Connect cluster. Authentication has become a first-class concern, with Snowflake's native authenticators, connections.toml discovery, and Posit Connect viewer credentials all supported.

datasetjson rebuilt its object model to track the CDISC Dataset-JSON 1.1 schema.

◆ Current state

datasetjson reads and writes CDISC Dataset-JSON, the JSON replacement for SAS transport files in clinical-trial submissions. The package went from a thin reader in 2023 to a redesigned interface in 0.3.0 that targets the 1.1.0 schema, uses yyjsonr as its JSON backend, and exposes column metadata as first-class arguments. Development is contributor-driven inside the Atorus and pharmaverse orbit.

◆ Where it's heading

The package's roadmap is not its own — it tracks a CDISC standard that is still moving, and 0.3.0 is what happens when the standard revises: object model, read and write paths, and JSON backend all changed together. Performance was addressed in the same pass, which matters because submission datasets are large enough that a slow serialiser is a real constraint.

◆ Prediction

The next significant release will most likely follow the next Dataset-JSON schema revision rather than an internal roadmap, given that 0.3.0 was driven entirely by the 1.1.0 update.

3.8

Posit's Spark Connect bridge keeps adding backends — and now runs tidymodels tuning on the cluster.

◆ Current state

pysparklyr is the Python-backed backend that lets sparklyr talk to Spark Connect, Databricks Connect, and now Snowflake, handling the reticulate environment, authentication, and Arrow configuration so R users mostly do not have to. The 0.2.x line has widened it well past a connectivity shim: 0.2.0 brought the Spark 4.0 ML function family and Snowpark Connect, and 0.2.2 added tune_grid_spark() so a tidymodels tuning grid executes inside a Spark Connect cluster. Authentication has become a first-class concern, with Snowflake's native authenticators, connections.toml discovery, and Posit Connect viewer credentials all supported.

◆ Where it's heading

Two directions are running at once. Horizontally, the package is becoming backend-plural — what started as Databricks-and-Spark now covers Snowflake through Snowpark Connect, with credential handling generalized per platform rather than special-cased. Vertically, it is climbing from data manipulation toward modeling: distributed ML functions in 0.2.0, distributed tuning in 0.2.2. A persistent third thread is absorbing upstream churn — Pandas 3.0 conversion, sparklyr 1.9.5 and dbplyr 2.6.0 restructuring the tbl source slot, reticulate's changing environment management.

◆ Prediction

With tuning distributed and the Spark 4.0 ML surface in place, the unfinished edge is the rest of the tidymodels workflow — expect fitting and resampling paths to follow tune_grid_spark() onto the cluster.
