duckdbfs 0.0.7

• The default cached_connection() helper will configure a temporary storage location by default. It also now supports all options supported by duckdb::duckdb() for connection creation.
• New as_dataset() utility copies a local in-memory data.frame into the connection.

duckdbfs 0.0.6

• bugfix: reading from local disk recursively no longer requires manual **. Also, trying to read from an existing local file won’t try and append recursive search even when given the default recursive=TRUE option.
• bugfix: open_dataset() uses random table name by default, avoid naming collisions.

duckdbfs 0.0.5

• bugfix write_dataset() no longer adds ** into paths when writing some partitions.
• Protect from unsupported table names generated from file names that start with a digit, fixes #21.

duckdbfs 0.0.4

• open_dataset() gains the ability to read spatial vector data formats (objects read by sf) using format="sf"

• default geometry column in to_sf() is now termed geom, to match the default used in duckdb’s st_read() function.

• open_dataset() now tries to guess the data format instead of defaulting to parquet when no format is explicitly provided.

• a new function, spatial_join(), allows a variety of spatial joins.
  

• a new function, st_read_meta(), exposes the spatial metadata of remote spatial objects.

• new helper function, as_view(), creates a temporary view of a query.

duckdbfs 0.0.3

• write_dataset() now understands lazy queries, not just lazy tables.

duckdbfs 0.0.2

• duckdbfs now has spatial data query support! Users can leverage spatial data operations like st_distance() and st_area() and request return values as sf objects. Supports network-based access too. See README.md

• Added write_dataset() which can write to (potentially partitioned) parquet to local directories or remote (S3) buckets.

• The S3 interface supports arrow-compatible URI notation:

  • Alternate endpoints can now be passed like so s3://userid:secret_token@bucket-name?endpoint_override=data.ecoforecast.org
  • Users can omit the use of * (match any file) or ** (recursive search) and just supply a path. Recursive search is then assumed automatically. Note: unlike arrow, this still supports the use of globs (*) elsewhere in the path, e.g. s3://bucket/*/path

• duckdb_s3_config gains argument anonymous allowing users to ignore existing AWS keys that may be set in environmental variables or AWS configuration files. This can also be passed as the username position in URI notation, e.g. s3://anonymous@bucket_name.

• open_dataset drops use of endpoint as an argument. Instead, alternative S3 endpoints can be set either by using the URI query notation or calling duckdb_s3_config() first. Additionally, any arguments to duckdb_s3_config(), including s3_endpoint, can now be passed to open_dataset through the .... Note these settings will override any set by the URI notation.

duckdbfs 0.0.1

• Initial release to CRAN

These binaries (installable software) and packages are in development.
They may not be fully stable and should be used with caution. We make no claims about them.
