rcdf 0.1.6
Security fixes
generate_pw(): switched from Mersenne Twister to a
cryptographically secure RNG (openssl::rand_bytes).write_parquet(): DuckDB errors no longer leak raw
encryption key material in messages.write_rcdf_parquet(): plaintext temp table is now
always removed after a shared-connection write.write_rcdf_as(): replaced eval(parse())
dispatch with a safe named-list of function references.hex_to_raw(): added strict input validation (type,
length, character set).
write_parquet() / write_rcdf_parquet():
removed httpfs overhead; shared DuckDB connection across
writes; default compression changed to zstd.read_rcdf(): new lazy = TRUE option for
DuckDB-backed lazy reads; n_threads for parallel I/O;
duplicate PRAGMA calls deduplicated per connection.add_metadata(): label assignment vectorised with batch
update.open_duckdb_connection(): no longer forces
single-threaded mode.
Bug fixes
collect.rcdf_tbl_db(): fixed infinite-dispatch
recursion; NULL metadata no longer causes an error.read_parquet(): unencrypted early-return path now
correctly applies metadata and
as_arrow_table.normalize_key_value(): hex keys no longer misidentified
as base-64.
Documentation
- Main vignette rewritten for general/non-technical users with a
step-by-step workflow.
- Merging vignette completed and fixed.
rcdf 0.1.5
Feature and update
- Added
encrypt_value() and decrypt_value()
functions, respectively, to encrypt and decrypt string using RSA.
- Changed “dot env” (
.env) reader from
read_env() to read_dot_env().
Bug fix
- Fixed bugs not returning metadata attributes using either
read_rcdf() and get_rcdf_metadata().
rcdf 0.1.4
Features
- Added
get_attr() to retrieve attribute/s from RCDF
object.
- Added
read_parquet_tbl() to read encrypted Parquet file
and return as lazy data from DuckDB connection.
Breaking change
- Removed
pre_collect argument in
read_rcdf()
Enhancements
- Improved SQL query string interpolation for all DuckDB related
codes.
rcdf 0.1.3
- Added
merge_rcdf() function to combine multiple RCDF
files with different encryption keys into one.
- Updated
read_rcdf() to allow reading of multiple RCDF
file with different encryption keys.
- Added
pre_collect argument to read_rcdf()
to allow lazy loading the RCDF object.
rcdf 0.1.2
rcdf 0.1.1
- Added a
NEWS.md file to track changes to the
package.
