High-Performance Open-Source Archive
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.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.encrypt_value() and decrypt_value()
functions, respectively, to encrypt and decrypt string using RSA..env) reader from
read_env() to read_dot_env().read_rcdf() and get_rcdf_metadata().get_attr() to retrieve attribute/s from RCDF
object.read_parquet_tbl() to read encrypted Parquet file
and return as lazy data from DuckDB connection.pre_collect argument in
read_rcdf()merge_rcdf() function to combine multiple RCDF
files with different encryption keys into one.read_rcdf() to allow reading of multiple RCDF
file with different encryption keys.pre_collect argument to read_rcdf()
to allow lazy loading the RCDF object.NEWS.md file to track changes to the
