Bug fixes

  • rel_sql(rel, "{{sql}}") works even on a read-only database (@Tmonster, #138).
  • Avoid R CMD check warning regarding SETLENGTH() and SET_TRUELENGTH() (#145).

duckdb 0.10.1

Features

  • Update to duckdb v0.10.1, see https://github.com/duckdb/duckdb/releases/tag/v0.10.1 for details.
  • Fix shutdown semantics for the driver object created by duckdb(). A database file is closed (and available to be opened from another session) after the last connection that uses this file calls dbDisconnect() . The shutdown argument to dbDisconnect() or the duckdb_shutdown() functions are no longer necessary. Two database connections from the same R session can access the same file concurrently in read-write mode (#124).

Bug fixes

  • Don't run tests that invoke re2 by default (#121, #127).

  • Fix compilation for R 4.0 and R 4.1, regression introduced in v0.10.0. Using librstrtmgr.a from UCRT build of rtools40 (#130).

Internal

  • The C++ core is now vendored commit by commit, once every five minutes. Vendoring stops if R CMD check fails or if a previously unreleased tag is reached.

  • New maintainer: Kirill Müller.

Continuous integration

  • Add rhub2 workflow.

duckdb 0.10.0

Bug fixes

  • dplyr::tbl() works again when a Parquet or CSV file is passed instead of a table name (#38, #91).

  • DBI::dbQuoteIdentifier() correctly quotes identifiers that start with a digit (#67, #92).

  • Align the argument order of dbWriteTable() with the DBI specs (@eitsupi, #43, #49).

Features

  • New tbl_file() and tbl_query() to explicitly access tables and queries as dbplyr lazy tables (#96). The cache argument to tbl() and to the new functions must be named.

  • Initial ALTREP support for LIST logical type (@romainfrancois, #77).

  • Update core to duckdb v0.10.0 (#90).

  • New private rel_to_parquet() to write a relation to parquet (@Tmonster, #46).

Chore
