odbc vs rappdirs
A side-by-side editorial comparison of odbc and rappdirs — release velocity, themes, recent moves, and the top alternatives to consider.
odbc vs rappdirs: at a glance
What is odbc?
odbc keeps turning into an authentication broker with a database driver attached.
odbc is DBI's ODBC backend, and the releases in view are dominated by three vendors. Databricks, Snowflake and Redshift each got a dedicated connection helper, and the work since has been almost entirely about credentials: OAuth, viewer-based identity on Posit Connect, service principals, workload identity federation, private keys passed from memory. The plain driver work — DATETIMEOFFSET on SQL Server, DB2 XML, Oracle date writes, an interrupt that no longer crashes — runs underneath in a steady stream of point releases.
What is rappdirs?
Load-bearing across CRAN, and untouched since January 2021.
rappdirs answers one question — where does an application put its data, cache and config on this operating system — and it has answered it the same way since 2014. The last release was 0.3.3 in January 2021, a revert of accidental vectorisation introduced four days earlier. The only substantive change in the package's visible history is 0.3.2 teaching user_data_dir(), use_cache_dir() and use_config_dir() to respect the R_USER_DATA_DIR, R_USER_CACHE_DIR and R_USER_CONFIG_DIR environment variables.

odbc keeps turning into an authentication broker with a database driver attached.
◆ Current state
odbc is DBI's ODBC backend, and the releases in view are dominated by three vendors. Databricks, Snowflake and Redshift each got a dedicated connection helper, and the work since has been almost entirely about credentials: OAuth, viewer-based identity on Posit Connect, service principals, workload identity federation, private keys passed from memory. The plain driver work — DATETIMEOFFSET on SQL Server, DB2 XML, Oracle date writes, an interrupt that no longer crashes — runs underneath in a steady stream of point releases.
◆ Where it's heading
The centre of the package has moved from talking to a database to proving who you are to a warehouse. Version 1.7.0 makes that explicit by handing Snowflake connection resolution to the snowflakeauth package so odbc reads the vendor's own connections.toml rather than defining its own parameter set. That is a pattern worth watching: as each warehouse standardises its config across CLI, Python and R, odbc's job shifts from inventing an interface to conforming to one.
◆ Prediction
Expect Databricks to get the same treatment Snowflake just received — configuration resolved from the vendor's own config files rather than from odbc arguments — and expect the deprecated odbcConnection* functions to be removed outright.
rappdirs
0.0DEVOPS
Load-bearing across CRAN, and untouched since January 2021.
◆ Current state
rappdirs answers one question — where does an application put its data, cache and config on this operating system — and it has answered it the same way since 2014. The last release was 0.3.3 in January 2021, a revert of accidental vectorisation introduced four days earlier. The only substantive change in the package's visible history is 0.3.2 teaching user_data_dir(), use_cache_dir() and use_config_dir() to respect the R_USER_DATA_DIR, R_USER_CACHE_DIR and R_USER_CONFIG_DIR environment variables.
◆ Where it's heading
Nothing is heading anywhere, and that is the finding. A port of a Python utility with no open direction, four releases in eleven years, and a dependency position underneath a large share of CRAN packages that need a cache directory. The 0.3.2 and 0.3.3 pair is instructive: a real improvement shipped alongside an accidental behaviour change that had to be reverted within the week, and then silence.
◆ Prediction
The entries give no basis for predicting a next release; on eleven years of evidence the most likely next change is a CRAN-mandated check fix rather than anything user-facing.
