Inspect preserved-object release counters

Returns process-local diagnostics for preserved R objects that native DuckDB catalog metadata could not release immediately because destruction happened off the recorded main R thread. Safe main-thread drain points include rducks_enable(), rducks_release(), rducks_register_scalar_udf(), scalar-UDF execution, and metadata/stat queries.

Usage

rducks_release_stats(con)

Arguments

con

A duckdb_connection.

Value

A one-row data frame with queued, released, failed, and pending counters.

Examples

# \donttest{
db <- duckdb::dbConnect(duckdb::duckdb(config = list(allow_unsigned_extensions = "true")))
rducks_enable(db)
rducks_release_stats(db)
#>   queued released failed pending
#> 1      0        4      0       0
rducks_release(db)
DBI::dbDisconnect(db)
# }
