Reset Rducks scalar-UDF counters — rducks_reset_udf

Resets native per-scalar-UDF diagnostic counters without unregistering any DuckDB catalog function. Current liveness gauges such as pending/in-flight counts are preserved; their max fields are reset to the current values.

Usage

rducks_reset_udf_counters(con, name = NULL)

Arguments

con: A duckdb_connection with Rducks enabled.
name: Optional SQL scalar-UDF function name registered with rducks_register_scalar_udf(). If NULL, reset counters for all native Rducks scalar UDFs in the database runtime.

Value

Invisibly TRUE on success.

Examples

# \donttest{
db <- duckdb::dbConnect(duckdb::duckdb(config = list(allow_unsigned_extensions = "true")))
rducks_enable(db, threads = "single")
rducks_register_scalar_udf(db, "my_fn", function(x) x + 1L,
  args = list(INTEGER), returns = INTEGER)
#> <rducks_scalar_udf_registration>
#>   registered:      yes
#>   name:            my_fn
#>   evaluation_mode: scalar
#>   plan:            arrow_r+serial
#>   signature:       my_fn(INTEGER) -> INTEGER
rducks_reset_udf_counters(db, "my_fn")
