Debug the ADBC chunk fetch path for a lazy dbplyr table

Fetches Arrow chunks one at a time using the experimental ADBC path and records where failures occur. This is intended for diagnosing driver or result-set issues without writing a Parquet file.

Usage

tbl_to_pq_debug(tbl, max_chunks = Inf)

Arguments

tbl

A lazy table backed by dbplyr.

max_chunks

Maximum number of chunks to inspect. Default is Inf.

Value

A data frame with one row per attempted chunk.

Examples

if (FALSE) { # \dontrun{
# Requires a PostgreSQL connection and the ADBC driver installed
con <- DBI::dbConnect(RPostgres::Postgres())
qry <- dplyr::tbl(con, DBI::Id(schema = "crsp", table = "dsi"))
tbl_to_pq_debug(qry, max_chunks = 3L)
DBI::dbDisconnect(con)
} # }
