Write VCF/BCF to Arrow IPC format — vcf_to_arrow

Converts a VCF/BCF file to Arrow IPC stream format for efficient storage and interoperability with Arrow-compatible tools. Uses nanoarrow's native IPC writer for streaming output.

Usage

vcf_to_arrow_ipc(input_vcf, output_ipc, ...)

Arguments

input_vcf: Path to input VCF or BCF file
output_ipc: Path for output Arrow IPC file (typically .arrows extension)
...: Additional arguments passed to vcf_open_arrow

Value

Invisibly returns the output path

Examples

if (FALSE) { # \dontrun{
vcf_to_arrow_ipc("variants.vcf.gz", "variants.arrows")

# Read back with nanoarrow
stream <- nanoarrow::read_nanoarrow("variants.arrows")
df <- as.data.frame(stream)

# Or query with DuckDB
library(duckdb)
con <- dbConnect(duckdb())
dbGetQuery(con, "SELECT * FROM 'variants.arrows' LIMIT 10")
} # }
