table_write: Write tabular results into a table buffer or sink

In shard: Deterministic, Zero-Copy Parallel Execution for R

Write tabular results into a table buffer or sink

Description

table_write() is the common write path for shard table outputs:

• For fixed-size outputs, write into a shard_table_buffer using a row selector.

• For variable-size outputs, write into a shard_table_sink using a shard id.

Usage

table_write(target, rows_or_shard_id, data, ...)

Arguments

target	A shard_table_buffer or shard_table_sink.
rows_or_shard_id	For buffers: row selector (idx_range or integer vector). For sinks: shard id (integer).
data	A data.frame or named list matching the schema columns.
...	Reserved for future extensions.

Value

NULL (invisibly).

Examples

s <- schema(x = float64(), y = int32())
tb <- table_buffer(s, nrow = 10L)
table_write(tb, idx_range(1, 5), data.frame(x = rnorm(5), y = 1:5))
