Upload

class Upload

Uploads are the interface for bringing data into Redivis. They are associated with a particular table, and can be created on any table belonging to an unreleased version of a dataset. Multiple uploads can be added to a table, in which case they are "stacked" together (equivalent to a union join, with mixed schemas supported).

Constructors

table$upload(upload_name)	Construct a reference to an upload based on its name.

Examples

Upload tabular file

table <- dataset$table("table_name")

upload <- table$upload()$create(
    "./data.csv",           # Path to file, data.frame, raw vector, etc
    type="delimited",       # Inferred from file extension if not provided
    remove_on_fail=True,    # Remove the upload if a failure occurs
    wait_for_finish=True,   # Wait for the upload to finish processing
    raise_on_fail=True      # Raise an error on failure
)

Upload multiple files

dataset <- redivis$user("user_name")$dataset("dataset_name", version="next")
table <- dataset$table("table_name")

dir_path <- "/path/to/data/directory"

for (filename in list.files(dir_path)){
    upload <- table$upload()$create(content=base::file.path(dir_path, filename))
}
