Concatenate one or more Tables


Concatenate one or more Table objects into a single table. This operation does not copy array data, but instead creates new chunked arrays for each column that point at existing array data.


concat_tables(..., unify_schemas = TRUE)



A Table


If TRUE, the schemas of the tables will be first unified with fields of the same name being merged, then each table will be promoted to the unified schema before being concatenated. Otherwise, all tables should have the same schema.


tbl <- arrow_table(name = rownames(mtcars), mtcars)
prius <- arrow_table(name = "Prius", mpg = 58, cyl = 4, disp = 1.8)
combined <- concat_tables(tbl, prius)
