do(.data, ..., .chunk_size = 10000L)
Arguments
.data

a tbl

...

Expressions to apply to each group. If named, results will be stored in a new column. If unnamed, should return a data frame. You can use . to refer to the current group. You can not mix named and unnamed arguments.

.chunk_size

The size of each chunk to pull into R. If this number is too big, the process will be slow because R has to allocate and free a lot of memory. If it's too small, it will be slow, because of the overhead of talking to the database.
