Hi Ryan, I believe the compute function "binary_join_element_wise" in the Arrow C++ library does just this: https://arrow.apache.org/docs/cpp/compute.html#string-joining
I believe you can call this function in PyArrow following the same pattern described here: https://arrow.apache.org/docs/python/compute.html#standard-compute-functions Ian On Mon, Sep 26, 2022 at 5:26 PM Ryan Kuhns <[email protected]> wrote: > > Hi, > > I’ve started using Apache Arrow via pyarrow. > > One area I’ve struggled is the ability to create a new column that is a > concatenation of other string columns. > > The existing string concatenation compute functions don’t appear to work for > the case I’m describing. > > Are there any plans to create a compute function that accepts arrays of > strings and returns an array that has concatenated the input arrays > element-wise? > > Or is there an efficient way I could use the existing functionality to > accomplish this? > > Thanks in advance for the help! > > Ryan
