Hi,
I’m in need of some help to implement concatenation of two or more cudf::Table/arrow::Table by timestamp using libcudf c++.

  • New columns should be added if isn’t common in both. This is similar to merging DataFrame by index in pandas.
  • Null values should be filled during merge if no data point exist at specific timestamp for any particular table.

Best,
Dom
