描述

Is your feature request related to a problem? Please describe. Regex features are available in cudf string APIs and nvtext APIs. grep is widely used utility. It would cool to try creating cudfgrep with cudf/nvtext and document the throughput.

Describe the solution you'd like Create cudfgrep utility in our python codebase or a C++ example with libcudf APIs.

Additional context Benchmark it without GDS (most common usecase). Benchmark on GPU in PCIE, and on Grace systems with fast C2C.

研究方向
Examine cuDF string API documentation for regex functions. Look at existing nvtext examples for reference. Study similar utilities in the repository for code structure. Consider implementing a simple prototype in Python first, then possibly in C++. Benchmark on relevant hardware.
