reexecute

Reexecute is a verb that means to execute again or to run something a second time. It is used in various technical domains to describe repeating an instruction, process, or sequence of actions after some change or error. While not a formal term in every context, it appears in documentation, logs, and discussions about software behavior and data workflows.

In software development, reexecution occurs when a program, script, or build task is run again to produce updated output. This can happen after input data changes, configuration edits, or environmental differences. Build systems may reexecute tasks to reflect new dependencies, and test suites may reexecute tests that were affected by code changes or previously failed.

In data analysis and computational notebooks, reexecution refers to running cells, scripts, or pipelines to recompute results. Reexecution supports reproducibility by ensuring that outputs reflect the current code and data. It is common practice to reexecute parts of a workflow after making updates to functions, parameters, or data sources.

In distributed systems and data processing pipelines, reexecution often denotes reprocessing data or replaying events to recover from failures or to validate state after an error. This can involve retrying operations, reapplying transformations, or reloading historical data to achieve consistency.

Notes: The term is sometimes hyphenated as re-execute and is distinct in everyday usage from rerun, which more commonly refers to running something again in non-technical contexts. Usage varies by domain and audience, and reexecution can imply attention to determinism and reproducibility.
