Function ReservePhysical

cpp/src/arrow/array/builder_run_end.h:228–230

\brief Ensure that there is enough space allocated to append the indicated number of run without any further reallocation. Overallocation is used in order to minimize the impact of incremental ReservePhysical() calls. Note that additional_capacity is relative to the current number of elements rather than to the current capacity, so calls to Reserve() which are not interspersed with addition of new

  /// \param[in] additional_capacity the number of additional runs
  /// \return Status
  Status ReservePhysical(int64_t additional_capacity) {
    return Reserve(additional_capacity);
  }
