This number raises concerns about performance, suggesting that such an operation could be slow. However, when evaluating the computational complexity of operating on two sets of 10,000 pairs of int64_t, an $O(n)$ complexity appears manageable. The process might require an additional log(n) factor to efficiently combine the clusters.

In order to optimize this process, it's advisable to devise a clever method for generating the new set of clusters. This should ideally be accomplished by using the original set along with the conflicted and new transactions as a base, rather than constructing the new set from scratch. Utilizing the existing information to influence the generation of new clusters can lead to a more efficient update process and mitigate the potential slowdown associated with handling a large number of transactions and clusters.
