Add new summary vector metric
rekor_index_storage_latency_summary
to enable tracking latency of entry insertion in the mysql or redis index storage backend.Since the index insertion is non-blocking, the existing API metrics are unable to measure its latency. However, the speed of insertion affects how fast the index is available to query, so it is relevant to rekor's overall performance.
This new metric along with the existing API metrics will help give an clearer picture of rekor's index storage performance.
