+Statement statistics in the **Statement Fingerprints** table are not accurate when a transaction includes more than 100,000 statements.
+
+At most 100,000 statement statistics can be associated with a single transaction statistic. If a transaction exceeds this limit, CockroachDB automatically flushes buffered statement statistics before the transaction commits. Flushed statement statistics do not have an associated transaction fingerprint ID because the transaction has not yet completed. Because the transaction fingerprint ID cannot be backfilled in these cases, these flushed statement statistics are not included in aggregated results.
