Preempted insert operations cause very poor performance overall

Description

fixed Constraint violations when running insert jobs with preemption enabled, but the checks add too much overhead on large insert jobs with lots of preempted tasks. We need to implement a more efficient mechanism that doesn't compromise the system's performance.

Test Plan

[Template: please modify accordingly]
Testing considerations and plan:
1. User impact/behavior changes (e.g., error message change)
2. Variation consideration (e.g., Count/Sum/Max/Min/Avg, Parquet/ORC/AVRO formats)
3. Platform consideration (Cloudera/HDP/MapR, kerberos/ldap, HBase/Spark versions)
4. Upgrade/backdown compatibility (e.g., data dictionary changes)
5. Client connectivity impact (JDBC/ODBC)
6. Configuration changes needed
7. Performance expectations
