-- ReviewRemediationIndexes (2026-10-22). Run with QUOTED_IDENTIFIER ON (sqlcmd -I, or keep
|
|
-- this header): AuditLog has persisted computed columns / filtered indexes and SQL Server
|
|
-- raises error 1934 otherwise.
|
|
-- AuditLog is monthly-partitioned; the two AuditLog indexes are created ON
|
|
-- ps_AuditLog_Month(OccurredAtUtc) so they stay partition-aligned and the partition-switch
|
|
-- purge keeps working. Building them scans the whole AuditLog: on a large production table
|
|
-- run in a quiet window, and on Enterprise edition add WITH (ONLINE = ON) to the two
|
|
-- AuditLog CREATE INDEX statements (and to the AuditLogEntries ones if that table is large).
