Code review comment: The most risky bug in this code is: Inappropriate use of `contains` method for `reason` comparison which can lead to unexpected behavior when the reason string contains any of the substrings in `MV_NO_AUTOMATIC_ACTIVE_REASONS`.  You can modify the code like this: ```java // Change this code block: if (MV_NO_AUTOMATIC_ACTIVE_REASONS.stream().anyMatch(x -> x.contains(reason))) {     return; }  // To this: if (MV_NO_AUTOMATIC_ACTIVE_REASONS.contains(reason)) {     return; } ```

Code before review:
public static void tryToActivate(MaterializedView mv, boolean checkGracePeriod) {
String reason = mv.getInactiveReason();
if (mv.isActive() || AlterJobMgr.MANUAL_INACTIVE_MV_REASON.equalsIgnoreCase(reason)) {
return;
}
if (MV_NO_AUTOMATIC_ACTIVE_REASONS.stream().anyMatch(x -> x.contains(reason))) {
return;
}
long dbId = mv.getDbId();
Optional<String> dbName = GlobalStateMgr.getCurrentState().mayGetDb(dbId).map(Database::getFullName);
if (!dbName.isPresent()) {
LOG.warn("[MVActiveChecker] cannot activate MV {} since database {} not found", mv.getName(), dbId);
return;
}
MvActiveInfo activeInfo = MV_ACTIVE_INFO.get(mv.getMvId());
if (checkGracePeriod && activeInfo != null && activeInfo.isInGracePeriod()) {
LOG.warn("[MVActiveChecker] skip active MV {} since it's in grace-period", mv);
return;
}
boolean activeOk = false;
String mvFullName =
new TableName(InternalCatalog.DEFAULT_INTERNAL_CATALOG_NAME, dbName.get(), mv.getName()).toString();
String sql = String.format("ALTER MATERIALIZED VIEW %s active", mvFullName);
LOG.info("[MVActiveChecker] Start to activate MV {} because of its inactive reason: {}", mvFullName, reason);
try {
ConnectContext connect = StatisticUtils.buildConnectContext();
connect.setStatisticsContext(false);
connect.setDatabase(dbName.get());
connect.executeSql(sql);
if (mv.isActive()) {
activeOk = true;
LOG.info("[MVActiveChecker] activate MV {} successfully", mvFullName);
} else {
LOG.warn("[MVActiveChecker] activate MV {} failed", mvFullName);
}
} catch (Exception e) {
LOG.warn("[MVActiveChecker] activate MV {} failed", mvFullName, e);
} finally {
ConnectContext.remove();
}
if (activeOk) {
MV_ACTIVE_INFO.remove(mv.getMvId());
} else {
if (activeInfo != null) {
activeInfo.next();
} else {
MV_ACTIVE_INFO.put(mv.getMvId(), MvActiveInfo.firstFailure());
}
}
}
