Problem

WiredTiger WT-18492 removes the verbose=tiered choice and WT_VERB_TIERED. The server still maps that category in wiredtiger_util.cpp: a case WT_VERB_TIERED: and "tiered" in generateWTVerboseConfiguration(), which is always passed to wiredtiger_open / reconfigure.

Vendoring WT-18492 without this change will not compile (missing WT_VERB_TIERED). Leaving only the string would fail engine open (tiered is no longer a permitted verbose choice).

This must land on master before that WiredTiger change is vendored. It is forward-compatible while WT still accepts tiered.

Change* Delete case WT_VERB_TIERED: in getWTLogComponent().

• Delete {{ {kWiredTigerTiered, "tiered"}

  }} from the verbose component map.

• Remove kWiredTigerTiered / wtTiered from log_component.h if nothing else references it.

Do not vendor WiredTiger in this ticket.

Test

bazel run //src/mongo/db/storage/wiredtiger:wiredtiger_util_test (or the existing target for that file). Confirm generated verbose config no longer contains tiered:.
