ClickHouse's internal diagnostics grew unbounded (text_log at Trace level and the 1s query profiler -> trace_log accumulated ~160G over months). Add short TTLs to all system *_log tables, cap text_log at warning level, and disable the query profiler in both profiles so trace_log stays empty.

<!-- Keep ClickHouse's internal system log tables from growing unbounded.
|
|
text_log defaults to capturing Trace-level execution messages (Aggregator,
|
|
MergeTreeSequentialSource, ...) which is enormous; cap it at warning. The query
|
|
profiler (trace_log) is disabled in users.xml. Everything gets a short TTL so a
|
|
long-running server can't accumulate hundreds of GB of diagnostics. -->
