Allow to create *MergeTree tables with empty primary key when ORDER BY and PRIMARY KEY not specifiedcreate_token_default_ttl_seconds
The lifetime, in seconds, given to a token created byCREATE TOKEN which does not specify its own VALID UNTIL or VALID FOR clause. The default is 30 minutes, so a token that is not asked to live longer is short-lived.
Possible values:
- Positive integer — the token expires this many seconds after it is created.
- 0 — a token without an explicit clause never expires.
VALID UNTIL or VALID FOR clause of the query always wins, including VALID UNTIL 'infinity', which creates a token that never expires regardless of this setting.
