The problem here is that there is a tiny race window between DETACH
and OPTIMIZE.

DETACH cancel merges, and checks that there no merges for parts
currently under lock, and later changes the state of parts. After it
allows merges.

However OPTIMIZE get parts for processing under lock and only when it
starts writing temporary part it checks that merges are not canceled.

So suppose the following scenario:

      T#OPTIMIZE                       T#DETACH

                                       - cancel merges
                                           - lock
                                             - check that no merges are in progress
                                           - unlock
    - lock
      - get parts

          *<--Here, state of the parts are not changed yet,
              and lock is not held,
              so OPTIMIZE may (and will) get those parts. -->*

      - write temporary part
        - check merges not canceled
    - unlock
                                           - change the parts state
                                       - allows merges

Plus this patch will also fail merges earlier in case of concurrent
DETACH.

1062d0ec91 Distinguish KILL MUTATION for different tables.
Before this patch KILL MUTATION marks mutation as canceled just by name
(and part numbers) so if you have multiple tables with the same part
name, then killing mutation for one table, will mark it as killed for
another too.

Fix this by comparing StorageID too (it is better to use StorageID over
database/table to avoid ambiguity by using UUIDs for comparing).

Here is a failure of the 01414_freeze_does_not_prevent_alters on CI [1].

Projections
TODO (suggested by Nikolai)

1. Build query plan fro current query (inside storage::read) up to WithMergableState
2. Check, that plan is simple enough: Aggregating - Expression - Filter - ReadFromStorage (or simplier)
3. Check, that filter is the same as filter in projection, and also expression calculates the same aggregation keys as in projection
4. Return WithMergableState if projection applies

3 will be easier to do with ActionsDAG, cause it sees all functions, and dependencies are direct (but it is possible with ExpressionActions also)

Also need to figure out how prewhere works for projections, and
row_filter_policies.

867ddab00a StorageMergeTree::selectPartsToMutate: Reduce the amount of logs when busy
In a busy system without enough threads to process mutations at the moment,
you would get a log message per data part with pending mutations, which in
some extreme cases could be dozens per call.

70ea507dae OPTIMIZE DEDUPLICATE BY columns
Extended OPTIMIZE ... DEDUPLICATE syntax to allow explicit (or implicit with asterisk/column transformers) list of columns to check for duplicates on.

Following syntax variants are now supported:

OPTIMIZE TABLE table DEDUPLICATE; -- the old one
OPTIMIZE TABLE table DEDUPLICATE BY *;
OPTIMIZE TABLE table DEDUPLICATE BY * EXCEPT colX;
OPTIMIZE TABLE table DEDUPLICATE BY * EXCEPT (colX, colY);
OPTIMIZE TABLE table DEDUPLICATE BY col1,col2,col3;
OPTIMIZE TABLE table DEDUPLICATE BY COLUMNS('column-matched-by-regex');
OPTIMIZE TABLE table DEDUPLICATE BY COLUMNS('column-matched-by-regex') EXCEPT colX;
OPTIMIZE TABLE table DEDUPLICATE BY COLUMNS('column-matched-by-regex') EXCEPT (colX, colY);

Note that * behaves just like in SELECT: MATERIALIZED, and ALIAS columns are not used for expansion.
Also, it is an error to specify empty list of columns, or write an expression that results in an empty list of columns, or deduplicate by an ALIAS column.
Column transformers other than EXCEPT are not supported.
