98e3a99a88 Do not catch exceptions during final flush in writers destructors 
Since this hides real problems, since destructor does final flush and if
it fails, then data will be lost.

One of such examples if MEMORY_LIMIT_EXCEEDED exception, so lock
exceptions from destructors, by using
MemoryTracker::LockExceptionInThread to block these exception, and allow
others (so std::terminate will be called, since this is c++11 with
noexcept for destructors by default).

Here is an example, that leads to empty block in the distributed batch:

921518db0a CLICKHOUSE-606: query deduplication based on parts' UUID 
* add the query data deduplication excluding duplicated parts in MergeTree family engines.

query deduplication is based on parts' UUID which should be enabled first with merge_tree setting
assign_part_uuids=1

allow_experimental_query_deduplication setting is to enable part deduplication, default ot false.

data part UUID is a mechanism of giving a data part a unique identifier.
Having UUID and deduplication mechanism provides a potential of moving parts
between shards preserving data consistency on a read path:
duplicated UUIDs will cause root executor to retry query against on of the replica explicitly
asking to exclude encountered duplicated fingerprints during a distributed query execution.

NOTE: this implementation don't provide any knobs to lock part and hence its UUID. Any mutations/merge will
update part's UUID.

* add _part_uuid virtual column, allowing to use UUIDs in predicates.

63a8f463f9 Allow writing partial buffer 
In #6012 the behavior of the WriteBuffer has been changed.

Before, WriteBuffer write the data when next() is called.
After, WriteBuffer will write the data if, and only if, the buffer is
full.

See the discussion here [1].
