## use_compact_format_in_distributed_parts_names {#use_compact_format_in_distributed_parts_names}
Uses compact format for storing blocks for async (`insert_distributed_sync`) INSERT into tables with `Distributed` engine.
Possible values:
- 0 — Uses `user[:password]@host:port#default_database` directory format.
- 1 — Uses `[shard{shard_index}[_replica{replica_index}]]` directory format.
Default value: `1`.
!!! note "Note"
- with `use_compact_format_in_distributed_parts_names=0` changes from cluster definition will not be applied for async INSERT.
- with `use_compact_format_in_distributed_parts_names=1` changing the order of the nodes in the cluster definition, will change the `shard_index`/`replica_index` so be aware.
## background_buffer_flush_schedule_pool_size {#background_buffer_flush_schedule_pool_size}
Sets the number of threads performing background flush in [Buffer](../../engines/table-engines/special/buffer.md)-engine tables. This setting is applied at the ClickHouse server start and can’t be changed in a user session.

# sumWithOverflow {#sumwithoverflowx}
Computes the sum of the numbers, using the same data type for the result as for the input parameters. If the sum exceeds the maximum value for this data type, the function returns an error.
Computes the sum of the numbers, using the same data type for the result as for the input parameters. If the sum exceeds the maximum value for this data type, it is calculated with overflow.

Таблицы типа Buffer используются в тех случаях, когда от большого количества серверов поступает слишком много INSERT-ов в единицу времени, и нет возможности заранее самостоятельно буферизовать данные перед вставкой, в результате чего, INSERT-ы не успевают выполняться.
Заметим, что даже для таблиц типа Buffer не имеет смысла вставлять данные по одной строке, так как таким образом будет достигнута скорость всего лишь в несколько тысяч строк в секунду, тогда как при вставке более крупными блоками, достижимо более миллиона строк в секунду (смотрите раздел «Производительность»).
