Restriction on deleting tables.
If the size of a [MergeTree](../../engines/table-engines/mergetree-family/mergetree.md) table exceeds `max_table_size_to_drop` (in bytes), you can’t delete it using a DROP query.
If the size of a [MergeTree](../../engines/table-engines/mergetree-family/mergetree.md) table exceeds `max_table_size_to_drop` (in bytes), you can’t delete it using a [DROP](sql-reference/statements/drop.md) query or [TRUNCATE](../../sql-reference/statements/truncate.md) query.
If you still need to delete the table without restarting the ClickHouse server, create the `<clickhouse-path>/flags/force_drop_table` file and run the DROP query.
This setting does not require a restart of the Clickhouse server to apply. Another way to disable the restriction is to create the `<clickhouse-path>/flags/force_drop_table` file.
Default value: 50 GB.

Restriction on dropping partitions.
If the size of a [MergeTree](../../engines/table-engines/mergetree-family/mergetree.md) table exceeds `max_partition_size_to_drop` (in bytes), you can’t drop a partition using a [DROP PARTITION](../../sql-reference/statements/alter/partition.md#drop-partitionpart) query.

:::note
This limitation does not restrict drop table and truncate table, see [max_table_size_to_drop](#max_table_size_to_drop)

**Example**
``` xml

## max_thread_pool_size {#max-thread-pool-size}
ClickHouse uses threads from the Global Thread pool to process queries. If there is no idle thread to process a query, then a new thread is created in the pool. `max_thread_pool_size` limits the maximum number of threads in the pool.
