# jemalloc_bins
Contains information about memory allocations done via jemalloc allocator in different size classes (bins) aggregated from all arenas.
These statistics might not be absolutely accurate because of thread local caching in jemalloc.
Columns:
- `index` (UInt64) — Index of the bin ordered by size
- `large` (Bool) — True for large allocations and False for small
- `size` (UInt64) — Size of allocations in this bin
- `allocations` (UInt64) — Number of allocations
- `deallocations` (UInt64) — Number of deallocations
**Example**
Find the sizes of allocations that contributed the most to the current overall memory usage.
``` sql
SELECT
*,
allocations - deallocations AS active_allocations,
size * active_allocations AS allocated_bytes
FROM system.jemalloc_bins
WHERE allocated_bytes > 0
ORDER BY allocated_bytes DESC
LIMIT 10

# Manipulating SAMPLE BY expression
The following operations are available:
## MODIFY

ALTER TABLE [db].name [ON CLUSTER cluster] MODIFY SAMPLE BY new_expression
```
The command changes the [sampling key](../../../engines/table-engines/mergetree-family/mergetree.md) of the table to `new_expression` (an expression or a tuple of expressions).
The command changes the [sampling key](../../../engines/table-engines/mergetree-family/mergetree.md) of the table to `new_expression` (an expression or a tuple of expressions). The primary key must contain the new sample key.
The command is lightweight in the sense that it only changes metadata. The primary key must contain the new sample key.
## REMOVE
``` sql
ALTER TABLE [db].name [ON CLUSTER cluster] REMOVE SAMPLE BY
```
The command removes the [sampling key](../../../engines/table-engines/mergetree-family/mergetree.md) of the table.
The commands `MODIFY` and `REMOVE` are lightweight in the sense that they only change metadata or remove files.
:::note
It only works for tables in the [MergeTree](../../../engines/table-engines/mergetree-family/mergetree.md) family (including [replicated](../../../engines/table-engines/mergetree-family/replication.md) tables).
