# MergeTree Engine Family
|
||
|
||
Table engines from the MergeTree family are the core of ClickHouse data storage capabilities. They provide most features for resilience and high-performance data retrieval: columnar storage, custom partitioning, sparse primary index, secondary data-skipping indexes, etc.
|
||
|
||
Base [MergeTree](../../../engines/table-engines/mergetree-family/mergetree.md) table engine can be considered the default table engine for single-node ClickHouse instances because it is versatile and practical for a wide range of use cases.
|
||
|
||
For production usage [ReplicatedMergeTree](../../../engines/table-engines/mergetree-family/replication.md) is the way to go, because it adds high-availability to all features of regular MergeTree engine. A bonus is automatic data deduplication on data ingestion, so the software can safely retry if there was some network issue during insert.
|
||
|
||
All other engines of MergeTree family add extra functionality for some specific use cases. Usually, it’s implemented as additional data manipulation in background.
|
||
|
||
The main downside of MergeTree engines is that they are rather heavy-weight. So the typical pattern is to have not so many of them. If you need many small tables, for example for temporary data, consider [Log engine family](../../../engines/table-engines/log-family/index.md).
