min_bytes_* MergeTree table settings

These settings are available in system.merge_tree_settings and are autogenerated from the ClickHouse snapshot.

min_bytes_for_full_part_storage

Minimal uncompressed size in bytes to use full type of storage for data part instead of packed

min_bytes_for_wide_part

Minimum number of bytes/rows in a data part that can be stored in Wide format. You can set one, both or none of these settings.

min_bytes_to_prewarm_caches

Minimal size (uncompressed bytes) to prewarm mark cache and primary index cache for new parts

min_bytes_to_rebalance_partition_over_jbod

Sets minimal amount of bytes to enable balancing when distributing new big parts over volume disks JBOD.

Possible values:

• Positive integer.
• 0 — Balancing is disabled.

Usage

The value of the min_bytes_to_rebalance_partition_over_jbod setting should not be less than the value of the max_bytes_to_merge_at_max_space_in_pool / 1024. Otherwise, ClickHouse throws an exception.
