Specific options for the metric engine to create or open a region.

Structs

Enums

Constants

DEFAULT_DATA_REGION_COMPACTION_TIME_WINDOW 🔒

The default compaction time window for metric engine data regions.

LEGACY_PARTITION_TREE_OPTION_PREFIX 🔒

Prefix for legacy memtable.partition_tree.* option keys. These keys are silently dropped by the metric engine; the partition tree memtable is gone.

SEG_ROW_COUNT_FOR_DATA_REGION 🔒

The empirical value for the seg row count of the metric data region. Compared to the mito engine, the pattern of the metric engine constructs smaller indices. Therefore, compared to the default seg row count of 1024, by adjusting it to a smaller value and appropriately increasing the size of the index, it results in an improved indexing effect.

Functions
