Fields§

§block_cache_capacity_mb: Option<usize>

Configure the capacity of the block cache in MB explicitly. The overridden value will only be effective if:

  1. meta_cache_capacity_mb and shared_buffer_capacity_mb are also configured explicitly.
  2. block_cache_capacity_mb + meta_cache_capacity_mb + meta_cache_capacity_mb doesn’t exceed 0.3 * non-reserved memory.
§block_cache_shard_num: Option<usize>

Configure the number of shards in the block cache explicitly. If not set, the shard number will be determined automatically based on cache capacity.

§block_cache_eviction: CacheEvictionConfig§meta_cache_capacity_mb: Option<usize>

Configure the capacity of the block cache in MB explicitly. The overridden value will only be effective if:

  1. block_cache_capacity_mb and shared_buffer_capacity_mb are also configured explicitly.
  2. block_cache_capacity_mb + meta_cache_capacity_mb + meta_cache_capacity_mb doesn’t exceed 0.3 * non-reserved memory.
§meta_cache_shard_num: Option<usize>

Configure the number of shards in the meta cache explicitly. If not set, the shard number will be determined automatically based on cache capacity.
