Configuration for MitoEngine.
Before using the config, make sure to call MitoConfig::validate()
to check if the config is valid.
Fields§
§num_workers: usize
Number of region workers (default: 1/2 of cpu cores). Sets to 0 to use the default value.
worker_channel_size: usize
Request channel size of each worker (default 128).
worker_request_batch_size: usize
Max batch size for a worker to handle requests (default 64).
manifest_checkpoint_distance: u64
Number of meta action updated to trigger a new checkpoint for the manifest (default 10).
compress_manifest: bool
Whether to compress manifest and checkpoint file by gzip (default false).
max_background_flushes: usize
Max number of running background flush jobs (default: 1/2 of cpu cores).
max_background_compactions: usize
Max number of running background compaction jobs (default: 1/4 of cpu cores).
max_background_purges: usize
Max number of running background purge jobs (default: number of cpu cores).
auto_flush_interval: Duration
Interval to auto flush a region if it has not flushed yet (default 30 min).
global_write_buffer_size: ReadableSize
Global write buffer size threshold to trigger flush.
global_write_buffer_reject_size: ReadableSize
Global write buffer size threshold to reject write requests.
sst_meta_cache_size: ReadableSize
Cache size for SST metadata. Setting it to 0 to disable the cache.
vector_cache_size: ReadableSize
Cache size for vectors and arrow arrays. Setting it to 0 to disable the cache.
page_cache_size: ReadableSize
Cache size for pages of SST row groups. Setting it to 0 to disable the cache.
selector_result_cache_size: ReadableSize
Cache size for time series selector (e.g. last_value()
). Setting it to 0 to disable the cache.
enable_write_cache: bool
Whether to enable the write cache.
write_cache_path: String
File system path for write cache dir’s root, defaults to {data_home}
.
write_cache_size: ReadableSize
Capacity for write cache.
write_cache_ttl: Option<Duration>
TTL for write cache.
sst_write_buffer_size: ReadableSize
Buffer size for SST writing.
parallel_scan_channel_size: usize
Capacity of the channel to send data from parallel scan tasks to the main task (default 32).
allow_stale_entries: bool
Whether to allow stale entries read during replay.
index: IndexConfig
Index configs.
inverted_index: InvertedIndexConfig
Inverted index configs.
fulltext_index: FulltextIndexConfig
Full-text index configs.
bloom_filter_index: BloomFilterConfig
Bloom filter index configs.
memtable: MemtableConfig
Memtable config
min_compaction_interval: Duration
Minimum time interval between two compactions. To align with the old behavior, the default value is 0 (no restrictions).
