Module mito_engine_options 

Option keys for the mito engine. We define them in this mod so the create parser can use it to validate table options.

Structs

Option key for the per-table auto flush interval.

COMPACTION_OVERRIDE

Option key for forcing compaction options override.

COMPACTION_TYPE

Option key for compaction type.

COMPACTION_TYPE_TWCS

TWCS compaction strategy.

MAX_ROW_GROUP_ROW_COUNT

Option key for the max number of rows in a parquet row group.

MAX_ROW_GROUP_ROW_COUNT_LIMIT

Upper bound for MAX_ROW_GROUP_ROW_COUNT.

MEMTABLE_BULK_ENCODE_BYTES_THRESHOLD

Option key for bulk memtable encode bytes threshold.

MEMTABLE_BULK_ENCODE_ROW_THRESHOLD

Option key for bulk memtable encode row threshold.

Option key for merge mode.

PRESERVE_ROW_SEQUENCE

Option key for preserving per-row sequence numbers through flush and compaction.

SKIP_WAL_KEY

Option key for skipping WAL.

SNAPSHOT_READ

Option key for snapshot read.

SST_FORMAT_KEY

Option key for sst format.

TTL_KEY

Option key for TTL(time-to-live)

TWCS_ACTIVE_WINDOW_L1_MERGE_TRIGGER

Option key for the active-window L1 safety compaction threshold.

TWCS_ACTIVE_WINDOW_TRIGGER_FILE_NUM

Option key for twcs min file num to trigger compaction in the active window.

TWCS_FALLBACK_TO_LOCAL

Option key for twcs fallback to local.

TWCS_INACTIVE_WINDOW_L1_MERGE_TRIGGER

Option key for the inactive-window L1 compaction threshold.

TWCS_INACTIVE_WINDOW_TRIGGER_FILE_NUM

Option key for twcs min file num to trigger compaction in an inactive window.

TWCS_MAX_OUTPUT_FILE_SIZE

Option key for twcs max output file size.

WAL_OPTIONS_KEY

Option key for all WAL options. An encoded wal options will be wrapped into a (WAL_OPTIONS_KEY, encoded wal options) key-value pair and inserted into the options of a RegionCreateRequest.

WRITE_BUFFER_SIZE_KEY

Option key for the per-region write buffer size.

Functions

is_mito_engine_option_key
