Fields

num_latest_epoch_dbs_to_retain: usize

number of the latest epoch dbs to retain

epoch_db_pruning_period_secs: u64

time interval used by the pruner to determine whether there are any epoch DBs to remove

num_epochs_to_retain: u64

number of epochs to keep the latest version of objects for. Note that a zero value corresponds to an aggressive pruner. This mode is experimental and needs to be used with caution. Use u64::MAX to disable the pruner for the objects.

pruning_run_delay_seconds: Option<u64>

pruner’s runtime interval used for aggressive mode

max_checkpoints_in_batch: usize

maximum number of checkpoints in the pruning batch. Can be adjusted to increase performance

max_transactions_in_batch: usize

maximum number of transaction in the pruning batch

periodic_compaction_threshold_days: Option<usize>

enables periodic background compaction for old SST files whose last modified time is older than periodic_compaction_threshold_days days. That ensures that all sst files eventually go through the compaction process

num_epochs_to_retain_for_checkpoints: Option<u64>

number of epochs to keep the latest version of transactions and effects for

killswitch_tombstone_pruning: bool

disables object tombstone pruning. We don’t serialize it if it is the default value, false.

smooth: bool

enable_compaction_filter: bool

Enables the compaction filter for pruning the objects table. If disabled, a range deletion approach is used instead. While it is generally safe to switch between the two modes, switching from the compaction filter approach back to range deletion may result in some old versions that will never be pruned.

num_epochs_to_retain_for_indexes: Option<u64>
