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

rpc_store_bitmap_periodic_compaction_days: Option<u64>

Optional periodic-compaction interval override for the embedded RPC store’s transaction and event bitmap SSTs, in days. When omitted, the RPC store’s RocksDB configuration uses its 7-day default. Zero disables periodic compaction; positive values are the SST-age interval.

Expired merge-written buckets may need one interval to materialize and another to be filtered, so this is not a wall-clock deletion SLA.

rpc_store_num_checkpoint_snapshots_to_retain: usize

Number of per-checkpoint RocksDB snapshots the embedded RPC store retains in memory. The store’s synchronizer takes a snapshot each time every pipeline in its cohort has committed a checkpoint; once this many are retained, each new one evicts the oldest. Zero (the default) disables snapshotting.

Nothing reads these snapshots yet; they are intended to back consistent pagination for the RPC store’s live-index reads. Retaining them prevents compaction from dropping keys overwritten or deleted after the oldest retained snapshot, and from combining merge operands that a snapshot separates, so a key merged in many checkpoints (a balance, the current bitmap bucket) keeps up to one operand per checkpoint in the window for reads to fold. Larger values therefore cost disk space, compaction work, and read latency. At ~4 checkpoints per second, 15,000 snapshots span about an hour.

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
