Expand description

StateArchivalSettings is an XDR Struct defines as:

struct StateArchivalSettings {
    uint32 maxEntryTTL;
    uint32 minTemporaryTTL;
    uint32 minPersistentTTL;

    // rent_fee = wfee_rate_average / rent_rate_denominator_for_type
    int64 persistentRentRateDenominator;
    int64 tempRentRateDenominator;

    // max number of entries that emit archival meta in a single ledger
    uint32 maxEntriesToArchive;

    // Number of snapshots to use when calculating average BucketList size
    uint32 bucketListSizeWindowSampleSize;

    // How often to sample the BucketList size for the average, in ledgers
    uint32 bucketListWindowSamplePeriod;

    // Maximum number of bytes that we scan for eviction per ledger
    uint32 evictionScanSize;

    // Lowest BucketList level to be scanned to evict entries
