Expand description

Settings for the EthStateCache.

Byte budgets cover estimated payload sizes, excluding map and request queue overhead. Shared payloads can remain allocated after eviction while other components still hold references.

Fields§

§max_blocks: u32

Max number of blocks in cache.

Default is 1000.

§max_receipts: u32

Max number of blocks’ receipts in cache.

Default is 500.

§max_bals: u32

Max number of EVM BALs in cache.

Default is 1000.

§max_blocks_bytes: usize

Maximum estimated memory retained by the block cache, in bytes.

Defaults to 2 GiB. Zero disables caching. The entry count limit also applies.

§max_receipts_bytes: usize

Maximum estimated memory retained by the receipts cache, in bytes.

Defaults to 1 GiB. Zero disables caching. The entry count limit also applies.

§max_bals_bytes: usize

Maximum estimated memory retained by the BAL cache, in bytes.

Defaults to 500 MiB. Zero disables caching. The entry count limit also applies.

§idle_timeout: Duration

Duration after which an unused block, receipts collection, or BAL is evicted.

Defaults to one hour. Successful lookups refresh the timeout. Zero disables expiration. Periodic cleanup starts at least once per minute and removes expired entries in bounded batches.

§cache_computed_bals: bool

Cache BALs computed by RPC requests for transaction tracing. Disabled by default.

§prewarm_bals: Option<usize>

Prewarm BALs until native BAL support, optionally replaying this many recent blocks on startup. Some(0) prewarms only new canonical blocks; None disables prewarming.

Implies caching of BALs computed by RPC requests.

§max_concurrent_db_requests: usize

Max number of concurrent database requests.

Default is 512.

§max_cached_tx_hashes: u32

Maximum number of transaction hashes to cache for transaction lookups.
