This version of the store is used for the rollup nodes for protocols for and after Nairobi, i.e. >= 17.

include module type of struct include Store_v1 end
include module type of struct include Store_v0 end

Storage mapping commitment hashes to the level when they were published by the rollup node. It only contains hashes of commitments published by this rollup node.

Dal_slot_pages is a Store_utils.Nested_map used to store the contents of dal slots fetched by the rollup node, as a list of pages. The values of this storage module have type `string list`. A value of the form page_contents refers to a page of a slot that has been confirmed, and whose contents are page_contents.

include Store_sig.S with type 'a store := 'a Store_v0.store
module Dal_pages = Store_v1.Dal_pages
module Dal_processed_slots = Store_v1.Dal_processed_slots
module Dal_slots_statuses = Store_v1.Dal_slots_statuses

Dal_slots_statuses is a Store_utils.Nested_map used to store the attestation status of DAL slots. The values of this storage module have type ``Confirmed | `Unconfirmed`, depending on whether the content of the slot has been attested on L1 or not. If an entry is not present for a (block_hash, slot_index), this means that the corresponding block is not processed yet.

include Store_sig.S with type 'a store := 'a Store_v1.store

Storage for persisting messages downloaded from the L1 node.

Storage for persisting inboxes.

Storage containing commitments and corresponding commitment hashes that the rollup node has knowledge of.

module Lcc : sig ... end

Storage containing the last cemented commitment.

Storage containing a single commitment for the last published commitment.

Published slot headers per block hash, stored as a list of bindings from Dal_slot_index.t to Dal.Slot.t. The encoding function converts this list into a Dal.Slot_index.t-indexed map.

Confirmed DAL slots histories cache. See documentation of Dal_slot_repr.Slots_history for more details.

module Protocols : sig ... end
module Gc_levels : sig ... end

Data related to the effects of garbage collection.

History mode of the rollup node.

include Store_sig.S with type 'a store := 'a store
type 'a t = [< `Read | `Write Read ] as 'a store

Type of store. The parameter indicates if the store can be written or only read.

Read/write store t.

Read only store t.

val version : Store_version.t

Version supported by this code.

close store closes the store.

val load : 'a Tezos_layer2_store.Store_sigs.mode -> index_buffer_size:int -> l2_blocks_cache_size:int -> string -> 'a store Tezos_base.TzPervasives.tzresult Lwt.t

load mode ~index_buffer_size ~l2_blocks_cache_size directory loads a store from the data persisted in directory. If mode is Store_sigs.Read_only, then the indexes and irmin store will be opened in readonly mode and only read operations will be permitted. This allows to open a store for read access that is already opened in Store_sigs.Read_write mode in another process. index_buffer_size is the maximum cache size in memory before it is flushed to disk. l2_blocks_cache_size is the number of L2 blocks the rollup node will keep in memory.

val readonly : _ t -> ro

readonly store returns a read-only version of store.

iter_l2_blocks ?progress metadata store f iterates f on all L2 blocks reachable from the head, from newest to oldest. If progress is provided, a progress bar is displayed with the progress messages during the iteration.

val gc : rw -> level:int32 -> unit Tezos_base.TzPervasives.tzresult Lwt.t

gc store ~level asynchronously garbage collects everything from the store that concerns blocks for levels below level.

val wait_gc_completion : 'a t -> unit Lwt.t

wait_gc_completion store returns a blocking thread if a GC run is currently ongoing.

val is_gc_finished : 'a t -> bool

is_gc_finished t returns true if there is no GC running.
