Arguments specific to the ChainDB, not to the ImmutableDB, VolatileDB, or LedgerDB.

Fields

cdbsBlocksToAddSize ∷ Word
Size of the queue used to store asynchronously added blocks. This is the maximum number of blocks that could be kept in memory at the same time when the background thread processing the blocks can't keep up.
cdbsGcDelay ∷ DiffTime
Delay between copying a block to the ImmutableDB and triggering a garbage collection for the corresponding slot on the VolatileDB.
The goal of the delay is to ensure that the write to the ImmutableDB has been flushed to disk before deleting the block from the VolatileDB, so that a crash won't result in the loss of the block.
cdbsGcInterval ∷ DiffTime
Batch all scheduled GCs so that at most one GC happens every cdbsGcInterval.
cdbsRegistry ∷ HKD f (ResourceRegistry m)
cdbsTracer ∷ Tracer m (TraceEvent blk)
cdbsHasFSGsmDB ∷ HKD f (SomeHasFS m)
cdbsTopLevelConfig ∷ HKD f (TopLevelConfig blk)
cdbsLoE ∷ GetLoEFragment m blk
If this is LoEEnabled, it contains an action that returns the current LoE fragment.

newtype RelativeMountPoint Source #

A relative path for a MountPoint

The root is determined by context.

Arguments

∷ ∀ m blk. (ConsensusProtocol (BlockProtocol blk), IOLike m)
⇒ ResourceRegistry m
→ TopLevelConfig blk
→ ExtLedgerState blk	Initial ledger
→ ChunkInfo
→ (blk → Bool)	Check integrity
→ (RelativeMountPoint → SomeHasFS m)	Immutable FS, see `NodeDatabasePaths`
→ (RelativeMountPoint → SomeHasFS m)	Volatile FS, see `NodeDatabasePaths`
→ Incomplete ChainDbArgs m blk	A set of incomplete arguments, possibly modified wrt `defaultArgs`
→ Complete ChainDbArgs m blk

defaultArgs ∷ ∀ m blk. Monad m ⇒ Incomplete ChainDbArgs m blk Source #

Default arguments

See defaultArgs, defaultArgs, defaultArgs, and defaultSpecificArgs for a list of which fields are not given a default and must therefore be set explicitly.
