Synopsis

Documentation

data FlushFrequency Source #

The number of blocks in the immutable part of the chain that we have to see before we flush the ledger tables to disk. See onDiskShouldFlush.

Constructors

DefaultFlushFrequency

A default value, which is determined by a specific SnapshotPolicy. See defaultSnapshotPolicy as an example.

RequestedFlushFrequency Word64

A requested value: the number of diffs in the immutable part of the chain required before flushing.

DisableFlushing

To disable flushing, to be used in tests
