Method Detail

getIndexToKeep

long getIndexToKeep(org.neo4j.causalclustering.core.consensus.log.segmented.Segments segments)

Returns the index to keep depending on the configuration strategy. This does not factor in the value of the safe index to prune to. It is worth noting that the returned value may be the first available value, rather than the first possible value. This signifies that no pruning is needed.

Parameters:

segments - The segments to inspect.

Returns:

The lowest index the pruning configuration allows to keep. It is a value in the same range as append indexes, starting from -1 all the way to Long.MAX_VALUE.
