Delete branch "improve-history-cache"
Deleting a branch is permanent. Although the deleted branch may continue to exist for a short time before it actually gets removed, it CANNOT be undone in most cases. Continue?
This updates the caching of address histories to match the pattern used in
scribe
, which is much more performant. In addition to caching the final address histories, the tx_hash and heights are also cached in a smaller (but more items) cache that allows for a high hit rate on blocks containing transactions that touch many addresses (where each touched address has a fairly large history).Additionally, the history cache is now updated in place using a minimal set of batched lookups upon a new block instead of being cleared.
