## Backend DB traversal for Kvt DB
## ===============================
##
## This module provides iterators for the memory based backend or the
## backend-less database. Do import `kvt_walk/persistent` for the
## persistent backend though avoiding to unnecessarily link to the persistent
## backend library (e.g. `rocksdb`) when a memory only database is used.

Core db use differential tx layers for aristo and kvt (#1949) * Fix kvt headers * Provide differential layers for KVT transaction stack why: Significant performance improvement * Provide abstraction layer for database top cache layer why: This will eventually implemented as a differential database layers or transaction layers. The latter is needed to improve performance. behavioural changes: Zero vertex and keys (i.e. delete requests) are not optimised out until the last layer is written to the database. * Provide differential layers for Aristo transaction stack why: Significant performance improvement 2023-12-19 12:39:23 +00:00			`# Nimbus-eth1`

Simple stupid key-value table companion for Aristo DB (#1746) why: Additional tables needed for the `CoreDB` object with separate key-value table and MPT. details: + Stripped down copy of Aristo DB to have a similar look'n feel. Otherwise it is just a posh way for accessing `Table` objects or `RocksDB` data. + No unit tests yet, will be tested on the go. 2023-09-12 18:44:45 +00:00			`# Licensed under either of`
