## Core database replacement wrapper object
|
|
## ========================================
|
|
##
|
|
## See `core_db/README.md` for implementation details
|
|
##
|
|
## This module provides a memory datanase only. For providing a persistent
|
|
## constructor, import `db/code_db/persistent` though avoiding to
|
|
## unnecessarily link to the persistent backend library (e.g. `rocksdb`)
|
|
## when a memory only database is used.
|

# Default database backend selection. Note that an `Aristo` type backend
|
|
# should run on a `LedgerCache` type ledger (will not work with
|
|
# `LegacyAccountsCache`.) The `common` module automatically sets that up
|
|
# (unless overridden.) Practically, these constants are mainly used for
|
|
# setting up DB agnostic unit/integration tests.
