Roy Crihfield	ae9834e60f	feat: ADR-040: Implement BadgerDB backend (#9848) ... ## Description Partially resolves: https://github.com/vulcanize/cosmos-sdk/issues/14 Implements a [BadgerDB](https://pkg.go.dev/github.com/dgraph-io/badger/v3)-based backend for the DB interface introduced by https://github.com/cosmos/cosmos-sdk/pull/9573 and specified by [ADR-040](eb7d939f86/docs/architecture/adr-040-storage-and-smt-state-commitments.md). This uses Badger's "managed" mode for version management, and supports optimistically concurrent transactions (required one [patch](https://github.com/dgraph-io/badger/pull/1716) upstream to fix handling of write conflicts). --- ### Author Checklist *All items are required.

Roy Crihfield	2c31451a55	feat: ADR 040: Implement in-memory DB backend (#9952) ... ## Description Implements an in-memory backend for the DB interface introduced by https://github.com/cosmos/cosmos-sdk/pull/9573 and specified by [ADR-040](eb7d939f86/docs/architecture/adr-040-storage-and-smt-state-commitments.md). This expands on the [btree](https://pkg.go.dev/github.com/google/btree)-based [`MemDB`](https://github.com/tendermint/tm-db/tree/master/memdb) from `tm-db` by using copy-on-write clones to implement versioning. Resolves: https://github.com/vulcanize/cosmos-sdk/issues/2 Will move out of draft once https://github.com/cosmos/cosmos-sdk/pull/9573 is merged and rebased on. ### Author Checklist *All items are required.

For other templates, add one of the following parameters to the url: - template=docs.md - template=other.md --> ## New DB interface to replace `tm-db` This introduces a new interface to wrap the backend KV store DB while supporting versioning and ACID transactions. Part of [ADR-040](eb7d939f86/docs/architecture/adr-040-storage-and-smt-state-commitments.md) changes. This has been revised to consist of only the interface types. All implementations and utilities will be in follow-up PRs. Partially resolves: https://github.com/vulcanize/cosmos-sdk/issues/2 --- ### Author Checklist *All items are required.
