v0.10.0

Atree v0.10.0 was refactored to reduce tech debt and it uses the updated features/stream-mode branch of fxamacker/cbor v2.8.

Notable issues resolved:

• #464 Refactor and reduce technical debt. This helps us add new features, maintain, and optimize (e.g., Lazy Decoding).
• #539 and flow-go#7221 Update to newer feature/stream-mode branch in fxamacker/cbor from 2.4 to 2.8. This resolves build issue for external projects that depend on fxamacker/cbor 2.5 or newer versions.

Other changes needed by this release are at fxamacker/cbor:

• PR fxamacker/cbor#640 update branch v2.4->v2.7 (+15,260 −4,371)
• PR fxamacker/cbor#650 update branch v2.7->v2.8 (+2,328 −952)

What's Changed

Upgrade to fxamacker/cbor v2.8

• Bump fxamacker/cbor to latest feature/stream-mode by @fxamacker in #542

We ran extensive tests to check backward compatibility, etc. #539 (comment) before merging the version bump to main branches.

Full Changelog: v0.9.0...v0.10.0

v0.9.0

@turbolent in #491 ported these 5 PRs from onflow/atree-internal:

• [feature] Provide WrapperValue and WrapperStorable interfaces (+5,937 −174) by @fxamacker
• [not a mainnet bug] Create unique composite type ID with no fields (+4 −0) by @fxamacker
  • This item only updates unreachable scenario (doesn't change behavior on mainnet).
• [not a mainnet bug] Update smoke test program for WrapperValue, etc. (+559 −35)by @fxamacker
• [not a mainnet bug] Fix slab iterator used only by tests (+148 −4) by @fxamacker
• [not a mainnet bug] Update LoadedValueIterator to check WrapperStorable (+1,712 −1,462)
  by @fxamacker

New Features

This release adds 2 new interfaces that can be used by client software:

• atree.WrapperValue
• atree.WrapperStorable

Some client software might use containers wrapped by an opaque object, which prevents external packages (e.g. Atree) from accessing the wrapped container.

To allow Atree to access such wrapped containers, client software can implement these new Atree interfaces in their opaque object to unwrap the container if needed.

Other changes are nits that don't affect mainnet (fix or improve some tests, cleanup an unreachable scenario, add more tests, etc.)

v0.8.1

What's Changed

This release adds the PersistentSlabStorage.HasUnsavedChanges() function.

HasUnsaveChanges() will be used by Cadence and Flow to optimize storage of domain registers to reduce payload count and mtrie count by 28.8% each (using zero downtime migration). Most of that effort will be at onflow/cadence and onflow/flow-go repos.

• Add function to check if address has unsaved changes in storage by @fxamacker in #450

Full Changelog: v0.8.0...v0.8.1

v0.8.0

Atree v0.8.0 introduces payload inlining and metadata deduplication to improve memory use, storage size, and speed of various servers that use payloads (not limited to EN). This improves network stability and performance as we handle future data growth.

Inlining and deduplication reduces payload count and mtrie nodes. This reduces size and growth rate of execution state.

• Inlining stores small arrays and maps (previously stored in their own payload) into an existing payload.
• Deduplication removes redundant metadata (e.g. Cadence struct field names and type information) to reduce payload size.

This release passed multiple types of tests, including 1034 hours of smoke tests that concluded on August 19, 2024.

Results exceeded goals mentioned in Scaling Execution Node (forum announcement).

Note

Sept. 4, 2024: 🏆 Atree inlined 500 million payloads (-61%) and eliminated over 1 billion mtrie nodes on mainnet!

Impact of these payload and mtrie node reductions include:

• Reduced RAM use by hundreds of GB on each mainnet execution node.
• Reduced SSD storage use (e.g. checkpoint file sizes).
• Reduced network bandwidth for chunk data packs (mentioned by Peter).
• Speedup transactions by 5-8% (mentioned by Jan).
• Speedup network upgrades (e.g. Cadence 1.0 migrations, future migrations).
• Future efficiency of other servers, components, databases (files/cache/index), etc. that benefit from fewer payloads.

Sept. 30, 2024: 🏆 Beyond execution nodes, bluesign shared a 5x speedup in tinyAN bootstrap time!
"btw amazing work this atree inlining, my tinyAN bootstrap time improved like 5x"

Future: We can replace nonatree domain payloads with atree payloads to reduce mainnet payload count by another 20-30%.

While devnet (shown below) had better percentage improvements, mainnet eliminated more mtrie nodes (over 1 billion)!
