- Simpler start boilerplate, simpler structures to deal with!
This version introduces a different much simplified concept of Lake Framework usage. Thus it brings breaking changes.
We introduce near-lake-primitives
crate with simplified primitive structures (e.g Block
, Transaction
, StateChange
, etc.) which is heavily used by Lake Framework since now.
And some other changes:
-
LakeConfig
is renamed to be justLake
. It is done because since this updateLake
is accepting the indexing function from a user and runs the streamer implicitly. Thus shortening and simplifying the start boilerplate to something like this:fn main() -> anyhow::Result<()> { // Lake Framework start boilerplate near_lake_framework::LakeBuilder::default() .mainnet() .start_block_height(80504433) .build()? .run(handle_block) // user-defined asynchronous function that handles each block }
Please note your main function isn't required to be asynchronous anymore! It is now handled by Lake Framework under the hood.
- Upgrade near primitives crate to
0.17.0
- Upgrade
tokio
version to the latest (1.28.2
)
- Refactor
s3_fetchers
to allow testing - Fix
betanet
default region (the corresponding bucket is in different region)
- Add support for Meta Transactions NEP-366 by upgrading
near-indexer-primitives
to0.16
- Add helper function for connecting to
betanet
lake
Delegate
action has been introduced innear-primitives::views::ActionView
, this should be handled everywhere you are handlingActionView
- Fix of possible silent stops of the streamer (firing logs and returning errors where necessary)
- Fix the issue the streamer was always 1 block behind
- Renamed a few internal methods to reflect what they do
- Added debug and error logs in a few places
- Introduced a
LakeError
enum usingthiserror
(#42), but not exposing it yet to avoid breaking changes to the framework (for now, it will be done in0.7.0
) - Added proper error handling in a few places
- Updated the dependencies version of AWS crates
- Upgrade underlying dependency
near-indexer-primitives
to versions between 0.15 and 0.16
near-indexer-primitives
reflects some breaking changes in the data types. Some of the fields that were previously
a base64-encoded String that now became raw Vec<u8>
:
views::ActionView::FunctionCall.args
views::QueryResponseKind::ViewState
views::ExecutionStatusView::SuccessValue
Refer to this nearcore
commit to find all the changes of this kind.
- Fixed the bug that caused a lag by 100 blocks that was introduced in 0.5.1
- Avoid spiky latency with streaming block heights preload
0.5.0 - 2022-06-16
- Cleaned up unused depdendencies
- Added the configuration option to control the size of the pool of
preloaded blocks
blocks_preload_pool_size
(100 remains to be the default) - Update AWS dependencies to
0.13.0
- Dropped the previously allowed way to instantiate LakeConfig by manually initializing the public fields in favor of the builder pattern
0.4.1 - 2022-06-14
- Bumped the minimum required version of
serde_json
to 1.0.75 to avoid confusing errors whenarbitrary_precision
feature is enabled. - Extended the list of supported near-primitives versions from 0.12.0 to >=0.12.0,<0.15.0 to help downstream project avoid duplicate versions of near-primitives and its dependencies.
- Reduced verbosity level of recoverable errors from
ERROR
toWARN
0.4.0 - 2022-05-17
- Remove calls to
.unwrap()
and.expect()
within the stream sender that could panic. Instead, aResult
is returned from the sender task. - Remove calls to
.unwrap()
and.expect()
withins3_fetchers
module
- The
streamer()
function now returns a tuple, with the first element being aJoinHandle<Result<(), Error>>
that you can use to gracefully capture any errors that occurred within the sender task. If you don't care about errors, you can easily adapt to this change by changing:to this instead:let receiver = near_lake_framework::streamer(settings);
let (_, receiver) = near_lake_framework::streamer(settings);
0.3.0 - 2022-05-10
- Introduce
LakeConfigBuilder
for creating configslet config = LakeConfigBuilder.default() .testnet() .start_block_height(88220926) .build() .expect("Failed to build LakeConfig");
- Now you can provide custom AWS SDK S3
Config
use aws_sdk_s3::Endpoint; use http::Uri; use near_lake_framework::LakeConfigBuilder; let aws_config = aws_config::from_env().load().await; let mut s3_conf = aws_sdk_s3::config::Builder::from(&aws_config); s3_conf = s3_conf .endpoint_resolver( Endpoint::immutable("http://0.0.0.0:9000".parse::<Uri>().unwrap())) .build(); let config = LakeConfigBuilder::default() .s3_config(s3_conf) .s3_bucket_name("near-lake-data-custom") .start_block_height(1) .build() .expect("Failed to build LakeConfig");
LakeConfig
has a breaking change as we've removed s3_endpoint
and added s3_config
. Please, consider migrating to use LakeConfigBuilder
instead of directly crafting the Lakeconfig
0.2.0 - 2022-04-25
