海外TECH	DEV Community	The best Open-source lakehouse project, LakeSoul 2.0, supports snapshot, rollback, Flink, and Hive interconnection	https://dev.to/qazmkop/the-best-open-source-lakehouse-project-lakesoul-20-supports-snapshot-rollback-flink-and-hive-interconnection-49ni	The best Open source lakehouse project LakeSoul supports snapshot rollback Flink and Hive interconnectionI published an article about LakeSoul the data lakehouse a few months ago Recently LakeSoul has been updated and iterated with more perfect functions which can adapt to various scenarios and coordinate with business landings The DMetaSoul team released LakeSoul in early July which has been upgraded and optimized in many ways to improve the flexibility of its architectural design and better adapt to customers needs for future rapid business development Main objectives of LakeSoul development upgrade Support multiple computing engines Flink Presto etc refactoring Catalog and decouple Spark Use Postgres SQL protocol to support more demanding transactional mechanism and replace Cassandra SQL reducing the cost of Cassandra cluster management for enterprises Supports more functions in service production such as version snapshot rollback and Hive interconnection Strengthen ecosystem construction and improve upstream and downstream link design DMetaSoul achieved the design goal through Catalog reconstruction Spark and Catalog docking transformation development of new user features and support for the Flink computing engine Following are the features of LakeSoul Catalog refactoring Supports Postgres SQL protocolIn LakeSoul metadata and database interaction are fully implemented using the Postgres SQL PG protocol for reasons mentioned at On the one hand Cassandra does not support single table multi partition transactions On the other hand Cassandra cluster management has higher maintenance costs while the Postgres SQL protocol is widely used in enterprises and has lower maintenance costs You need to configure PG parameters For details click Independent Catalog frameworkIn LakeSoul the Catalog is decoupled from Spark to realize an independent metadata storage structure and interface Spark Flink Presto and other computing engines can interconnect with LakeSoul to provide multi engine streaming and batch integration capability The mechanism for detecting data submission conflictsMultiple tasks simultaneously writing data to the same table may cause data consistency problems in the same partition To solve this problem LakeSoul categorizes data commit types by defining four types Append Compaction Update and Merge so that when committing two commit types together the collision detection determines whether the commit succeeds or fails X and what happens when the commit succeeds For example if users must commit append data simultaneously to perform two tasks repeat the submission of the conflicting task when a conflict is detected Connect Spark to Catalog and transform itAfter refactoring decouple from Spark Since most of the original Spark functions are affected by decoupling it is necessary to transform the three parts based on the Catalog design framework Spark DDLDDL such as CREATE and drop table and DataSet related functions such as save in Spark SQL interact closely with the Catalog The information about the created table is stored in the Catalog LakeSoul retuned the Spark Scala interface to align it with Catalog Spark DataSinkThe DataSink insert into upsert etc involves not only metadata information such as tables but also data file record and partition data conflict detection when the stream batch task writes data DMetaSoul also adjusted the data operation interface after the Spark Job was completed Partitioning data commit conflict detection is also moved down to the Catalog Spark DataSourceMerge On Read MOR iS optimized On the DataSource In version data reads are sorted according to the write version number of data files When merging the latest version overwrites data of the old version by default In LakeSoul the Write Version attribute for data files was removed instead of using an ordered list of files with the latest build file at the end of the list In LakeSoul users using other MergeOperators provided by LakeSoul such as MergeOpLong needed to register and specify the associated column names when reading LakeSoulTable registerMergeOperator spark org apache spark sql lakesoul MergeOpLong longMOp LakeSoulTable forPath tablepath toDF withColumn value expr longMOp value select hash value If the table needs to use a large number of column fields or even all the fields it is inconvenient to specify one by one and if the user does not specify LakeSoul uses DefaultMergeOp for all the fields by default For example the user expected MergeNonNullOp to be used for all fields by default which was not met in version In LakeSoul LakeSoul implemented modifications to the default MergeOprator operation spark shell conf defaultMergeOpInfo org apache spark sql execution datasources v merge parquet batch merge operator DefaultMergeOp New service featuresIn LakeSoul three new features address the business requirements in the real world the snapshotSnapshots provide users with the ability to view historical data In LakeSoul when the user performs upsert Update insert and other operations the corresponding partition will generate a data version As the data continues to be updated the historical version will increase and the user hopes to check the historical data to facilitate data comparison etc LakeSoul allows users to view a version number by partition snapshot LakeSoulTable forPath tablepath range rangeval toDF show the rollbackRollback allows the user to take a historical version of the data as the current data enabling the data to go back in time LakeSoul also provides the ability to roll back data to a historical version by partition LakeSoulTable forPath tablepath rollbackPartition range rangeval Support HiveMany enterprises choose Hive as an offline data warehouse in the financial and Internet sectors In version LakeSoul considers the uniformity of the upstream computing engine and the diversity of the downstream data output Hive is the data warehouse tool that supports LakeSoul downstream first It would help if users created a hive appearance by putting a new Compaction file in the Spark conf directory When this Compaction happens it compacts this operation with a new Compaction file that does not support Merge On Read Only Copy On Write is supported LakeSoulTable forPath tablepath compaction range rangeval hiveExternalTableName Support FlinkLakeSoul supports Flink unified streaming and batch writing and implements Exactly once semantics It can ensure data accuracy for Flink CDC and other scenarios and combine Merge On Read and Schema AutoMerge capabilities provided by LakeSoul which has high commercial value for practical business scenarios such as multi table mergers and sub database mergers Conclusion LakeSoul version surrounding ecological system upgrade the further iterations pay attention to the upstream and downstream tools seamless ecological docking It also focuses on relevant features in enterprise business

海外TECH	DEV Community	Reusable State Patterns (Angular)	https://dev.to/this-is-angular/reusable-state-patterns-angular-59l9	Reusable State Patterns Angular This series explores how we can keep our code declarative as we adapt our features to progressively higher levels of complexity To avoid confusion read the introduction to the series first Level Reusable State PatternsLook what happens when we take out the object that manages our state export class ColorsComponent adapter createAdapter lt string gt Added createAdapter changeColor colors newColor index string number gt colors map color i gt i index newColor color selectors colors state gt state map color gt value color name color charAt toUpperCase color slice store createStore colors aqua aqua aqua this adapter Do you see how this simple change enables us to handle a lot more complexity We could easily create several stores for several independent lists of colors favoriteStore createStore colors favorite aqua aqua aqua this adapter dislikedStore createStore colors disliked orange orange orange this adapter neutralStore createStore colors neutral purple purple purple this adapter StackBlitzThat s pretty hideous but that s on the designer not us I called the state manager object adapter because NgRx calls its entity state manager entityAdapter NgRx Entity is thought of as an advanced pattern of NgRx but in our case creating our colors adapter was the most minimal and simple way to describe the state of colors We just defined it inline first Minimal code is flexible Every web app could eventually grow in complexity to the point where it has multiple instances of the same type of state on the same page I have encountered it a few times It sucked every time We are just dealing with colors but once on a large project a designer had me add a nd filtered paginated data grid on the same page and suddenly our state management solutionーwhich had coupled specific user events specific instances of state and business logic for state changes and derived state all togetherーbecame a big refactoring project Action payloads had to change and the state object had to become more deeply nested It took time and made the code uglier and harder to understand Using something other than state adapters for state logic is a syntactic dead end It might not come up as often as other problems but it does come up and it is usually unpredictable So no matter what state management library we end up using we should keep our state logic bundled together not too tightly coupled to events or side effect logic I personally think the adapter syntax is best createAdapter is something I ve implemented that provides type inference It s pretty simple to implement but all you really need is an object that holds state change functions and selectors You don t need any library for that Next we ll talk about asynchronous sources of state	2022-07-08 08:02:55
