海外TECH DEV Community Data Lake explained https://dev.to/barbara/data-lake-explained-3cel Data Lake explained WHAT the famous analogyA data warehouse is like a producer of water where you are handed bottled water in a particular size and shape of a bottle Whereas a data lake is a place where many streams of water flow into it and it s up to everyone to get the water the way he wants it WHYThe data lake is the new data warehouse It shares the goals of the data warehouse of supporting business insights beyond the day to day transaction data handling The main factors for the evolution of the data warehouse are the following ones Abundance of Unstructured DataAs we are collecting more and more data text xml json song voice sensor data That is why we need to find a better way to process it It is possible to transform data during the ETL process But if we are deciding on a particular form of transformation we might not have the flexibility we need afterwards for analysis This applies for deep json structures where we do not want to distill only some elements Another example would be text pdf documents that need to be stored as blobs but are useless unless processed to extract some metrics The Rise of Big Data TechnologiesThe HDFS Hadoop Distributed File System made it possible to store Petabytes of data on commodity hardware It has less cost per TB compared to a MPP Massive Parallel Programming database like Redshift Thanks to new processing tools like MapReduce or Spark we can process data at scale on the same hardware used for storage Schema On Read makes it possible to do data analytics without inserting into a predefined schema or process unstructured text New Roles and Advanced AnalyticsAs data is treated as the new oil people want to get out the most value of it A data scientist often needs to represent and join data sets together from external sources For this case the clean consistent and performant model a data warehouse architecture provides for business users does not work The data lake needs to cope with these agile and ad hoc nature data exploration activities Also machine learning or natural language processing needs to access the data in a different form than ie a star schema provides BENEFITS Lower costs more possibilitiesETL Offloading Same hardware for storage and processing a big data cluster There is no more need for a special ETL grid or additional storage for an staging area Dimensional modelling with conformed dimensions or data marts for high known value dataLow cost per TB makes it possible to store low unknown value data for analytics Schema on ReadWith the big data tools in the hadoop ecosystem like Spark it is as easy to work with a file as it is to work with a database but without creating and inserting into a database This is called schema on read as for the schema of a table it is either inferred or specified and the data is not inserted into it but upon read the data is checked against the specified schema Spark Example Schema InferencedfExample spark read csv data example csv inferSchema True header true sep The schema is inferenced but we want to make sure the type is set correctly For a example a date field should not be set as a string To better control types and malformed data we can specify a schema StructType to make sure everything is correct It is still schema on read though We also can specify what should happen to a row that is not conform to our schema The options are drop it replace with null or fail exampleSchema StructType StructField id IntegerType StructField amount IntegerType StructField info StringType StructField date DateType dfExample spark read csv data example csv schema exampleSchema sep mode DROPMALFORMED With that we can do direct querying on the fly without database insertions dfExample groupBy info sum amount orderBy desc sum amount show We can also write SQL with creating a temporary table Nothing will be written to a database here dfExample createOrReplaceTempView example spark sql SELECT info sum amount as total amount FROM example GROUP BY info ORDER BY total amount desc show Unstructured data supportSpark can read and write files intext based formatsbinary formats like Avro saves space and Parquet that is a columnar storage andcompressed formats like gzip and snappydfText spark read text text gz dfSample spark read csv sample csv Spark can read and write files from a variety of file systems local HDFS S and a variety of databases SQL MongoDB Cassandra Neoj Everything that is exposed in a single abstraction the dataframe can be processed with SQL ISSUESA data lake can easily transform into an chaotic data garbage dump Data governance is hard to implement as a data lake can be used for cross department data and external data Sometimes it is unclear for what cases a data lake should replace offload or work in parallel with a data warehouse or data marts In all cases dimensional modelling is a valuable practice The Data Lake SUMMARYAll types of data are welcome Data is stored as is transformations are done later Extract Load Transform ELT instead of ETL Data is processed with schema on read There is no predefined star schema before the transformationmassive parallelism and scalability come out of the box with all big data processing tools We can use columnar storage parquet without expensive MPP
