DataHub 0.8.36 – Metadata management is a big and complicated topic. DataHub is a completely independent product by LinkedIn, and the folks there definitely know what metadata is and how important it is. If you haven’t found your perfect metadata management system just yet, maybe it’s time to try DataHub!

This provided a nice overview of the breadth of topics that are relevant to data engineering including data warehouses/lakes, pipelines, metadata, security, compliance, quality, and working with other teams. For example, grouping the ones about metadata, discoverability, and column naming might have made a lot of sense.

Result The scatter plot below shows the AUC (y axis) of the classifier at varying compression levels (x axis = size of the feature store in bytes in logarithmic scale). Feature "freshness", as in how quickly recent events can be reflected to the feature store is very important, as recent events tend to have high informational value.

Easily Available- Snowflake Architecture is designed to be fully distributed, covering multiple zones and regions, and is highly fault-tolerant in the event of hardware failure. This layer stores the metadata needed to optimize a query or filter data. BigQuery charges users depending on how many bytes are read or scanned.

RocksDB-Cloud replicates all the data and metadata for a RocksDB instance to S3. The write ahead log is used to recover data in the memtables in the event of process restart. We limit the number of bytes that can be written per second to all RocksDB instances assigned to a leaf node. RocksDB cannot recover from machine failures.

Avro files store metadata with data and also let you specify independent schema for reading the files. If the primary NameNode goes down, the standby will take its place using the most recent metadata that it has. There is a pool of metadata which is shared by all the NameNodes. RowKey is internally regarded as a byte array.

In the event of a failure in the leader, the data is not lost because of the presence of replicas in other servers. Message Broker: Kafka is capable of appropriate metadata handling, i.e., a large volume of similar types of messages or data, due to its high throughput value.

StructType is a collection of StructField objects that determines column name, column data type, field nullability, and metadata. To define the columns, PySpark offers the pyspark.sql.types import StructField class, which has the column name (String), column type (DataType), nullable column (Boolean), and metadata (MetaData).
