Datasets themselves are of varying size, from a few bytes to multiple gigabytes. Each version contains metadata (keys and values) and a data pointer. You can think of a data pointer as special metadata that points to where the actual data you published is stored. Direct data pointers are automatically replicated globally.

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).

Hadoop can execute MapReduce applications in various languages, including Java, Ruby, Python, and C++. NameNode is often given a large space to contain metadata for large-scale files. The metadata should come from a single file for optimal space use and economic benefit. And storing these metadata in RAM will become problematic.

This layer stores the metadata needed to optimize a query or filter data. To enable and keep table maintenance simpler, all DML functions (such as DELETE and UPDATE) make use of the underlying micro-partition metadata. For instance, only a small number of operations, such as deleting all of the records from a table, are metadata-only.

To run Kafka, remember that your local environment must have Java 8+ installed on it. 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. Kafka JMS (Java Messaging Service) The delivery system is based on a pull mechanism.

In full shutdown backup approach, a periodic complete shutdown of the HBase cluster is performed so that the Master and Region Servers go down and if there are hardly any chances of losing out the in-flight changes happening to metadata or StoreFiles. Which is the best way to read HBase data using a Spark Job or a Java program?
