In this blog post, we will discuss the AvroTensorDataset API, techniques we used to improve data processing speeds by up to 162x over existing solutions (thereby decreasing overall training time by up to 66%), and performance results from benchmarks and production. an array within a map, within a union, etc…). Default is 128 * 1024 (128KB).

When a client (producer/consumer) starts, it will request metadata about which broker is the leader for a partition—and it can do this from any broker. The key thing is that when you run a client, the broker you pass to it is just where it’s going to go and get the metadata about brokers in the cluster from. The default is 0.0.0.0,

To prevent the management of these keys (which can run in the millions) from becoming a performance bottleneck, the encryption key itself is stored in the file metadata. Each file will have an EDEK which is stored in the file’s metadata. hdfs dfs -cat” on the file triggers a hadoop KMS API call to validate the “DECRYPT” access.

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).
