📖
Begriffe

Column Family

Logical grouping of related columns in columnar databases, enabling hierarchical data organization for more efficient access.

📖
Begriffe

Row Group

Processing unit in columnar formats containing a set of vertically stored rows, optimizing I/O operations and compression.

📖
Begriffe

Column Chunk

Physical data fragment containing values from a specific column, compressed and stored independently to enable selective data access.

📖
Begriffe

Parquet Format

Open-source columnar storage format optimized for analytical workloads, using efficient encoding and advanced compression techniques.

📖
Begriffe

ORC Format

Columnar format optimized for Apache Hive, providing high compression and fast query performance with strict data typing.

📖
Begriffe

Vectorized Execution

Processing technique where operations are applied to batches of data in parallel, reducing overhead and improving columnar query throughput.

📖
Begriffe

Predicate Pushdown

Optimization pushing query filters to the data source, reducing the amount of data read and processed in columnar systems.

📖
Begriffe

Column Pruning

Technique eliminating the reading of unrequired columns in a query, leveraging columnar organization to minimize disk access.

📖
Begriffe

Dictionary Encoding

Compression method replacing repeated values with short identifiers, particularly effective for categorical data in columnar systems.

📖
Begriffe

Zone Maps

Metadata indicating minimum and maximum values in data segments, allowing rapid elimination of irrelevant blocks during queries.

📖
Begriffe

Delta Encoding

Compression technique storing differences between successive values rather than absolute values, optimal for ordered and temporal data.

📖
Begriffe

RLE Encoding

Run Length Encoding compressing sequences of identical values by storing the value and the number of consecutive occurrences.

📖
Begriffe

Bloom Filters

Probabilistic data structures allowing quick determination of a value's absence in a set, optimizing searches in columnar systems.

📖
Begriffe

Skip Index

Metadata allowing direct skipping to relevant data blocks during sequential column reading, accelerating data scans.

📖
Begriffe

Vertical Partitioning

Process of physically dividing data into partitions based on columns, enabling efficient distribution and parallelism in columnar clusters.

📖
Begriffe

Pushdown Aggregation

Optimization moving aggregation calculations to the storage layer, reducing the volume of data transferred in columnar architectures.
