We are excited to announce the Ampool 2.0 release which is an important milestone for Ampool. This release includes many new features and important performance improvements.
Following major features are added:
FTable Storage Format
The FTable employs block strategy for its in-memory layer that groups multiple records together and minimizes per record storage overhead and the overall memory footprint. Thus, for append-only fact tables, logs or metrics, it helps you to make optimal usage of available memory. With 2.0 following three different formats are supported.
- AMP_BYTES : The rows are serialized using Ampool specific encoding and are stored individually. This may consume more memory but there is no additional overhead during scan to retrieve a row.
- AMP_SNAPPY: The rows serialized using Ampool specific encoding and compressed using Snappy compression upon reaching the specified block size.…
