Greenmask is a powerful open-source utility that is designed for logical database backup dumping, obfuscation, and restoration. It offers extensive functionality for backup, anonymization, and data masking. Greenmask is written in pure Go and includes ported PostgreSQL libraries that allows for platform independence. This tool is stateless and does not require any changes to your database schema. It is designed to be highly customizable and backward-compatible with existing PostgreSQL...

CHB (Colony Hash Bucket) is a lightweight on-disk hash table designed for simplicity, predictability, and fast key-value lookups. Data is organized into a fixed-size bucket directory that maps hash values to chains of records stored in a compact append-only area. Each record contains a pointer to the next record in the chain, a key-length field with deletion flag support, and a fixed-size payload area.

pg_pathman is a PostgreSQL extension that provides high-performance partitioning support, developed by PostgresPro. It improves query planning and execution speed for partitioned tables by introducing advanced partition pruning and runtime optimization strategies. It’s ideal for large datasets that require fine-tuned partition control.

...It offers many other features such as pluggable serialization support, data item versioning and an SSD Optimized Read Write storage engine. Voldemort is not a relational database or an object database. It is essentially a big, distributed, persistent, fault-tolerant hash table. This doesn’t make it ideal for all applications but does offer unique advantages, such as the ability to read and write scale horizontally, and the ability to combine in memory caching with the storage system so that a separate caching tier is not required.

...Small Server - Simply multiply thread socket server. Nodes are some servers or hosts with fixed ip-port pairs. Nodes are configed with several known friends. Every node maintains a hash table-rbtree data structure that contains the node map information. Nodes can do fast sync with the friends to update this node map. MD4 signiture are used for fast sync. Every working node serves a range. Every range could have 3 nodes working at the same time. If a new node has join a node map, it can find its job automatically. ...

The Open Extract Processor (OEP) is a database ETL utility capable of merging/sorting/aggregating large partitioned database extracts. Native data files can be created from text files or from the accompanying MYSQL and Oracle import/export programs.
