Liquibase is a database schema change management tool and version control system designed to track, manage, and apply versioned database modifications. It functions as a SQL migration framework and DevOps automation utility that integrates database deployments into continuous delivery pipelines and build toolchains. The system enables precise rollbacks and drift detection by recording every modification made to a database schema. It supports the definition of database changes through structured changesets in XML, YAML, or JSON, as well as raw SQL scripts, to ensure consistent deployments acro

MongoDB Connector for Hadoop

Redisson is a Java client library for Redis and Valkey that provides a distributed data structure library, a distributed lock manager, and a distributed MapReduce framework. It enables application instances in a cluster to share state through thread-safe collections and objects. The project implements a JCache compliant caching layer for standardized data storage and retrieval. It also functions as a probabilistic data store, providing memory-efficient structures such as Bloom filters and HyperLogLog for high-volume data membership testing. The library covers distributed state management usi

Cassandra Java Client

Co-Process for backup/recovery, Token Management, and Centralized Configuration management for Cassandra.

Presto is a distributed SQL query engine designed for high-performance analytical processing across heterogeneous data sources. It functions as a data federation platform and massively parallel processing engine, allowing users to execute interactive queries against diverse storage systems without requiring data migration. By mapping remote metadata and structures to a unified relational namespace, it enables seamless cross-platform analysis through a standard SQL interface. The engine distinguishes itself through a pluggable connector architecture and a shared-nothing distributed processing

MongoDB River Plugin for ElasticSearch

Jedis is a Java library and database driver used to execute commands and manage data on Redis servers and distributed clusters. It functions as a network client that provides a low-level interface for manipulating data types, including JSON and vector sets. The project serves as a connection manager featuring automatic failover and token-based authentication to secure network connections. It manages data distribution across multiple nodes through cluster-aware topology mapping and handles connection failover to maintain service availability when a primary connection fails.
