MarkLogic is a multi-model NoSQL database that provides advanced search and data integration capabilities. However, users may encounter issues such as database connection failures, indexing problems, query performance bottlenecks, security configuration errors, and cluster synchronization challenges. Troubleshooting these issues ensures a stable and efficient database environment.

PostgreSQL is a powerful, open-source relational database management system known for its extensibility, reliability, and compliance with SQL standards. However, users may encounter issues such as connection failures, slow queries, replication problems, configuration missteps, and data integrity concerns. Troubleshooting these problems ensures efficient and stable database performance.

ClickHouse is a high-performance, columnar database designed for real-time analytics. However, users often encounter challenges such as slow query performance, resource contention, schema design inefficiencies, replication failures, and incorrect data ingestion. Troubleshooting these issues ensures optimal database performance and reliability.

ArangoDB is a multi-model NoSQL database that supports document, key-value, and graph-based data storage. However, users often encounter challenges such as slow query performance, cluster synchronization failures, memory consumption issues, authentication errors, and replication inconsistencies. Troubleshooting these issues ensures optimal performance and data consistency.

InfluxDB is a high-performance time-series database widely used for real-time monitoring, analytics, and IoT applications. However, users often encounter issues such as high memory consumption, query inefficiencies, write failures, retention policy misconfigurations, and authentication problems. Troubleshooting these problems ensures optimal database performance and reliable data storage.

MariaDB is a popular open-source relational database management system (RDBMS) that is widely used for its high performance, reliability, and security features. However, users often encounter issues such as connection failures, slow queries, replication lag, data corruption, and memory overutilization. Troubleshooting these problems ensures a stable and efficient MariaDB database environment.

GraphDB is a high-performance graph database optimized for handling complex relationships and semantic queries using RDF (Resource Description Framework). However, users often face challenges such as slow query performance, incorrect SPARQL query results, transaction failures, data inconsistencies, and memory management issues. Troubleshooting these problems ensures efficient query execution and data integrity.

Apache Cassandra is a highly scalable, distributed NoSQL database designed for handling large volumes of data across multiple nodes. However, users often encounter issues such as node failures, high latency, read and write inconsistencies, compaction problems, and performance degradation under high load. Troubleshooting these issues ensures the stability and efficiency of Cassandra clusters.
