NCache Glossary
This resource provides clear, concise definitions and explanations to help you understand complex caching topics, specifically, caching in NCache.
List of Terms
The following is the list of terms that you need to understand in order to develop a further understanding of NCache.
Access Control List (ACL)
An access control list (ACL) consists of rules that determine whether access to specific digital environments is granted or denied. It is an essential element of Authentication and Authorization, NCache offers a detailed implementation that you can read about in the NCache Documentation. NCache uses LDAP for security, it offers two user types: Node Administrators (full cache control) and Cache Users (limited to API access) for this purpose. It's essential to maintain uniform security settings across cluster nodes to prevent any issues.ACID Transactions
ACID is an acronym representing four essential properties of a transaction: Atomicity, Consistency, Isolation, and Durability. When a database operation adheres to these ACID properties, it is called an ACID transaction. These properties ensure that these database operations are completed accurately, even in the event of errors, failures, or crashes. Systems that implement these operations are known as transactional systems. Atomicity prevents partial updates, Consistency synchronizes data across the cache and storage, Isolation allows concurrent transactions without conflicts, and Durability ensures committed changes are permanent even after failures. NCache upholds ACID properties to ensure reliable data handling.Active-Active Database (CRDB)
An Active-Active Database (CRDB) refers to a distributed database setup where multiple database nodes operate simultaneously in different locations, all serving read and write requests. This configuration ensures high availability, fault tolerance, and disaster recovery by replicating data in real-time across nodes. It enhances performance by allowing localized access while maintaining global data consistency.Active-Active Database Instance
An Active-Active Database Instance refers to a configuration in which multiple database instances operate simultaneously, allowing read and write operations on any instance of them. These instances are synchronized in real-time, ensuring data consistency and availability across multiple locations.Active-Passive Database Replication
Active-Active Database Replication is a setup where one database (active) handles all operations, while the other (passive) remains idle until the active one fails, at which point the passive takes over to maintain availability. NCache ensures such high data availability and data reliability through its distributed caching topologies, like Mirrored, Replicated, etc.Admin Console

This can lead to increased latency and access times as the data is retrieved from a slower storage layer. NCache helps minimize cache misses through its various synchronization mechanisms such as expiration, eviction, dependencies, loader, refresher, and more.Caching Best Practices
Caching best practices optimize cache performance by setting appropriate cache sizes, selecting effective eviction policies like LRU or LFU, and implementing cache invalidation to manage stale data. Compressing data maximizes efficiency, while monitoring cache performance helps fine-tune configurations. It's important to avoid over-caching by focusing on frequently accessed data and ensuring cache security to prevent unauthorized access.Caching Strategies
Caching Strategies are methods to manage how data is stored and accessed in a cache. They include Cache-aside, Read-through, Write-through, Write-behind, Refresh-ahead, and more. In NCache, they are referred to as Data Source Providers. These speak of a sequence of transparent read/write operations via Write-Through/Write-Behind and Read-Through/Write-Through caching on the data source. TheIReadThruProvider or IWriteThruProvider interfaces must be implemented in order to use these. These patterns are used depending on the application’s needs for data consistency, latency, and throughput.
CAP Theorem
CAP Theorem asserts that a distributed system can only guarantee two of the following three properties at the same time: Consistency (all nodes see the same data), Availability (every request gets a response), and Partition Tolerance (system functions despite network partitions).Causal Consistency
Causal Consistency ensures that operations are seen by all nodes in a distributed system in a manner that respects the causal relationships between them. In other words, if one operation causally influences another, then all nodes will see these operations in the same order. This allows for a more intuitive consistency model compared to strict consistency, while still providing a reliable ordering of operations.Change Data Capture (CDC)
Change Data Capture (CDC) is a technique used to track and capture changes made to data in a database, including insertions, updates, and deletions.
