Caching involves storing frequently accessed data temporarily to speed up retrieval and reduce load on the main data source.
Data Partitioning divides a database into smaller pieces to improve performance and scalability.
Proxies act as intermediaries between clients and servers to enhance security, privacy, and performance.
Redundancy involves duplicating critical system components to ensure reliability and availability in case of failures.
The PACELC theorem balances availability vs consistency during partitions and latency vs consistency otherwise.
Databases store, organize, and manage data for efficient retrieval and manipulation.
Indexes optimize data retrieval speed by creating quick access paths to specific data in a database.
Bloom Filters are space-efficient data structures used to test whether an element is likely in a set, with possible false positives.
Quorum is the minimum number of nodes required to agree on a decision in a distributed system to ensure consistency.
Heartbeats are regular signals sent between system components to monitor their status and ensure they are operational.
A checksum is a calculated value used to verify the integrity of data by detecting errors or corruption during transmission or storage.
