Using memtier_benchmark on AWS c5.4xlarge (16 vCPU):
For those interested in the technical details of KeyDB, here are some key specifications:
When datasets grow into terabytes, RAM costs become prohibitive. The KeyDB-Flash engine extends the storage layer to non-volatile memory. keydb eng
KeyDB is ideal for scenarios that require high-performance, in-memory data structures:
To avoid locking overhead on read-heavy workloads, KeyDB implements for read operations. Using memtier_benchmark on AWS c5
Unlike Redis’s asynchronous replication (Master-Replica), KeyDB supports .
The KeyDB Engine introduces a fully multithreaded network and query execution architecture. Multiple threads handle network I/O, packet parsing, and command execution simultaneously. 2. Multi-Version Concurrency Control (MVCC) Unlike Redis’s asynchronous replication (Master-Replica)
: Its multi-threaded nature handles complex operations (like SINTER or SUNION on large sets) without "freezing" the database for other users.
