HandlerSocket is a NoSQL plugin for MySQL that runs as a daemon inside the mysqld process, accepting TCP connections and executing simple CRUD operations on tables without SQL parsing. It bypasses the SQL layer for much lower CPU, disk, and network overhead in some workloads.

Use cases

• get key-value style reads from MySQL without SQL overhead
• run fast CRUD operations on MySQL tables from a NoSQL client
• reduce CPU usage for high-volume MySQL point queries
• batch many client requests against MySQL efficiently
• use MySQL as a NoSQL data store with a compact protocol
• connect to MySQL from C++, Perl, PHP, Java, Python, or Ruby clients

When to choose

• you need very high-throughput simple lookups or writes on existing MySQL tables
• you want NoSQL-style access while keeping data in MySQL with ACID storage
• SQL parsing overhead is your bottleneck for point queries

When to avoid

• you need complex queries, joins, or SQL features
• you are not on GNU/Linux
• you want an actively developed project - development has largely stalled
• you prefer modern alternatives like MySQL's built-in memcached plugin or dedicated NoSQL stores
