golang-db-sql-benchmark

A collection of benchmarks for popular Go database/SQL utilities

Libraries under test

database/sql SQL Execution Benchmarks:

BenchmarkPreparedStatementsNone - Runs simple queries without query arguments, so database/sql doesn't need to create a prepared statement

BenchmarkPreparedStatementsThrowaway - Runs queries with query arguments. database/sql must create and then throwaway a prepared statement each time

BenchmarkPreparedStatementsSingle - Runs queries with query arguments, but creates and reuses the a single prepared statement

Dbr/Sqlx/Gorp SQL Execution Benchmarks:

Each library under test has the same set of benchmarks, just replace Dbr in the examples with Sqlx or Gorp. Each one is run with varying number of rows, N.

BenchmarkDbrSelectIntsN - Select rows of integers into []int64's

BenchmarkDbrSelectAllN - Select rows into structs using no query arguments

BenchmarkDbrSelectAllWithArgsN - Select rows into structs using query arguments

Dbr/Squrrel SQL Building Benchamrks

Test building (but not executing) various SQL statements

BenchmarkBuilderDbrSimple - Simple SQL query with dbr

BenchmarkBuilderDbrComplex - Complex SQL query with dbr

BenchmarkBuilderSquirrelSimple - Simple SQL query with squirrel

BenchmarkBuilderSquirrelComplex - Complex SQL query with squirrel

Run yourself

Use the godep tool or manually install all libraries under test

Create db: mysql -e "create database golang_sql_benchmarks;"

Create schema: mysql golang_sql_benchmarks < structure.sql

Run: godep go test -bench=. -benchmem

You can set the MySQL DSN to use by setting the GOLANG_SQL_BENCHMARKS_DSN env var (defaults to root@unix(/var/run/mysqld/mysqld.sock)/golang_sql_benchmarks)
