### Connection pool and timeouts
The connection pool is managed by Go's database/sql package. For details on how to configure the size of the pool and how long connections stay in the pool see `*DB.SetMaxOpenConns`, `*DB.SetMaxIdleConns`, and `*DB.SetConnMaxLifetime` in the [database/sql documentation](https://golang.org/pkg/database/sql/). The read, write, and dial timeouts for each individual connection are configured with the DSN parameters [`readTimeout`](#readtimeout), [`writeTimeout`](#writetimeout), and [`timeout`](#timeout), respectively.
## `ColumnType` Support
This driver supports the [`ColumnType` interface](https://golang.org/pkg/database/sql/#ColumnType) introduced in Go 1.8, with the exception of [`ColumnType.Length()`](https://golang.org/pkg/database/sql/#ColumnType.Length), which is currently not supported.
## `context.Context` Support
Go 1.8 added `database/sql` support for `context.Context`. This driver supports query timeouts and cancellation via contexts.
See [context support in the database/sql package](https://golang.org/doc/go1.8#database_sql) for more details.
### `LOAD DATA LOCAL INFILE` support
For this feature you need direct access to the package. Therefore you must change the import path (no `_`):

### `time.Time` support
The default internal output type of MySQL `DATE` and `DATETIME` values is `[]byte` which allows you to scan the value into a `[]byte`, `string` or `sql.RawBytes` variable in your programm.
The default internal output type of MySQL `DATE` and `DATETIME` values is `[]byte` which allows you to scan the value into a `[]byte`, `string` or `sql.RawBytes` variable in your program.
However, many want to scan MySQL `DATE` and `DATETIME` values into `time.Time` variables, which is the logical opposite in Go to `DATE` and `DATETIME` in MySQL. You can do that by changing the internal output type from `[]byte` to `time.Time` with the DSN parameter `parseTime=true`. You can set the default [`time.Time` location](https://golang.org/pkg/time/#Location) with the `loc` DSN parameter.
