2015-08-20: Go Workshop Notes

• Workshop run by Bill Kennedy
• Course materials available at https://github.com/ardanstudios/gotraining
• This was a one-day distillation of the full 3-day course

Variables and Types

• Type gives the compiler two things: size + representation. The compiler guarantees these types

func join(gs []grid) grid {
	n := int(math.Sqrt(float64(len(gs))))  // Number of subgrids across/down the new grid
	sgn := len(gs[0])                      // Number of values on one side of a subgrid
	cg := newGridBySize(n * sgn)           // The new, combined grid to populate

	// Add each subgrid to the new, combined grid.
	for i, g := range gs {
		// Calculate the position of the top-left of the subgrid once placed in
		// the new, combined grid. We use this plus the offset within the subgrid
		// to place the values in the combined grid.

Value assignment

var s1 string         // a new string identifer with its zero value ("")
var s2 string = "foo" // an identifer with a non-zero value
var i1 int            // an int identifer with its zero value (0)
var i2 int = 42       // an int identifer with a non-zero value

Alvin Richards: MongoDB

• Trade-off: scale vs. functionality. MongoDB tries to have good functionality and good scalability.
• Auto-sharding to maintain equilibrium between shards
• Scalable datastore != scalable application: use of datastore may still be non-scalable (e.g. many queries across all shards)
• Get low latency by ensuring shard data is always in memory: datastore
