####SQL worker pool around sqlx in Go.
#####Usage:
ws := 10 // 10 workers/connections.
qlen := 20 // 20 channel queue length before block.
pool, err := pgwp.Connect("postgres", "connection string", ws, qlen)
// err check
var list []Item
pool.Select(&list, "SELECT * FROM people WHERE name=$1 LIMIT 10", "lisa" )

Types ¶
type ConnectFunc ¶
ConnectFunc type is called when a new connection is required.
type Pool ¶
type Pool struct {
// contains filtered or unexported fields
}
Pool type contains all workers with his respectives connections.
func Connect ¶
Connect handle sqlx.Connect function. Receives workers and queue size.
DEPRECATED. Use Open func.
func Open ¶
func Open(connectionFunc ConnectFunc, workers, queue int) (*Pool, error)
Open return a new pool. Receive a database connection function for later reuse.
workers define number of connections open to database. queue defines length channel for queries before block. It's useful for control over application demand.
type ResultErr ¶
type ResultErr struct {
Error error
}
ResultErr satisfies sql.Result
It's used when a timeout occurs
func (*ResultErr) LastInsertId ¶
LastInsertId satisfies sql.Result
func (*ResultErr) RowsAffected ¶
RowsAffected satisfies sql.Result
