`db.SetMaxOpenConns()` is highly recommended to limit the number of connection used by the application. There is no recommended limit number because it depends on application and MySQL server.
`db.SetMaxIdleConns()` is recommended to be set same to (or greater than) `db.SetMaxOpenConns()`. When it is smaller than `SetMaxOpenConns()`, connections can be opened and closed very frequently than you expect. Idle connections can be closed by the `db.SetConnMaxLifetime()`. If you want to close idle connections more rapidly, you can use `db.SetConnMaxIdleTime()` since Go 1.15.

`allowCleartextPasswords=true` allows using the [cleartext client side plugin](https://dev.mysql.com/doc/en/cleartext-pluggable-authentication.html) if required by an account, such as one defined with the [PAM authentication plugin](http://dev.mysql.com/doc/en/pam-authentication-plugin.html). Sending passwords in clear text may be a security problem in some configurations. To avoid problems if there is any possibility that the password would be intercepted, clients should connect to MySQL Server using a method that protects the password. Possibilities include [TLS / SSL](#tls), IPsec, or a private network.

`allowFallbackToPlaintext=true` acts like a `--ssl-mode=PREFERRED` MySQL client as described in [Command Options for Connecting to the Server](https://dev.mysql.com/doc/refman/5.7/en/connection-options.html#option_general_ssl-mode)

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.

All Unsigned database type names will be returned `UNSIGNED ` with `INT`, `TINYINT`, `SMALLINT`, `BIGINT`.
## `context.Context` Support
Go 1.8 added `database/sql` support for `context.Context`. This driver supports query timeouts and cancellation via contexts.

[![GoDoc](https://godoc.org/github.com/tidwall/btree?status.svg)](https://godoc.org/github.com/tidwall/btree)
An [efficient](#performance) [B-tree](https://en.wikipedia.org/wiki/B-tree) implementation in Go.
*Check out the [generics branch](https://github.com/tidwall/btree/tree/generics) if you want to try out btree with generic support for Go 1.18+*
An efficient [B-tree](https://en.wikipedia.org/wiki/B-tree) implementation in Go.
## Features
- `Copy()` method with copy-on-write support.
- Support for [Generics](#generics) (Go 1.18+).
- `Map` and `Set` types for ordered key-value maps and sets,
- Fast bulk loading for pre-ordered data using the `Load()` method.
- All operations are thread-safe.
- `Copy()` method with copy-on-write support.
- Thread-safe operations.
- [Path hinting](PATH_HINT.md) optimization for operations with nearby keys.
## Installing
## Using
To start using btree, install Go and run `go get`:
To start using this package, install Go and run:
```sh
$ go get -u github.com/tidwall/btree
$ go get github.com/tidwall/btree
```
## Usage
## B-tree types
This package includes the following types of B-trees:
- [`btree.Map`](#btreemap):
A fast B-tree for storing ordered key value pairs.
Go 1.18+
- [`btree.Set`](#btreeset):
Like `Map`, but only for storing keys.
Go 1.18+
- [`btree.BTreeG`](#btreegeneric):
A feature-rich B-tree for storing data using a custom comparator.
Go 1.18+
- [`btree.BTree`](#btreebtree):
Like `BTreeG` but uses the `interface{}` type for data. Backwards compatible.
Go 1.16+
### btree.Map
```go
// Basic
Set(key, value) // insert or replace an item
Get(key, value) // get an existing item
Delete(key) // delete an item
Len() // return the number of items in the map
// Iteration
Scan(iter) // scan items in ascending order
Reverse(iter) // scan items in descending order
Ascend(key, iter) // scan items in ascending order that are >= to key
Descend(key, iter) // scan items in descending order that are <= to key.
Iter() // returns a read-only iterator for for-loops.
// Array-like operations
GetAt(index) // returns the item at index
DeleteAt(index) // deletes the item at index
// Bulk-loading
Load(key, value) // load presorted items into tree
```
#### Example
```go
package main

func main() {
// create a map

users.Set("user:4", "Andrea")

users.Set("user:2", "Andy")
users.Set("user:1", "Jane")
users.Set("user:5", "Janet")
users.Set("user:3", "Steve")
// Iterate over the maps and print each user
users.Scan(func(key, value string) bool {
fmt.Printf("%s %s\n", key, value)
return true
})
fmt.Printf("\n")
// Delete a couple
users.Delete("user:5")
users.Delete("user:1")
// print the map again
users.Scan(func(key, value string) bool {
fmt.Printf("%s %s\n", key, value)
return true

## Operations
### Basic
```
Get(item) # get an existing item
Set(item) # insert or replace an existing item
Delete(item) # delete an item
Len() # return the number of items in the btree
```
### Iteration
```
Ascend(pivot, iter) # scan items in ascending order starting at pivot.
Descend(pivot, iter) # scan items in descending order starting at pivot.
Iter() # returns a read-only iterator for for-loops.
```
### Queues
```
Min() # return the first item in the btree
Max() # return the last item in the btree
PopMin() # remove and return the first item in the btree
PopMax() # remove and return the last item in the btree
```
### Bulk loading
```
Load(item) # load presorted items into tree
```
### Path hints
```
SetHint(item, *hint) # insert or replace an existing item
GetHint(item, *hint) # get an existing item
DeleteHint(item, *hint) # delete an item
```
### Array-like operations
```
GetAt(index) # returns the value at index
DeleteAt(index) # deletes the item at index
```
## Performance
This implementation was designed with performance in mind.
The following benchmarks were run on my 2019 Macbook Pro (2.4 GHz 8-Core Intel Core i9) using Go 1.17.3. The items are simple 8-byte ints.
- `google`: The [google/btree](https://github.com/google/btree) package
- `tidwall`: The [tidwall/btree](https://github.com/tidwall/btree) package
- `go-arr`: Just a simple Go array
