Functions

func KeepConnection 

func KeepConnection(err error) bool

Should connection be put back into pool.

func NewAerospikeError 

func NewAerospikeError(code ResultCode, messages ...string) error

NewAerospikeError generates a new AerospikeError instance. If no message is provided, the result code will be translated into the default error message automatically. To be able to check for error type, you could use the following: 

if aerr, ok := err.(AerospikeError); ok {
    errCode := aerr.ResultCode()
    errMessage := aerr.Error()
}

func ResultCodeToString 

func ResultCodeToString(resultCode ResultCode) string

Return result code as a string.

func TTL 

func TTL(secsFromCitrusLeafEpoc uint32) uint32

TTL converts an Expiration time from citrusleaf epoc to TTL in seconds.

Types

type AerospikeError 

type AerospikeError struct {
	// contains filtered or unexported fields
}

AerospikeError implements error interface for aerospike specific errors. All errors returning from the library are of this type. Errors resulting from Go's stdlib are not translated to this type, unless they are a net.Timeout error.

func (AerospikeError) InDoubt added in v1.32.0 

func (ase AerospikeError) InDoubt() bool

InDoubt determines if a write transaction may have completed or not.

func (*AerospikeError) MarkInDoubt added in v1.32.0 

func (ase *AerospikeError) MarkInDoubt()

MarkInDoubt marks an error as in doubt.

func (AerospikeError) ResultCode 

func (ase AerospikeError) ResultCode() ResultCode

ResultCode returns the ResultCode from AerospikeError object.

func (*AerospikeError) SetInDoubt added in v1.32.0 

func (ase *AerospikeError) SetInDoubt(isRead bool, commandSentCounter int)

SetInDoubt sets whether it is possible that the write transaction may have completed even though this error was generated. This may be the case when a client error occurs (like timeout) after the command was sent to the server.

type BufferPool added in v1.0.1 

type BufferPool struct {
	// contains filtered or unexported fields
}

BufferPool implements a specialized buffer pool. Pool size will be limited, and each buffer size will be constrained to the init and max buffer sizes.

func NewBufferPool added in v1.0.1 

func NewBufferPool(poolSize, initBufferSize, maxBufferSize int) *BufferPool

NewBufferPool creates a new buffer pool. New buffers will be created with size and capacity of initBufferSize. If cap(buffer) is larger than maxBufferSize when it is put back in the buffer, it will be thrown away. This will prevent unwanted memory bloat and set a deterministic maximum-size for the pool which will not be exceeded.

func (*BufferPool) Get added in v1.0.1 

func (bp *BufferPool) Get() (res []byte)

Get returns a buffer from the pool. If pool is empty, a new buffer of size initBufSize will be created and returned.

func (*BufferPool) Put added in v1.0.1 

func (bp *BufferPool) Put(buf []byte)

Put will put the buffer back in the pool, unless cap(buf) is bigger than initBufSize, in which case it will be thrown away

type Message 

type Message struct {
	MessageHeader

	Data []byte
}

func NewMessage 

func NewMessage(mtype messageType, data []byte) *Message

NewMessage generates a new Message instance.

func (*Message) Resize 

func (msg *Message) Resize(newSize int64) error

Resize changes the internal buffer size for the message.

func (*Message) Serialize 

func (msg *Message) Serialize() []byte

Serialize returns a byte slice containing the message.

type MessageHeader 

type MessageHeader struct {
	Version uint8
	Type    uint8
	DataLen [6]byte
}

func (*MessageHeader) Length 

func (msg *MessageHeader) Length() int64

Length returns the length of the message

type Pool added in v1.0.1 

type Pool struct {

	// New will create a new object
	New func(params ...interface{}) interface{}
	// IsUsable checks if the object polled from the pool is still fresh and usable
	IsUsable func(obj interface{}, params ...interface{}) bool
	// CanReturn checkes if the object is eligible to go back to the pool
	CanReturn func(obj interface{}) bool
	// Finalize will be called when an object is not eligible to go back to the pool.
	// Usable to close connections, file handles, ...
	Finalize func(obj interface{})
	// contains filtered or unexported fields
}

Pool implements a general purpose fixed-size pool.

func NewPool added in v1.0.1 

func NewPool(poolSize int) *Pool

NewPool creates a new fixed size pool.

func (*Pool) Get added in v1.0.1 

func (bp *Pool) Get(params ...interface{}) interface{}

Get returns an element from the pool. If the pool is empty, or the returned element is not usable, nil or the result of the New function will be returned

func (*Pool) Put added in v1.0.1 

func (bp *Pool) Put(obj interface{})

Put will add the elem back to the pool, unless the pool is full.

type ResultCode 

type ResultCode int

ResultCode signifies the database operation error codes. The positive numbers align with the server side file proto.h.
