Types

type Cache 

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

func New 

func New(namespace string, setName string, client *as.Client, timeToLiveInSec uint32, options ...interface{}) (*Cache, error)

func (*Cache) AddValues 

func (a *Cache) AddValues(ctx context.Context, entry *cache.Entry, values []interface{}) error

func (a *Cache) AsSource(ctx context.Context, entry *cache.Entry) (cache.Source, error)

func (*Cache) AssignRows 

func (a *Cache) AssignRows(entry *cache.Entry, rows *sql.Rows) error

func (*Cache) Close 

func (a *Cache) Close(ctx context.Context, entry *cache.Entry) error

func (*Cache) Delete 

func (a *Cache) Delete(ctx context.Context, entry *cache.Entry) error

func (*Cache) Get 

func (a *Cache) Get(ctx context.Context, SQL string, args []interface{}, options ...interface{}) (*cache.Entry, error)

func (*Cache) IndexBy 

func (a *Cache) IndexBy(ctx context.Context, db *sql.DB, column, SQL string, args []interface{}, options ...interface{}) (int, error)

func (*Cache) IndexByWithResult added in v0.24.0 

func (a *Cache) IndexByWithResult(ctx context.Context, db *sql.DB, column, SQL string, args []interface{}, options ...interface{}) (*cache.IndexByResult, error)

func (*Cache) Rollback 

func (a *Cache) Rollback(ctx context.Context, entry *cache.Entry) error

func (*Cache) UpdateType 

func (a *Cache) UpdateType(ctx context.Context, entry *cache.Entry, args []interface{}) (bool, error)

type Config added in v0.26.0 

type Config struct {
	Provider string
	Location string
	Identity string
	TTL      time.Duration
	Timeout  TimeoutConfig
	// FailedRequestLimit is the tolerated number of consecutive failed native
	// record operations. A lookup can perform both lazy and warmup operations.
	FailedRequestLimit int
	ResetFailuresInMs  int
}

Config describes one configured cache. Provider is aerospike://host:port/namespace; Location is the set name. Identity scopes native query keys within that set. It must distinguish views using different connectors even when SQL matches.

type Errors 

type Errors struct {
	sync.Mutex
	// contains filtered or unexported fields
}

func (*Errors) Add 

func (e *Errors) Add(err error)

func (*Errors) Err 

func (e *Errors) Err() error

type FailureHandler added in v0.2.0 

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

FailureHandler temporarily bypasses cache reads after consecutive failures. Close stops its reset timer and prevents further timers from being scheduled.

func NewFailureHandler added in v0.2.0 

func NewFailureHandler(limit int64, resetAfter *time.Duration) *FailureHandler

func (*FailureHandler) Close added in v0.2.0 

func (f *FailureHandler) Close() error

func (*FailureHandler) HandleFailure added in v0.2.0 

func (f *FailureHandler) HandleFailure()

func (*FailureHandler) HandleSuccess added in v0.2.0 

func (f *FailureHandler) HandleSuccess()

func (*FailureHandler) IsProbing added in v0.2.0 

func (f *FailureHandler) IsProbing() bool

type IndexSource 

type IndexSource interface {
	Close() error
	Index(value interface{}) (*indexedValue, error)
	ColumnIndex() int
	Count() int
}

func NewIndexSource 

func NewIndexSource(aCache *Cache, column string, ordered bool, fields []*cache.Field, url string, metaBin as.BinMap) (IndexSource, error)

type MultiReader 

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

func NewMultiReader 

func NewMultiReader(matcher *cache.ParmetrizedQuery) *MultiReader

func (*MultiReader) AddReader 

func (m *MultiReader) AddReader(reader *Reader)

func (*MultiReader) Close 

func (m *MultiReader) Close() error

func (*MultiReader) Read 

func (m *MultiReader) Read(target []byte) (int, error)

Read and ReadLine consume the same windowed row stream. Buffering one fragment preserves forward progress for callers using buffers smaller than a row.

func (*MultiReader) ReadLine 

func (m *MultiReader) ReadLine() ([]byte, bool, error)

type OrderedSource 

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

func NewOrderedSource 

func NewOrderedSource(aCache *Cache, column string, url string, metaBin as.BinMap, index int) *OrderedSource

func (*OrderedSource) Close 

func (o *OrderedSource) Close() error

func (*OrderedSource) ColumnIndex 

func (o *OrderedSource) ColumnIndex() int

func (*OrderedSource) Count added in v0.24.0 

func (o *OrderedSource) Count() int

func (*OrderedSource) Index 

func (o *OrderedSource) Index(value interface{}) (*indexedValue, error)

type Placeholders 

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

func NewPlaceholders 

func NewPlaceholders(columnIndex int, fields []*cache.Field) *Placeholders

func (*Placeholders) ColumnValue 

func (p *Placeholders) ColumnValue() (interface{}, bool)

func (*Placeholders) CreatePlaceholderAt 

func (p *Placeholders) CreatePlaceholderAt(i int)

func (*Placeholders) ScanPlaceholders 

func (p *Placeholders) ScanPlaceholders() []interface{}

func (*Placeholders) Values 

func (p *Placeholders) Values() []interface{}

type Pool added in v0.26.0 

type Pool struct {
	ClientPolicy *as.ClientPolicy
	// contains filtered or unexported fields
}

Pool owns configured cache clients and failure timers for a service lifetime. The zero value is ready to use. Call Close after all reads and warmups drain, including on failed startup. Injected caches/clients are never adopted. ClientPolicy controls connection setup and the native per-node connection pool; set it before first use and do not mutate it while the Pool is in use.

func (*Pool) Close added in v0.26.0 

func (p *Pool) Close() error

Close is idempotent. It is a service lifetime operation, distinct from Cache.Close which finalizes a single cache entry. No new clients can be opened afterward.

func (*Pool) NewCache added in v0.26.0 

func (p *Pool) NewCache(config Config) (*Cache, error)

NewCache returns the native cache service, sharing clients by seed endpoint and cache policy by exact configuration. Failed connects are returned to the caller; no background retry or client is retained after a failed connect.

type Reader 

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

func (*Reader) Close 

func (r *Reader) Close() error

func (*Reader) Read 

func (r *Reader) Read(b []byte) (int, error)

func (*Reader) ReadLine

type RecordMatched 

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

type SingleSource 

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

func NewSingleSource 

func NewSingleSource(aCache *Cache, column string, url string, metaBin as.BinMap) *SingleSource

func (s *SingleSource) Index(value interface{}) (*indexedValue, error)

type Source 

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

func (*Source) Close 

func (s *Source) Close(ctx context.Context) error

func (*Source) ConvertColumns 

func (s *Source) ConvertColumns() ([]io.Column, error)

func (*Source) Err added in v0.14.0

func (*Source) Next 

func (s *Source) Next() bool

func (*Source) Rollback

func (*Source) XTypes 

func (s *Source) XTypes() []*xunsafe.Type

type TimeoutConfig 

type TimeoutConfig struct {
	MaxRetries            int
	SocketTimeoutMs       int
	TotalTimeoutMs        int
