MapOrder defines map storage order.

INVERTED mapReturnType }{ 0, 1, 2, 3, 4, 5, 6, 7, 8, 13, 16, 17, 0x10000, }
MapReturnType defines the map return type. Type of data to return when selecting or removing items from the map.

MapWriteMode should only be used for server versions < 4.3. MapWriteFlags are recommended for server versions >= 4.3.
var UseNativeBoolTypeInReflection = false
UseNativeBoolTypeInReflection determines if Boolean values should be directly translated to native Boolean type in reflection API introduced in server version 5.6+. By default it keeps the old behavior, but can be set to true to opt in.
Deprecated: Will be removed in the next major version.

Errors resulting from Go's stdlib are not translated to this type, unless they are a net.Timeout error. Refer to errors_test.go for examples. To be able to check for error type, you could use the idiomatic errors.Is and errors.As patterns:
if errors.Is(err, as.ErrTimeout) { ... }
or
if errors.Is(err, &as.AerospikeError{ResultCode: ast.PARAMETER_ERROR}) { ... }

func (clnt *Client) ScanNodeObjects(apolicy *ScanPolicy, node *Node, objChan interface{}, namespace string, setName string, binNames ...string) (*Recordset, Error)
ScanNodeObjects reads all records in specified namespace and set for one node only, and marshalls the results into the objects of the provided channel in Recordset. If the policy is nil, the default relevant policy will be used. The resulting records will be marshalled into the objChan. objChan will be closed after all the records are read.
func (*Client) ScanPartitionObjects ¶
func (clnt *Client) ScanPartitionObjects(apolicy *ScanPolicy, objChan interface{}, partitionFilter *PartitionFilter, namespace string, setName string, binNames ...string) (*Recordset, Error)

Otherwise, server nodes are read sequentially. If partitionFilter is nil, all partitions will be scanned. If the policy is nil, the default relevant policy will be used. This method is only supported by Aerospike 4.9+ servers.
func (*Client) ScanPartitions ¶
func (clnt *Client) ScanPartitions(apolicy *ScanPolicy, partitionFilter *PartitionFilter, namespace string, setName string, binNames ...string) (*Recordset, Error)

Otherwise, server nodes are read sequentially. If partitionFilter is nil, all partitions will be scanned. If the policy is nil, the default relevant policy will be used. This method is only supported by Aerospike 4.9+ servers.

SetQuotas sets maximum reads/writes per second limits for a role. If a quota is zero, the limit is removed. Quotas require server security configuration "enable-quotas" to be set to true. Pass 0 for quota values for no limit.
func (*Client) SetWhitelist ¶
func (clnt *Client) SetWhitelist(policy *AdminPolicy, roleName string, whitelist []string) Error

func (*Client) Truncate ¶
func (clnt *Client) Truncate(policy *InfoPolicy, namespace, set string, beforeLastUpdate *time.Time) Error
Truncate removes records in specified namespace/set efficiently. This method is many orders of magnitude faster than deleting records one at a time. Works with Aerospike Server versions >= 3.12. This asynchronous server call may return before the truncation is complete. The user can still write new records after the server call returns because new records will have last update times greater than the truncate cutoff (set at the time of truncate call). For more information, See https://www.aerospike.com/docs/reference/info#truncate
func (*Client) WarmUp ¶
WarmUp fills the connection pool with connections for all nodes. This is necessary on startup for high traffic programs. If the count is <= 0, the connection queue will be filled. If the count is more than the size of the pool, the pool will be filled. Note: One connection per node is reserved for tend operations and is not used for transactions.

ListReturnTypeNone ListReturnType = 0 // ListReturnTypeIndex will return index offset order. // 0 = first key // N = Nth key // -1 = last key ListReturnTypeIndex ListReturnType = 1 // ListReturnTypeReverseIndex will return reverse index offset order. // 0 = last key // -1 = first key ListReturnTypeReverseIndex ListReturnType = 2 // ListReturnTypeRank will return value order. // 0 = smallest value // N = Nth smallest value // -1 = largest value ListReturnTypeRank ListReturnType = 3 // ListReturnTypeReverseRank will return reverse value order. // 0 = largest value // N = Nth largest value // -1 = smallest value ListReturnTypeReverseRank ListReturnType = 4 // ListReturnTypeCount will return count of items selected. ListReturnTypeCount ListReturnType = 5 // ListReturnTypeValue will return value for single key read and value list for range read. ListReturnTypeValue ListReturnType = 7 // ListReturnTypeExists returns true if count > 0. ListReturnTypeExists ListReturnType = 13 // ListReturnTypeInverted will invert meaning of list command and return values. For example: // ListOperation.getByIndexRange(binName, index, count, ListReturnType.INDEX | ListReturnType.INVERTED) // With the INVERTED flag enabled, the items outside of the specified index range will be returned. // The meaning of the list command can also be inverted. For example: // ListOperation.removeByIndexRange(binName, index, count, ListReturnType.INDEX | ListReturnType.INVERTED); // With the INVERTED flag enabled, the items outside of the specified index range will be removed and returned.

type MultiPolicy struct { BasePolicy // Maximum number of concurrent requests to server nodes at any point in time. // If there are 16 nodes in the cluster and maxConcurrentNodes is 8, then queries // will be made to 8 nodes in parallel. When a query completes, a new query will // be issued until all 16 nodes have been queried. // Default (0) is to issue requests to all server nodes in parallel. // 1 will to issue requests to server nodes one by one avoiding parallel queries. MaxConcurrentNodes int // MaxRecords approximates the number of records to return to the client. This number is divided by the // number of nodes involved in the query. The actual number of records returned // may be less than MaxRecords if node record counts are small and unbalanced across // nodes. // // This field is supported on server versions >= 4.9. // // Default: 0 (do not limit record count) MaxRecords int64 // RecordsPerSecond limits returned records per second (rps) rate for each server. // Will not apply rps limit if recordsPerSecond is zero (default). // Currently only applicable to a query without a defined filter.

RecordQueueSize int //= 50 // Indicates if bin data is retrieved. If false, only record digests are retrieved. IncludeBinData bool //= true; // RawCDT specifies that the value of the CDT fields (Maps and Lists) should not be unpacked/decoded. // This is only used internally by Aerospike for Backup purposes and should not be used by 3rd parties. RawCDT bool }

func NewMultiPolicy ¶
func NewMultiPolicy() *MultiPolicy
NewMultiPolicy initializes a MultiPolicy instance with default values. It disables TotalTimeout and sets MaxRetries. Set MaxRetries for non-aggregation queries with a nil filter on server versions >= 4.9. All other queries are not retried.
The latest servers support retries on individual data partitions. This feature is useful when a cluster is migrating and partition(s) are missed or incomplete on the first query attempt.
If the first query attempt misses 2 of 4096 partitions, then only those 2 partitions are retried in the next query attempt from the last key digest received for each respective partition. A higher default MaxRetries is used because it's wasteful to invalidate all query results because a single partition was missed.

}
