Functions

func EnableAuditSyslog

func ExpireTableData 

func ExpireTableData(tableName string, timestampColumn string) error

func ForgetInstance 

func ForgetInstance(tabletAlias string) error

ForgetInstance removes an instance entry from the vtorc backed database. It may be auto-rediscovered through topology or requested for discovery by multiple means.

func ForgetLongUnseenInstances 

func ForgetLongUnseenInstances() error

ForgetLongUnseenInstances will remove entries of all instances that have long since been last seen.

func GetDatabaseState added in v0.20.0 

func GetDatabaseState() (string, error)

GetDatabaseState takes the snapshot of the database and returns it.

func GetDurabilityPolicy 

func GetDurabilityPolicy(keyspace string) (reparentutil.Durabler, error)

GetDurabilityPolicy gets the durability policy for the given keyspace.

func GetKeyspaceShardName added in v0.16.0 

func GetKeyspaceShardName(tabletAlias string) (keyspace string, shard string, err error)

GetKeyspaceShardName gets the keyspace shard name for the given instance key

func InitializeTMC added in v0.19.4 

func InitializeTMC() tmclient.TabletManagerClient

InitializeTMC initializes the tablet manager client to use for all VTOrc RPC calls.

func InstanceIsForgotten 

func InstanceIsForgotten(tabletAlias string) bool

func MajorVersion 

func MajorVersion(version string) []string

MajorVersion returns a MySQL major version number (e.g. given "5.5.36" it returns "5.5")

func ReadInstanceClusterAttributes 

func ReadInstanceClusterAttributes(instance *Instance) (err error)

ReadInstanceClusterAttributes will return the cluster name for a given instance by looking at its primary and getting it from there. It is a non-recursive function and so-called-recursion is performed upon periodic reading of instances.

func ReadKeyspace 

func ReadKeyspace(keyspaceName string) (*topo.KeyspaceInfo, error)

ReadKeyspace reads the vitess keyspace record.

func ReadOutdatedInstanceKeys 

func ReadOutdatedInstanceKeys() ([]string, error)

ReadOutdatedInstanceKeys reads and returns keys for all instances that are not up to date (i.e. pre-configured time has passed since they were last checked) or the ones whose tablet information was read but not the mysql information. This could happen if the durability policy of the keyspace wasn't available at the time it was discovered. This would lead to not having the record of the tablet in the database_instance table. We also check for the case where an attempt at instance checking has been made, that hasn't resulted in an actual check! This can happen when TCP/IP connections are hung, in which case the "check" never returns. In such case we multiply interval by a factor, so as not to open too many connections on the instance.

func ReadShardPrimaryInformation added in v0.18.0 

func ReadShardPrimaryInformation(keyspaceName, shardName string) (primaryAlias string, primaryTimestamp string, err error)

ReadShardPrimaryInformation reads the vitess shard record and gets the shard primary alias and timestamp.

func SaveKeyspace(keyspace *topo.KeyspaceInfo) error

SaveKeyspace saves the keyspace record against the keyspace name.

func SaveShard added in v0.18.0 

func SaveShard(shard *topo.ShardInfo) error

SaveShard saves the shard record against the shard name.

func SaveTablet 

func SaveTablet(tablet *topodatapb.Tablet) error

SaveTablet saves the tablet record against the instanceKey.

func SnapshotTopologies 

func SnapshotTopologies() error

SnapshotTopologies records topology graph for all existing topologies

func UpdateInstanceLastAttemptedCheck 

func UpdateInstanceLastAttemptedCheck(tabletAlias string) error

UpdateInstanceLastAttemptedCheck updates the last_attempted_check timestamp in the vtorc backed database for a given instance. This is used as a failsafe mechanism in case access to the instance gets hung (it happens), in which case the entire ReadTopology gets stuck (and no, connection timeout nor driver timeouts don't help. Don't look at me, the world is a harsh place to live in). And so we make sure to note down *before* we even attempt to access the instance; and this raises a red flag when we wish to access the instance again: if last_attempted_check is *newer* than last_checked, that's bad news and means we have a "hanging" issue.

func UpdateInstanceLastChecked 

func UpdateInstanceLastChecked(tabletAlias string, partialSuccess bool) error

UpdateInstanceLastChecked updates the last_check timestamp in the vtorc backed database for a given instance

func ValidSecondsFromSeenToLastAttemptedCheck 

func ValidSecondsFromSeenToLastAttemptedCheck() uint

ValidSecondsFromSeenToLastAttemptedCheck returns the maximum allowed elapsed time between last_attempted_check to last_checked before we consider the instance as invalid.

func WriteInstance 

func WriteInstance(instance *Instance, instanceWasActuallyFound bool, lastError error) error

WriteInstance stores an instance in the vtorc backend
