Types ¶
type Config ¶
type Config struct {
// contains filtered or unexported fields
}
Config provides access to the persistent configuration stored in the database. It uses an RWLocker to ensure thread-safe access to configuration keys.
func (*Config) GetCDCAvg ¶ added in v0.9.2
GetCDCAvg returns the CDC average chunk size from the configuration.
func (*Config) GetCDCEnabled ¶ added in v0.9.2
GetCDCEnabled returns the CDC enabled flag from the configuration.
func (*Config) GetCDCMax ¶ added in v0.9.2
GetCDCMax returns the CDC maximum chunk size from the configuration.
func (*Config) GetCDCMin ¶ added in v0.9.2
GetCDCMin returns the CDC minimum chunk size from the configuration.
func (*Config) GetClusterUUID ¶
GetClusterUUID returns the cluster UUID from the configuration.
func (*Config) GetSecretKey ¶ added in v0.7.0
GetSecretKey returns the secret key from the configuration.
func (*Config) SetCDCAvg ¶ added in v0.9.2
SetCDCAvg stores the CDC average chunk size in the configuration.
func (*Config) SetCDCEnabled ¶ added in v0.9.2
SetCDCEnabled stores the CDC enabled flag in the configuration.
func (*Config) SetCDCMax ¶ added in v0.9.2
SetCDCMax stores the CDC maximum chunk size in the configuration.
func (*Config) SetCDCMin ¶ added in v0.9.2
SetCDCMin stores the CDC minimum chunk size in the configuration.
func (*Config) SetClusterUUID ¶
SetClusterUUID stores the cluster UUID in the configuration.
func (*Config) SetSecretKey ¶ added in v0.7.0
SetSecretKey stores the secret key in the configuration.
func (*Config) ValidateOrStoreCDCConfig ¶ added in v0.9.2
func (c *Config) ValidateOrStoreCDCConfig( ctx context.Context, enabled bool, minSize, avgSize, maxSize uint32, ) error
ValidateOrStoreCDCConfig validates CDC configuration against stored values or stores them if not yet configured. If CDC is disabled and no config exists, returns nil (no-op). If CDC is enabled and no config exists, stores all 4 values. If config exists, validates that enabled flag matches and all values are identical. If CDC was previously enabled (config exists) but now disabled, returns an error.
