Parameters:

vectorIndexConfig - the vector index configuration to add

Returns:

this VectorCollectionConfig instance

getVectorIndexConfigs

public List<VectorIndexConfig> getVectorIndexConfigs()

Parameters:

vectorIndexConfigs - The list of VectorIndexConfig instances to set.

getBackupCount

public int getBackupCount()

Returns the backupCount for this VectorCollection

Returns:

the backupCount for this VectorCollection

Since:

6.0

See Also:

• getAsyncBackupCount()

setBackupCount

public VectorCollectionConfig setBackupCount(int backupCount)

Number of synchronous backups. For example, if 1 is set as the backup count, then all entries of the vector collection will be copied to another JVM for fail-safety. 0 means no sync backup.

Parameters:

backupCount - the number of synchronous backups to set for this VectorCollection

Returns:

the updated VectorCollectionConfig

Since:

6.0

See Also:

• setAsyncBackupCount(int)

getAsyncBackupCount

public int getAsyncBackupCount()

Returns the asynchronous backup count for this VectorCollection.

Returns:

the asynchronous backup count

Since:

6.0

See Also:

• setBackupCount(int)

setAsyncBackupCount

public VectorCollectionConfig setAsyncBackupCount(int asyncBackupCount)

Sets the number of asynchronous backups. 0 means no backups.

Parameters:

asyncBackupCount - the number of asynchronous synchronous backups to set

Returns:

the updated VectorCollectionConfig

Throws:

IllegalArgumentException - if asyncBackupCount smaller than 0, or larger than the maximum number of backup or the sum of the backups and async backups is larger than the maximum number of backups

Since:

6.0

See Also:

• setBackupCount(int)
• getAsyncBackupCount()
