RecoveryProgress (starrocks-bdb-je 18.3.17 API)

java.lang.Object
- java.lang.Enum<RecoveryProgress>
- - com.sleepycat.je.RecoveryProgress

All Implemented Interfaces:

Serializable, Comparable<RecoveryProgress>
```
public enum RecoveryProgress
extends Enum<RecoveryProgress>
```
Describes the different phases of initialization that be executed when an Environment is instantiated. Meant to be used in conjunction with a ProgressListener that is configured through EnvironmentConfig.setRecoveryProgressListener(com.sleepycat.je.ProgressListener<com.sleepycat.je.RecoveryProgress>) to monitor the cost of environment startup

Since:

5.0

Enum Constant Summary

Enum Constants
Enum Constant and Description
`BECOME_CONSISTENT` For replicated systems only: if a replica, process enough of the replication stream so that the environment fulfills the required consistency policy, as defined by parameters passed to the ReplicatedEnvironment constructor.
`CKPT` Perform a checkpoint to make all the work of this environment startup persistent, so it is not repeated in future startups.
`FIND_END_OF_LOG` Find the last valid entry in the database log.
`FIND_LAST_CKPT` Find the last complete checkpoint in the database log.
`FIND_MASTER` For replicated systems only: locate the master of the replication group by querying others in the group, and holding an election if necessary.
`FINISH_VERIFICATION` Finish verifying the data file checksums, in cases where this takes longer than other parts of the single-threaded recovery process.
`POPULATE_EXPIRATION_PROFILE` Populate internal metadata which stores information about the expiration time/data windows (histogram) of each log file, for efficient log cleaning.
`POPULATE_UTILIZATION_PROFILE` Populate internal metadata which stores information about the utilization level of each log file, for efficient log cleaning.
`READ_DATA_INFO` Read log entries that pertain to the database indices.
`READ_DBMAP_INFO` Read log entries that pertain to the database map, which is an internal index of all databases.
`RECOVERY_FINISHED` Basic recovery is completed, and the environment is able to service operations.
`REDO_DATA_INFO` Redo log entries that pertain to the database indices.
`REDO_DATA_RECORDS` Repeat committed data operations, such as inserts, updates and deletes.
`REDO_DBMAP_INFO` Redo log entries that pertain to the database map, which is an internal index of all databases.
`REDO_DBMAP_RECORDS` Redo committed database creation, deletion and truncations.
`REMOVE_TEMP_DBS` Remove temporary databases created by the application that are no longer valid.
`UNDO_DATA_RECORDS` Rollback uncommitted data operations, such as inserts, updates and deletes.
`UNDO_DBMAP_RECORDS` Rollback uncommitted database creation, deletion and truncations.
