Syntax
getClusterChunksStatus()
Details
Return the metadata about all database chunks (file chunks and tablet chunks) on the data nodes in a cluster. It can be executed only on a controller.
Return a table containing the following columns:
chunkId: the chunk ID
file: the chunk path
size: The disk space occupied by the file chunk (in Bytes). Return 0 for a tablet chunk. Use
getTabletsMetato check the disk usage of a tablet chunk.version: version number
vcLength: length of the version chain
versionChain: the version chain
state: the status of the chunk. It can be
CONSTRUCTING: in transaction;
RECOVERING: recovering;
COMPLETE: transaction completed
replicas: distribution of replicas
replicaCount: the number of replicas
lastUpdated: lastUpdated: the timestamp of the latest update. Please note that lastUpdated column is supported since version 1.30.20. For a chunk created before version 1.30.20, it returns a NULL value.
permission: the chunk permission. It can be READ_ONLY and READ_WRITE (default). Chunks that are being transferred or stored in S3 are READ_ONLY.
For READ_ONLY chunks:
(1) Data cannot be appended or updated. Only drop operations can be performed to delete records. Transaction is supported in the READ_ONLY chunks (except for those stored in S3).
(2) Operations such as recovery and rebalance cannot be performed.
