getTabletsMeta

getTabletsMeta([chunkPath],[tableName],[diskUsage=false],[top=124])

chunkPath (optional) is the DFS path to one or multiple database chunks. It supports wildcards %, * and ?.

tableName (optional) is a string indicating a table name.

diskUsage (optional) is a Boolean value indicating whether the result includes the column of diskUsage.

top (optional) is a positive number indicating the maximum number of chunks in the output. The default value is 1024. To remove the upper limit of chunks in the output, set top to -1.

Return metadata of specified tablet chunks on the local node. To get metadata about all tablet chunks of a distributed table, use getTabletsMeta together with pnodeRun.

Return a table with the following columns:

• chunkId: the unique identifier of chunk.

• path: the physical path of the partition.

• dfsPath: the dfs path of the partition.

• tableName: the table name.

• version: the version number.

• rowNum: the number of records in the partition.

• createCids: the Cids created when updating/deleting the table.

• latestPhysicalDir: the temporary physical directory storing the data generated by the operation with the latest Cid.

• diskUsage: the disk space occupied by partition (in Bytes).
