Class CheckTableRequest

java.lang.Object

com.gpudb.protocol.CheckTableRequest

All Implemented Interfaces:

org.apache.avro.generic.GenericContainer, org.apache.avro.generic.IndexedRecord

public class CheckTableRequest
extends Object
implements org.apache.avro.generic.IndexedRecord

A set of parameters for GPUdb.checkTable.

Scans the requested tables as specified in tableNames for integrity. Any table chunks which fail the check will be marked as corrupt. By default the database will automatically repair corrupt tables (via truncating). Note that since this reads every table column from disk it may be a potentially long-running operation. The option LOCAL_ONLY can be used to skip any table files already written to a remote storage. Returns table corruption results.
