Constructor Detail

AdminVerifyDbRequest

public AdminVerifyDbRequest()

Constructs an AdminVerifyDbRequest object with default parameters.

AdminVerifyDbRequest

public AdminVerifyDbRequest(Map<String,String> options)

Constructs an AdminVerifyDbRequest object with the specified parameters.

Parameters:

options - Optional parameters.

• REBUILD_ON_ERROR: [DEPRECATED -- Use the Rebuild DB feature of GAdmin instead.]. Supported values:
  • TRUE
  • FALSE
  The default value is FALSE.
• VERIFY_NULLS: When TRUE, verifies that null values are set to zero. Supported values:
  • TRUE
  • FALSE
  The default value is FALSE.
• VERIFY_PERSIST: When TRUE, persistent objects will be compared against their state in memory and workers will be checked for orphaned table data in persist. To check for orphaned worker data, either set CONCURRENT_SAFE in options to TRUE or place the database offline. Supported values:
  • TRUE
  • FALSE
  The default value is FALSE.
• CONCURRENT_SAFE: When TRUE, allows this endpoint to be run safely with other concurrent database operations. Other operations may be slower while this is running. Supported values:
  • TRUE
  • FALSE
  The default value is TRUE.
• VERIFY_RANK0: If TRUE, compare rank0 table metadata against workers' metadata. Supported values:
  • TRUE
  • FALSE
  The default value is FALSE.
• DELETE_ORPHANED_TABLES: If TRUE, orphaned table directories found on workers for which there is no corresponding metadata will be deleted. Must set VERIFY_PERSIST in options to TRUE. It is recommended to run this while the database is offline OR set CONCURRENT_SAFE in options to TRUE. Supported values:
  • TRUE
  • FALSE
  The default value is FALSE.
• VERIFY_ORPHANED_TABLES_ONLY: If TRUE, only the presence of orphaned table directories will be checked, all persistence checks will be skipped. Supported values:
  • TRUE
  • FALSE
  The default value is FALSE.

The default value is an empty Map.
