SYSTEM$GET_DIRECTORY_TABLE_STATUS¶

Returns a list of records that contain the directory table consistency status for stages in your account. Consistency status indicates whether a directory table on a replicated stage has information about (is consistent with) all of the replicated files on the stage.

Stage, pipe, and load history replication , Directory tables

Syntax¶

SYSTEM$GET_DIRECTORY_TABLE_STATUS( [ '<stage_name>' ] )
Copy

Arguments¶

Optional:

'stage_name'

Stage for which you want to retrieve the directory table consistency status. When you specify a stage name, the function returns a list with a single record for the directory table on that stage.

Returns¶

Returns a list of directory table consistency records for each stage in your account. The list contains a maximum of 10,000 records. If you specify a 'stage_name' argument, the function returns a list with a single record for the directory table on that stage.

The records are in JSON format and contain the following name/value pairs:

{
  "stage" : "STAGE1",
  "status" : "INCONSISTENT"
}

Where:

stage

The stage on which the directory table is enabled.

status

Consistency status for the directory table. CONSISTENT if the directory table is fully consistent with the replicated content on the stage; INCONSISTENT otherwise. A status of INCONSISTENT means that Snowflake cannot verify consistency, and that the directory table might be missing information about some files that exist on the stage.

Usage notes¶

  • To call this function, you must use a role that is granted or inherits the READ privilege on the stage(s) for which you want to retrieve consistency status.

  • To update the consistency status from INCONSISTENT to CONSISTENT, perform a full refresh using the ALTER STAGE … REFRESH command.

Examples¶

The following example retrieves a list of consistency status records for the stages in the account:

SELECT SYSTEM$GET_DIRECTORY_TABLE_STATUS();
Copy

Output:

[
  {
    "stage" : "STAGE1",
    "status" : "CONSISTENT"
  },
  {
    "stage" : "STAGE2",
    "status" : "INCONSISTENT"
  }
]

The following example retrieves a consistency status record for a stage named stage1:

SELECT SYSTEM$GET_DIRECTORY_TABLE_STATUS('stage1');
Copy

Output:

[
  {
    "stage" : "STAGE1",
    "status" : "CONSISTENT"
  }
]
