|---|---|---|---|---|---|---|---|---|---|---|---|
| id | uuid | 2147483647 | uuid_generate_v7() |
|
|
The record’s primary key. The definitive identifier of the record in the system. General Usage This column is system maintained and should be considered read only in normal operations. |
|||||
| instance_id | uuid | 2147483647 | null |
|
|
The database identifier of the Instance record for whom the Network Rule is being defined. |
|||||
| ordering | int4 | 10 | null |
|
|
Defines the order in which IP rules are applied. Lower values are applied prior to higher values. General Usage All records are ordered using unique ordering values within each Instance value. When a new Instance Network Rule is inserted with the ordering value of an existing Instance Network Rule record for the same Owner, the system will assume the new record should be “inserted before” the existing record. Therefore the existing record will be reordered behind the new record by incrementing the existing record’s ordering value by one. This reordering process happens recursively until there are no ordering value conflicts for any of an Instance’s Network Rule records. |
|||||
| functional_type | text | 2147483647 | null |
|
|
Indicates how the system will interpret the IP address rule. General Usage The valid functional types are:
|
|||||
| ip_host_or_network | inet | 2147483647 | √ | null |
|
|
An IPv4 or IPv6 IP address or network block expressed using standard CIDR notation. General Usage If this value is given you should not provide an IP host address range in the ip_host_range_lower/ip_host_range_upper columns. Providing range column values when this column is not null will result in a consistency check failure. |
||||
| ip_host_range_lower | inet | 2147483647 | √ | null |
|
|
An IPv4 or IPv6 IP host address which is the lower bound (inclusive) of a range of IP addresses. General Usage If the value in this column is not null a value must also be provided for the ip_host_range_upper column. Both ip_host_range_lower and ip_host_range_upper must be of the same IP family (IPv4 or IPv6). |
||||
| ip_host_range_upper | inet | 2147483647 | √ | null |
|
|
An IPv4 or IPv6 IP host address which is the upper bound (inclusive) of a range of IP addresses. General Usage If the value in this column is not null a value must also be provided for the ip_host_range_lower column. Both ip_host_range_lower and ip_host_range_upper must be of the same IP family (IPv4 or IPv6). |
||||
| diag_timestamp_created | timestamptz | 35,6 | now() |
|
|
The database server date/time when the transaction which created the record started. General Usage This column is system maintained and should be considered read only in normal operations. |
|||||
| diag_role_created | text | 2147483647 | √ | null |
|
|
The database role which created the record. General Usage This column is system maintained and should be considered read only in normal operations. |
||||
| diag_timestamp_modified | timestamptz | 35,6 | now() |
|
|
The database server date/time when the transaction which modified the record started. This field will be the same as diag_timestamp_created for inserted records. General Usage This column is system maintained and should be considered read only in normal operations. |
|||||
| diag_wallclock_modified | timestamptz | 35,6 | clock_timestamp() |
|
|
The database server date/time at the moment the record was actually modified. For long running transactions this time may be significantly later than the value of diag_timestamp_modified. General Usage This column is system maintained and should be considered read only in normal operations. |
|||||
| diag_role_modified | text | 2147483647 | √ | null |
|
|
The database role which modified the record. General Usage This column is system maintained and should be considered read only in normal operations. |
||||
| diag_row_version | int8 | 19 | 1 |
|
|
The current version of the row. The value here indicates how many actual data changes have been made to the row. If an update of the row leaves all data fields the same, disregarding the updates to the diag_* columns, the row version is not updated, nor are any updates made to the other diag_* columns other than diag_update_count. General Usage This column is system maintained and should be considered read only in normal operations. Direct Usage This column is frequently used by by application logic to resolve the “dirty write” issues which can arise from concurrent data changes. As such any administrative override of automatic system maintenance of this value should consider the ramifications on application function. |
|||||
| diag_update_count | int8 | 19 | 0 |
|
|
Records the number of times the record has been updated regardless as to if the update actually changed any data. In this way needless or redundant record updates can be found. This row starts at 0 and therefore may be the same as the diag_row_version - 1. General Usage This column is system maintained and should be considered read only in normal operations. |
