The Lexico Distribution Partition defines a partition for a lexicographic distribution algorithm.
A lexicographic distribution algorithm is based on a partitioning key (named the distribution attribute) and a set of lexicographic partitions. A lexicographic partition is defined by a lower boundary and an upper boundary. When a distribution attribute value is inside the range of the lexicographic partition then the target entry is a member of the partition. For example, if the distribution attribute is 'sn' and if one lexicographic partition boundary is ["A"-"E"], then the entry containing "sn=BOB" is a member of that partition, while the entry containing "cn=PAT" is not.
The Lexico Distribution Partition component inherits from the Distribution Partition
A description of each property follows.
| Basic Properties: | Advanced Properties: |
|---|---|
| ↓ lower-bound | ↓ criticality |
| ↓ partition-id | |
| ↓ upper-bound | |
| ↓ workflow-element |
| Description | The lower boundary of the partition. The lower boundary of the partition is a string. This boundary can be as small as a single character or it can be larger. Both values "A" and "BEGIN" are valid boundary values. Use the keyword 'unlimited' if the lower boundary is not limited. |
|---|---|
| Default Value | None |
| Allowed Values | A String |
| Multi-valued | No |
| Required | Yes |
| Admin Action Required | None |
| Advanced Property | No |
| Read-only | Yes |
| Description | Identifies the partition. The partition identifier is unique for a given data partition. The identifier is an integer. |
|---|---|
| Default Value | None |
| Allowed Values | An integer value. Lower value is 0. |
| Multi-valued | No |
| Required | Yes |
| Admin Action Required | None |
| Advanced Property | No |
| Read-only | Yes |
| Description | The upper boundary of the partition. The upper boundary of the partition is a string. This boundary can be as small as a single character or it can be larger. Both values "Z" and "END" are valid boundary values. Use the keyword 'unlimited' if the upper boundary is not limited. |
|---|---|
| Default Value | None |
| Allowed Values | A String |
| Multi-valued | No |
| Required | Yes |
| Admin Action Required | None |
| Advanced Property | No |
| Read-only | Yes |
| Description | The workflow element which contains the partition. |
|---|---|
| Default Value | None |
| Allowed Values | The DN of any Workflow Element. |
| Multi-valued | No |
| Required | Yes |
| Admin Action Required | None |
| Advanced Property | No |
| Read-only | Yes |
| Description | The criticality determines whether a partition must be up, or if it is acceptable to have it down during search operations. This parameter is meaningful only for search requests. If the partition's workflow element is fully saturated, the behavior is based on the criticality parameter: - TRUE: the partition is critical, the search operation is stopped and an UNAVAILABLE result code is returned to the client. - PARTIAL: the partition is partially critical, the search operation continues with other partitions involved in the search. The entries which are retrieved from healthy partitions are returned to the client. A result code of ADMIN_LIMIT_EXCEEDED is returned to the client, which indicates that the entries returned may be incomplete because one or more partitions are fully saturated. - FALSE: the partition is not critical, the search operation continues with other partitions involved in the search. The entries which are retrieved from healthy partitions are returned to the client. No special result code is returned to the client. |
|---|---|
| Default Value | true |
| Allowed Values | false - The partition is not critical. partial - The partition is partially critical. true - The partition is critical. |
| Multi-valued | No |
| Required | No |
| Admin Action Required | None |
| Advanced Property | Yes |
| Read-only | No |
