Splits a single LDIF file into multiple sets by separating entries below a specified base DN into different mutually-exclusive collections of entries. A number of algorithms are available to determine how entries should be split, and entries outside the split base DN may be included in all sets or added to a dedicated LDIF file.
Splits LDIF file 'whole.ldif' so that entries below 'ou=People,dc=example,dc=com' will be split into four sets, selected by computing a digest of the RDN component immediately below 'ou=People,dc=example,dc=com', with names starting with 'split.ldif'.

Splits LDIF file 'whole.ldif' so that entries below 'ou=People,dc=example,dc=com' will be split into four sets, selected by computing a digest of the first value of the 'uid' attribute, with names starting with 'split.ldif'.

Splits LDIF file 'whole.ldif' into four sets, with names starting with 'split.ldif', so that each entry immediately below 'ou=People,dc=example,dc=com' will be placed in the set that currently has the fewest entries.

Splits LDIF file 'whole.ldif' into four sets, with names starting with 'split.ldif', so that each entry immediately below 'ou=People,dc=example,dc=com' will be selected by matching that entry against a search filter. Entries matching '(timeZone=Eastern)' will go into the first set, entries matching '(timeZone=Central)' into the second set, '(timeZone=Mountain)' into the third set, and '(timeZone=Pacific)' into the fourth. Any entries not matching any of those filters will be placed by computing a hash on its RDN.

Splits the data by selecting the set with the fewest number of entries. When processing data in a flat DIT, this will essentially be a round-robin distribution. When processing data in a DIT with branches of varying sizes, this can help ensure that the resulting LDIF files will have roughly the same number of entries (although running the tool with multiple threads may make this less accurate). Unless the --assumeFlatDIT argument is provided, a cache will be used to ensure that subordinate entries are added into the same set as their parents.

--numSets {value}

--assumeFlatDIT
| Description | Indicates that the tool should assume that all entries below the split base DN will be exactly one level below that entry, so that it is not necessary to maintain a cache to determine where a subordinate entry's parent resides. If this argument is provided but one or more subordinate entries are found, then they will be added to a separate file so the appropriate set can be manually identified. |
Splits the data by using search filters to select the appropriate set. The filters will be evaluated in the order they were provided on the command line, and the entry will be added to the first set for which a matching filter is found. If the entry doesn't match any of the provided filters, then the appropriate set will be determined by computing a hash on the RDN. Unless the --assumeFlatDIT argument is provided, a cache will be used to ensure that subordinate entries are added into the same set as their parents.

--filter {filter}
| Description | A filter to evaluate against entries exactly one level below the split base DN to determine which set should be used to hold the entry. This argument should be provided multiple times, once for each set into which the data should be split, and the filters will be evaluated in the order they were provided on the command line until one is found that matches the target entry. |
| Required | Yes |
| Multi-Valued | No |
--assumeFlatDIT
| Description | Indicates that the tool should assume that all entries below the split base DN will be exactly one level below that entry, so that it is not necessary to maintain a cache to determine where a subordinate entry's parent resides. If this argument is provided but one or more subordinate entries are found, then they will be added to a separate file so the appropriate set can be manually identified. |
Splits the data by computing a hash on the value(s) of a specified attribute in entries immediately below the split base DN, and using a modulus operation to determine the set in which to place the entry. If an entry does not contain the target attribute, the set will be chosen based on a hash of the DN component immediately below the split base DN. Unless the --assumeFlatDIT argument is provided, a cache will be used to ensure that subordinate entries are added into the same set as their parents.
Splits LDIF file 'whole.ldif' so that entries below 'ou=People,dc=example,dc=com' will be split into four sets, selected by computing a digest of the first value of the 'uid' attribute, with names starting with 'split.ldif'.

--useAllValues
| Description | Indicates that the hashing process should examine all values for the target attribute. If this argument is not provided, then only the first value for the attribute will be used to determine the set in which an entry should be placed. |
--assumeFlatDIT
| Description | Indicates that the tool should assume that all entries below the split base DN will be exactly one level below that entry, so that it is not necessary to maintain a cache to determine where a subordinate entry's parent resides. If this argument is provided but one or more subordinate entries are found, then they will be added to a separate file so the appropriate set can be manually identified. |
Splits the data by computing a hash on the normalized representation of the DN component immediately below the split base DN, and using a modulus operation to determine the set in which to place the entry. This split algorithm does not require any caching to ensure that a subordinate entry is placed in the same set as its parent.
