jdbc - How to import data into Apache Solr index from LDAP -

-

i have ldap-server contains large set of user data , import apache solr index. question not whether idea or not (as discussed here). need kind of architecture 1 of our production systems depends on solr index of our ldap data.

i'm considering different options so, i'm not sure 1 should preferred:

option 1: use apache solr dataimporthandler:

this seems straight forward solr way of doing so. unfortunately there not seem datasource available work ldap.

i tried combine jdbcdatasource jdbc-ldap-bridge. in theory might work driver looks quite dated (latest version 2007).

another option might write custom ldapdatasource using of ldap-libraries java (probably spring ldap, directly via jndi or similar?).

option 2: build custom feeder:

another option might write standalone service/script bridges between 2 services. feels bit reinventing wheel.

option 3: haven't thought of yet:

maybe there additional options here haven't discovered yet.

solved writing custom ldap datasource solr dataimporthandler.

it's not hard sounds. jdbcdatasource can used template writing custom datasource, have rewrite 1 java-class ldap protocol.

for accessing ldap-client there numerous options, such plain jndi, unboundid ldap sdk, apache ldap api, opendj ldap sdk or openldap jldap (there more had @ those).

i went unboundid ldap due documented api , full support ldapv3.

afterwards matter of referencing datasource data-config.xml.

a nice side-effect of setup is, can use goodies solr dataimporthandler provides while indexing ldap server (entity processors , transformers). makes easy map data structure between ldap , solr index.
