Indexing into SOLR is controlled by an indexing daemon: aidxd. This daemon probes PostgreSQL for available load-id(s) to index. This "queue" is represented by the table reporting.t_client_index_process. See Data Warehouse Design for more information on the structure of this table. When processing is successfully completed into PostgreSQL, apgupd registers a new, index-ready load-id. The indexing daemon aidxd recognizes this as an available load-id and begins the indexing process for that particular load-id.
Usage

|---|---|---|

aidxd [ Options ... ]
--nodaemon don't put process into background
--once only process one load-id
--pidfile=s specify location of PIDFILE
(default=/var/log/alexandria/aidxd.pid)
--interval=i n-seconds between probing for new loads
--tmp=dir specify temporary file storage (default=/tmp)
--clean remove temporary processing directory
--batchsize=i maximum number of documents to parallelize
--nthreads=i maximum number of processes to parallelize
--facility=s logging facility (default=aidxd)
--help print this usage and exit
--------
--idxversion= 21
--idxcls=s Alexandria::DWH::Index::DocumentEx
--idxexe=s specify indexing script (default aidx)
--quiet suppress output from sub-process
NOTE: suppressing this output will make it difficult
to track down errors originating in --idxexe
--solrdbname=s base url for index (default=alexandria)
--core=s index core (default=alexandria)
--autooptimize issue an 'optimize' call to SOLR after optinterval
continuous load-id(s)
--optinterval # of load-id(s) after which an optimize is issued
(default=100)
--optsegments=n optimize down to n-segments (default=16)
--nostatistics do not gather indexing statistics |
