Developer's notes
Elasticsearch PHP client
[Elastica] was chosen as a PHP client because at the time development was started, it was the only one. 2 other clients are now available ([see list])
[Release v0.20.5.0] is used, compatible with Elasticsearch 0.20
Ugrading to Elasticsearch 0.90 would require [Release v0.90.1.0]
Plugin administration
- Elastic Search Types are table names (usr,interaction_instance,interaction_forum_post,view,group,artefact)
- Everytime the settings are saved, the mapping of each type is updated, and the triggers on each table are dropped and re-created. MySQL is not supported at the moment. The functions in ESindexing need to be updated for MySQL.
- Resetting a type inserts all the records of the related table into elasticsearch_queue.
- Indexing is done on cron tun.
Indexing
Every time a record is inserted, updated or deleted in one of the selected table, a DB trigger inserts the id and type of that record into elasticsearch_queue.
The original idea was creating more hooks on the different types, but it would be more time consuming and complicated.
