The lucene indexes will be stored in memory instead of disk. This will be done by implementing a lucene Directory called RegionDirectory which uses Geode as a flat file system. This way we get all the benefits offered by Geode and we can achieve replication and shard-ing of the indexes. The lucene indexes will be co-located with the data region in case of HA.
A LuceneIndex object will be created for each index, to manage all the attributes related with the index, such as reflection fields, AEQ listener, RegionDirectory array, Search, etc.
