Why is there a master and slave directory under /primo_indexes in 2-tier MFE topology
In 2-tier MFE topology there are 4 active search engines, the flow of the indexing /search process is as follows:
a. FE1 - includes: Master FE + Master SE
b. FE2 - includes: Slave FE + Slave SE
c. BE slot 1: BO + Master Agent
d. BE slot 2: Slave Agent
Each FE uses its own SE as a slice for searches.
? Master FE calls the Master agent to index, the index files are created in /primo_indexes Master directory.
? Before index is complete the files are copied to the /primo_indexes Slave directory.
? Master FE calls the Master agent to hotswap - the index is copied from the BO Master directory to the Master FE index folder,
? Master Agent initiates the Slave Agent to hotswap - the index is copied from the slot 2 directory to the Slave FE index folder,
