ATG Search 10.1: configure incremental search indexing

I found strange behaviour for incremental search indexing process when incremental indexing works only without index deployment. To resolve this issue use configuration below. Actually this configuration been used to index ~2.5 millions products.

1. /atg/commerce/search/ProductCatalogOutputConfig/
incrementalUpdateSeconds=5 (BCC)

2. /atg/searchadmin/adapter/repository/SearchProjectIndexingOutputConfig/
enableIncrementalLoading=true (BCC)

3. /atg/search/routing/Configuration/
indexingReadTimeoutMs=900000 (SF1 & BCC)

4. /atg/search/routing/RoutingIndexService/
defaultActivePhysicalPartitions=6 (SF1 & BCC)

5. /atg/commerce/search/OrderOutputConfig/
incrementalUpdateSeconds=-1 (SF1 & BCC)

6. /atg/userprofiling/search/ProfileOutputConfig/
incrementalUpdateSeconds=-1 (SF1 & BCC)
