Description
We are developing our own repository extension for storing spring session. In the spring codebase there are two PRINCIPAL_NAME_INDEX_NAME constants, one being the FindByIndexNameSessionRepository.PRINCIPAL_NAME_INDEX_NAME and the other is ReactiveFindByIndexNameSessionRepository.PRINCIPAL_NAME_INDEX_NAME. In all the spring session repository implementations FindByIndexNameSessionRepository.PRINCIPAL_NAME_INDEX_NAME is used to extract the principal. What is the use of ReactiveFindByIndexNameSessionRepository.PRINCIPAL_NAME_INDEX_NAME ?
