[BP MB-34193] - Set read deadline to connections between memcached and projector data path

    XMLWordPrintable

Details

    Description

      In one of the customer issues, it was observed that TCP closed the connection on Memcached but projector did not receive any notification. Because of this, connection of projector was kept open and projector was waiting for data while memcached stopped sending the data.

      While the actual issue is external to couchbase product, it is good to have a read-deadline on memcached to projector data paths to safeguard from extreme scenarios like missing TCP notifications
