Hello
Our current application uses Cassandra to hold the chat items for user’s
conversation and a counter of unread chat messages (per each conversation).
We use TTL to delete old chat items, but we fail to see how we can define a
call back which will trigger an update (decrease) to the counters’
I have encountered the following piece of information regarding the use of
‘Counter Column’ in Cassandra: “If a write fails unexpectedly (timeout or
loss of connection to the coordinator node) the client will not know if the
operation has been performed. A retry can result in an over count” (- quot
Is it possible to fetch a column based on the row key and the column’s
timestamp only (not using the column’s name)?
