Collections (MAP) data in Column Family
We are running Apache Cassandra 2.1.9. In one of our Column Family, we have MAP type column. We are seeing unusual data size of the column family (SSTables) with few 1000's of rows, while debugging, I looked at one of the SSTable and I see some unusual data in it
Below is JSON of one Row Key data
1. There is usual Column name, Key-Value pair and TS for the MAP - all_products column name 2. After Key Value pair, I see Cluster Column style data in MAP with a "t" marker in between, this is literally repeated millions of cells - all_products:_","all_products:!",1442797965371999,"t",1442797965
Any clues on what is happening here? I know "d" marker for marked for delete, "e" marker for TTL but dont know what "t" marker is for?
