Re: CQL 3.x Update ...USING TIMESTAMP...

@Tyler, Going back to your earlier proposal i.e. -- Instead, make the version part of the primary key: CREATE TABLE document_store (document_id bigint, version int, document text, PRIMARY KEY (document_id, version)) WITH CLUSTERING ORDER BY (version desc) --- My concern with this approach

Using DTCS, TTL but old SSTables not being removed

Running Cassandra 2.2.1 on 3 nodes (on EC2, from Datastax AMI, then upgraded). Inserting time-series data; All entries with TTL to expire 3 hours after the "actual_time" of the observation. Entries arrive with varied delay, and often in duplicate. Data is expiring (no longer visible from CQL),

cassandra-stress on 3.0 with column widths benchmark.

I’m trying to benchmark two scenarios… 10 columns with 150 bytes each vs 150 columns with 10 bytes each. The total row “size” would be 1500 bytes (ignoring overhead). Our app uses 150 columns so I’m trying to see if packing it into a JSON structure using one column would improve performance.
