Cassandra stores the version of the SSTable within the filename, following the format Keyspace-ColumnFamily-(optional tmp marker-)SSTableFormat-generation
Finding all sstables not matching version “ib”
find /var/lib/cassandra/data/ -type f | grep -v -- -ib- | grep -v "/snapshots"
The version numbers, to date are:
// b (0.7.0): added version to sstable filenames
// c (0.7.0): bloom filter component computes hashes over raw key bytes instead of strings
// d (0.7.0): row size in data component becomes a long instead of int
// e (0.7.0): stores undecorated keys in data and index components
// f (0.7.0): switched bloom filter implementations in data component
// g (0.8): tracks flushed-at context in metadata component
Version 1
// h (1.0): tracks max client timestamp in metadata component
// hb (1.0.3): records compression ration in metadata component
// hc (1.0.4): records partitioner in metadata component
// hd (1.0.10): includes row tombstones in maxtimestamp
// he (1.1.3): includes ancestors generation in metadata component
// hf (1.1.6): marker that replay position corresponds to 1.1.5+ millis-based id (see CASSANDRA-4782)
// ia (1.2.0): column indexes are promoted to the index file
// records estimated histogram of deletion times in tombstones
// bloom filter (keys and columns) upgraded to Murmur3
// ib (1.2.1): tracks min client timestamp in metadata component
// ic (1.2.5): omits per-row bloom filter of column names
Version 2
// ja (2.0.0): super columns are serialized as composites (note that there is no real format change,
// this is mostly a marker to know if we should expect super columns or not. We do need
// a major version bump however, because we should not allow streaming of super columns
// into this new format)
// tracks max local deletiontime in sstable metadata
// records bloom_filter_fp_chance in metadata component
// remove data size and column count from data file (CASSANDRA-4180)
// tracks max/min column values (according to comparator)
// jb (2.0.1): switch from crc32 to adler32 for compression checksums
// checksum the compressed data
