I have a column family with this conf: CREATE TABLE geoms ( geom_key text PRIMARY KEY, part_geom list<blob>, the_geom text ) WITH bloom_filter_fp_chance=0.010000 AND caching='KEYS_ONLY' AND comment='' AND dclocal_read_repair_chance=0.000000 AND gc_grace_seconds=864000 AND read_repair_chance=0.100000 AND replicate_on_write='true' AND populate_io_cache_on_flush='false' AND compaction={'class': 'SizeTieredCompactionStrategy'} AND compression={'sstable_compression': 'SnappyCompressor'};
I run this query "*select geom_key, the_geom, part_geom from geoms limit 1;*" in 700ms. When I run the same query without part_geom attr (*select geom_key, the_geom from geoms limit 1;)*, the query runs in 5 ms. *Is there a performance problem with a List<blob> attribute? * *Thanks in advance * -- Atenciosamente, Sávio S.
