Red Gate have asked me to write a few articles for their Oracle site, so I’ve sent them a short series on “traditional” compression in Oracle – which means I won’t be mentioning Exadata hybrid columnar compression (HCC a.k.a. EHCC). There will be five articles, published at the rate of one per week starting Tuesday (15th Jan). I’ll be supplying links for them as they are published.
- Basic table compression
- Read-only data
- OLTP compression
- Basic index compression
- Costs of Index compression
Updated Aug 2015
Since I’ve got a little catalogue on compression started, I decided to add some items from my blog to the list, starting with a six-part series on HCC and compression units that I wrote (mostly) in the summer of 2012.
- Compression Units part 1
- Compression Units part 2
- Compression Units part 3
- Compression Units part 4
- Compression Units part 5
- Compression Units part 6
- Notes on advanced index compression
Miscellaneous
Advanced compression (2019): Oracle whitepaper for 19c

There’s a significant warning about basic compression in this comment on one of my notes about a bug with index compression and row dependencies.
