DHE | timburke: interesting... not what I expected... | 16:53 |
*** ediardo has joined #openstack-swift | 16:55 | |
timburke | the trouble is that sqlite doesn't know what kinds of values deleted might have -- as far as it's concerned, that could take any of 4 billion values, so it assumes the index wouldn't be useful | 16:55 |

DHE | depends on the index type. I'm used to mysql/pgsql which use btree indexes which are useful for searches on only 'a' when the index was built on (a,b) | 16:56 |
timburke | (really, it assumes it could take *any value* -- as i recall, it trusts the developer rather than impose a strict adherence to the schema) | 16:56 |
DHE | but for a hash index, yeah I can see that | 16:56 |
timburke | sqlite also uses btrees, as i recall. since it's a (deleted, name) index, you need to be searching off deleted as well as name to get the benefit | 16:57 |
DHE | ah, the commit message says "(name, deleted) index" so that's what confused me | 16:59 |
