Add versioned_update_old_row example

2018-12-07T19:02:26+00:00

A modification to the "turn UPDATE into INSERT" recipe that
also UPDATEs the previous row.  The example is using timestamps
to maintain a relationship between two objects.

Clarify init_scalar event use case

2018-09-06T14:44:55+00:00

Since I didn't even realize what this was for when reading the docs,
make it clearer that this is to mirror a Column default and remove
the extra verbiage about the mechanics of INSERTs.

Add Query.lazy_load_from attribute for sharding

2018-06-04T16:30:28+00:00

Added new attribute :attr:`.Query.lazy_loaded_from` which is populated
with an :class:`.InstanceState` that is using this :class:`.Query` in
order to lazy load a relationship.  The rationale for this is that
it serves as a hint for the horizontal sharding feature to use, such that
the identity token of the state can be used as the default identity token
to use for the query within id_chooser().

Also repaired an issue in the :meth:`.Result.with_post_criteria`
method added in I899808734458e25a023142c2c5bb37cbed869479
for :ticket:`4128` where the "unbake subquery loaders" version was calling
the post crtieria functions given the :class:`.Result` as the argument
rather than applying them to the :class:`.Query`.

Fixes: #4243

Update dogpile.cache example to be compatible with baked query.

2018-05-17T16:45:36+00:00

Updated the dogpile.caching example to include new structures that
accommodate for the "baked" query system, which is used by default within
lazy loaders and some eager relationship loaders. The dogpile.caching
"relationship_caching" and "advanced" examples were also broken due to
:ticket:`4256`.  The issue here is also worked-around by the fix in
:ticket:`4128`.

Note that this recipe requires
I3f86fcb12a6a9a89aa308b335e75c25969bcc30e in order for the
"advanced" example to work.
