I am thinking about nested transaction in Sqlite LSM extensions.

"There's a small sidenote (that I'm too lazy too find right now) in the select
docs that mentions that, in case of using min or max as aggregate, the
non-aggregate columns will come from the row that held the min/max value."
Look in
https://www.sqlite.org/quirks.html
under "6. Aggregate
Yes. See under item #3 in the Side note on https://sqlite.org/lang_select.html
Special processing occurs when the aggregate function is either min() or max().
Example:
SELECT a, b, max(c) FROM tab1 GROUP BY a;
When the min() or max() aggregate functions are used in an aggregate query,

Hi,
In past attempts at improving query performance these have
been added to encourage it to use an index that it can do a
SCAN thru' rather than the table that it would need to do a
SEARCH thru'.
SQLite is not using the PRIMARY INDEX to immediately locate the
appropriate row, but is

I can't solve your problem, but the PRIMARY KEY for "entrys" is

I am unable to reproduce the problem here. Can you run it under

We have found a use-after-free problem in the test harness.

Hi,
ORDER BY "key" DESC
This should be ASC, not DESC: I've been working on versions of the query

Hi,
I'm trying to implement a "streaming" version of the classic "select the
latest version of a record" query.
By "streaming" I mean a query that executes by streaming what it needs out
of tables and indexes as it needs it rather than using temporary b-trees or
materializing anything up
