rafsun42 opened a new pull request, #1299:
URL: https://github.com/apache/age/pull/1299
* Explain command in the following format is supported now:
`EXPLAIN (VERBOSE, COSTS OFF, FORMAT XML) ...`
Note that, this is basically Postgres' EXPLAIN command, and the purpose of
this is to support debugging and regression tests.
* Add config param to switch transformation method of property filter
When the `age.enable_containment` parameter is on, the agtype containment
operator is used to transform property filter. When off, access operator is
used instead. The former case is preferable for GIN index, and the later for
BTREE expression index.
The idea of replacing containment with access operator in order to support
BTREE index is taken from a patch by Josh Innis.
A note on regression testing- although there are test cases for the
`age.enable_containment` parameter, sometimes it may be useful to set this
parameter before running any tests (not just the ones related to it). For
example, when the logic related to property transformation changes. It can be
set in the `age_regression.conf` file.
