[tarantool-patches] [PATCH v2 3/5] box: introduce path field in key_part
Kirill Shcherbatov
kshcherbatov at tarantool.org
Wed Aug 15 15:15:01 MSK 2018
As we need to store user-defined JSON path in key_part
and key_part_def, we have introduced path and path_len
fields. JSON path is verified and transformed to canonical
form on index msgpack unpack.
Path string stored as a part of the key_def allocation:
+-------+---------+-------+---------+-------+-------+-------+
|key_def|key_part1| ... |key_partN| path1 | pathK | pathN |
+-------+---------+-------+---------+-------+-------+-------+
| ^
|-> path _________________|
Because of field names specified as format could be changed
key_part path persisted in Tarantool should be always started
with first-level field access via array index(not by name).
Part of #1012.
