Mirza Aliev updated IGNITE-18954:
---------------------------------
Description:
{*}Motivation{*}:
We need to parse and be able to use filters, that user set for the distribution
zone
*Definition of done:*
* Filters are parsed and it is possible to filter arbitrary set of attributes
* Validator is implemented, so we can validate a string representation of a
filter expression
*Implementation details:*
Language must allow to perform simple operations, like
* “ “ – default empty filter, means that all nodes match
* () expressions with parentheses
* key1 = “A” && key2 = “B”, () && ()
* key1 = “A” || key2 = “B”, () || ()
* !=
Attributes representation must look like key -> value pairs, like
{noformat}
(region = EU || region = US) && (storage != HDD || storage = SSD)
{noformat}
