Periklis Tsirakidis	cb337c3b71	Add LogQL AST walker (#3991) ... * Make expressions public scoped * Add walkable implementation * Use walkable in logql/optimize	5 years ago
Cyril Tovena	eff4ff1231	Improve matchers validations. (#3564) ... 1- It currently 500. 2- Happens too late, at ingester level and querier. (better at the frontend) 3- Improve API surface level, we don't need to expose this validation for anything else than ParseLogSelector. see #3216 Signed-off-by: Cyril Tovena <cyril.tovena@gmail.com>	5 years ago
Sandeep Sukhani	b152bc2cf3	check for stream selectors to have atleast one equality matcher (#3216) ... * check for stream selectors to have atleast one equality matcher * move equality matchers check to logql	5 years ago
Cyril Tovena	c971e8e65a	Optimizes SampleExpr to remove unnecessary line_format. (#3065) ... * Optimizes SampleExpr to remove unnessary line_format. When doing count_over_time and rate(), it doesn't make sense to have a line_format since you're counting line, you don't really care about what the line contains. At the same time this set the foundation of for further optimization, like parsing only required labels during label parsing. I've also found a bug where `topk by(foo) (1...` where not correctly parsed. Signed-off-by: Cyril Tovena <cyril.tovena@gmail.com> * For all range vector operations. Except for bytes one which count bytes in lines.
