    Hi guys, I have a strange issue with writing data. I have a table in which i have to write regex pattern strings as data. But both ILP and csv import are ignoring the named capture groups. for example, if i have a pattern like "(?P<capture_group_name>\S+)" both ILP and csv tends to strip off everything within and including the angle brackets which in turn writes data as "(?P\S+)". I did not try out postgres wire protocol yet. Another issue is that when there is a predefined table and try to write data using ILP (using the python client) no data is written and the server logs error as "could not parse measurement, NONE at 700, line (may be mangled due to partial parsing)". when allowed to create table dynamically, 54 entries have been written to db and then the server exited with the same error message as before, but with a different line number. CSV import was able to write all the 80 rows to db. All these for the same input data. In all these scenarios the regex capture group names are ignored and not sure why... Looking for some help to understand what is going on. Thanks!

    Hi Team, I'm running questdb on my local machine (win10) and after starting it up either as a service or exe, the JAVA.EXE takes 3,7GB private memory! (If I run it with an initial DB, java.exe consumes only few hundred MB.) Are there any settings for memory management to restrict usage? Thanks, Tibor

    Hi, I just noticed that QDB crashes when I run "select first(0.0)" - I guess this is because group by functions currently don't work together with constants?

    And maybe yet another question - Can anyone think of a simple solution how to solve this with QDB: Given an aggregation over time , find the max value for a column as well as the timestamp assigned to this max value? E.g. in my use case weather data, I want to find the date in which the maximum temperature was reached for each year
