Zendesk Maxwell crashing/going down - mariadb
We have maxwell running on docker in our production and it is configured to listen to changes on MariadDb tables and push them to a kafka topic. Our MariadDb has some 10-12 tables and we have configured maxwell to listen to only 4 tables and all these 4 tables are heavily used (number of writes is too high).
Recently we have seen that our Maxwell is going down, following are the few error logs we found when maxwell is going down
Oct 28, 2022 # 06:10:40.037 06:10:40,037 ERROR MysqlParserListener - (parse SET STATEMENT max_statement_time = 60 FOR flush table)
Oct 28, 2022 # 06:10:40.040 06:10:40,040 ERROR SchemaChange - Error parsing SQL: 'SET STATEMENT max_statement_time=60 FOR flush table'

As the last error log says Error on bin log position Position[BinlogPosition[mysql-bin-changelog.049610:3209], so to verify whether bin log file with name mysql-bin-changelog.049610:3209 exists or not we ran SHOW binary logs; and we found that file in list outputted by above command
Please help me in understanding what is going wrong here and help in solving the issue

The java backtrace shows this is an error in Maxwell. This was reported as issue 1931.
The issue is that Maxwell in the v1.37.7 doesn't parse SET STATEMENT ... FOR against a blacklist of SQL like FLUSH that its meant to take no action on.
Due to a very responsive upstream, this is is now fixed in v1.39.2.

How can I create a CASE Statement BETWEEN Two Dates?
I am looking to do a CASE statement in a calculated field to identify dates as holidays, and have tried:
CASE
WHEN
FORMAT_DATETIME("%Y%M%D", date) BETWEEN 20190218 AND 20190219 OR
FORMAT_DATETIME("%Y%M%D", date) BETWEEN 20220220 AND 20220222
THEN 'presidents_day'
ELSE NULL
END
I am having trouble formatting the date correctly to use the BETWEEN statement and I am getting the error:
Invalid formula - Operator "BETWEEN" doesn't support TEXT BETWEEN NUMBER AND NUMBER. Operator "BETWEEN" supports ANY BETWEEN ANY AND ANY.
Data Set (Google Sheets):
date
17 Feb 2019
18 Feb 2019
19 Feb 2019
20 Feb 2019
19 Feb 2022
20 Feb 2022
21 Feb 2022
22 Feb 2022
23 Feb 2022
Expected output:
date
Date_CASE
Feb 17, 2019
Feb 18, 2019
presidents_day
Feb 19, 2019
presidents_day
Feb 20, 2019
Feb 19, 2022
Feb 20, 2022
presidents_day
Feb 21, 2022
presidents_day
Feb 22, 2022
presidents_day
Feb 23, 2022
Google Data Studio report
Using the BETWEEN operator in conjunction with the DATE function ("Creates a date" in the YYYY, MM, DD format) would create the required CASE statement (where date represents the date field):
CASE
WHEN
date BETWEEN DATE(2019, 02, 18) AND DATE(2019, 02, 19) OR
date BETWEEN DATE(2022, 02, 20) AND DATE(2022, 02, 22)
THEN "presidents_day"
ELSE NULL
END

Issues with ARIMAX forecasting (auto.arima)
I'm trying to forecast an accumulated monthly time series (see data below) with the auto.arima function with exogenous regressors. I have two issues. 1) My first issue is that when I fit the model and use the forecast function to predict the second half of 2019 the forecast starts from zero as can be seen in this forecast plot. This only happens when I include a matrix of exogenous regressors and not when I use a single time series as regressor as can be seen in this plot. Why is that? My code is: regnskab <- ts(data$Regnskab, frequency = 12, start = c(2014,1), end = c(2019,6)) budget <- ts(data$Budget, frequency = 12, start = c(2014,1), end = c(2019,6)) dagtilbud <- ts(data$Dagtilbud, frequency = 12, start = c(2014,1), end = c(2019,6)) skole <- ts(data$Skole, frequency = 12, start = c(2014,1), end = c(2019,6)) sundhed <- ts(data$Sundhed, frequency = 12, start = c(2014,1), end = c(2019,6)) miljø <- ts(data$Miljø, frequency = 12, start = c(2014,1), end = c(2019,6)) tsmatrix <- cbind(budget, dagtilbud, miljø, skole, sundhed) fit <- auto.arima(regnskab, xreg = tsmatrix) fcast <- forecast(fit, h = 6, xreg = tsmatrix) autoplot(fcast) summary(fcast) 2) My second issue is that I want a forecast for 6 months forward, but the h=6 option does not apply when including exogenous regressors. Can this be solved in any way? Again, it is not a problem without exogenous regressors. I hope you can help and sorry for the data spamming!

The xreg matrix in the forecast function should be for the future time periods. If you want h=6, then give a matrix of 6 rows corresponding to those 6 periods.
rrule to get the 2nd Monday, Wednesday and Friday of the month, for every month
I am trying to create a rrule for my fullcalendar event, that occur on the 2nd Monday, Wednesday and Friday of the month for every month.
Here is the rrule I have tried
RRULE:FREQ=MONTHLY;COUNT=10;INTERVAL=1;WKST=SU;BYDAY=MO,WE,FR;BYSETPOS=2
events: [{
title: 'rrule event',
rrule: {
freq: RRule.MONTHLY,
count: 10,
interval: 1,
wkst: RRule.SU,
byweekday: [RRule.MO, RRule.WE, RRule.FR],
bysetpos: [2]
},
duration: '02:00',
rendering: 'inverse-background'
}
],
This is what I get

9 Fri, 03 Jan 2020 12:33:53 GMT
10 Wed, 05 Feb 2020 12:33:53 GMT
What is expected is
1 Mon, 08 Apr 2019
2 Wed, 10 Apr 2019

RFC 5545, section 3.3.10. states: Each BYDAY value can also be preceded by a positive (+n) or negative (-n) integer. If present, this indicates the nth occurrence of a specific day within the MONTHLY or YEARLY "RRULE". So the rule you're looking for literally specifies the 2nd Monday (2MO), Wednesday (2WE) and Friday (2FR) of each month. FREQ=MONTHLY;COUNT=10;BYDAY=2MO,2WE,2FR (click to see the results) Note that INTERVAL=1 is the default and WKST=SU is meaningless in this case, so you can just as well omit them. Btw, your rule basically says, of all Mondays, Wednesdays and Fridays of a month, take the second instance in that month.
