we use postgres. after setting log_statement=all, it'll log queries psql, not application accessing via jdbc. i find bit counter-intuitive. isn't ~95% of data access in application done via jdbc (or similar in other languages)? in articles hipaa implementation, it's recommemded set log_statement=all. purpose serve if majority of data access wouldn't logged @ all? what queries should log (or should log them @ all?) should use log4jdbc? or log_statement=all enough?

i've cloned small webapp onto client, next step me maven build war file can run it. i'm capable of installing maven , running command in executable block hoping on cleaner solution. the documentation maven cookbook isn't vast , can't seem find anywhere details how run maven build commands , using it. appears used more downloading dependencies rather building projects. any suggestions how might achieve without 'execute' block ? it's going execute resource or call shell_out @ point. build custom resource around make more resource-y @ heart maven install procedural step, not convergent step it's going bit awkward. if want background on procedural vs. convergent, wrote guide @ https://coderanger.net/thinking/ . that said, moving forward execute block fine. make sure consider idempotence rules, either notification or not_if / only_if guards.

roughly speaking need create 1 legend several subplots, have changing number of categories = legend entries . let me clarify bit deeper: i have figure 20 subplots, 1 each country within spatial scope: fig, ax = plt.subplots(nrows=4, ncols=5, sharex=true, sharey=false, figsize = (32,18)) within loop, logic group data need normal 2-dimensional pandas dataframe stats , plot each of these 20 axes: colors = stats.index.to_series().map(type_to_color()).tolist() stats.t.plot.bar(ax=ax[i,j], stacked=true, legend=false, color=colors) however, stats dataframe changing size loop loop, since not every category applies each of these countries (i.e. in 1 country there can 2 types, in there more 10). reason pre-defined specific color each type. far, creating 1 legend every subplot within loop: ax[i,j].legend(fontsize=9, loc='upper right') this works, blows subplots unnecessarily. how can plot 1 big legend above/below/beside these plots, since have defined according color....

i'm looking advantages of streaming on linking static files, eg images, pdf. to make question more clear, using node can stream files using fs.createreadstream i can understand streaming videos etc why should stream static files. can provide href? if static files available on url there's no need stream them using node. if node app wants return contents of static file hosted , served somewhere instead of streaming contents can return redirect file's url.
