      Our default configuration string literal for connection is getting too long, and it has almost reached the ISO C99 and C11 limits.

      Here are the top 5 config_entries:

      Entry Length Headroom to 4095
      wiredtiger_open_all 4042 53
      wiredtiger_open 4016 79
      wiredtiger_open_basecfg 3908 187
      wiredtiger_open_usercfg 3882 213
      WT_CONNECTION.reconfigure 2739 1356

       

      In fact, I can't compile my branch with a new config field anymore, because I get this:

      src/config/config_def.c:4110:5: error: string literal of length 4116 exceeds maximum length 4095 that ISO C99 compilers are required to support [-Werror,-Woverlength-strings]

      We need to solve this, but deprecating old fields is hard! We might need to break the config string into two or more smaller string literals.
