René Rössler updated COUCHDB-1895:
----------------------------------
Description:
I have a database with ~5000 documents and a update sequence of ~100,000.
If I start a filtered, continuous changes stream with heartbeat set to 1000, I
get the first heartbeat after ~1 seconds.
If I start the same changes stream with a heartbeat of 10,000, I get the first
heartbeat after ~10 seconds.
But if I start the same changes stream with a heartbeat of 10,000, I get the
first heartbeat after ~57 seconds and the second heartbeat ~2 seconds later.
Getting all the changes without a continuous feed takes about 15 seconds.
I measured the timings with this command:
bq. date && wget --quiet
"http://localhost:5984/database/_changes?filter=design/filter&feed=continuous&heartbeat=30000&since=0";
-O /dev/stdout |perl timing.pl
{code:title=timing.pl|borderStyle=solid}
#!/usr/bin/perl
use POSIX qw(strftime);
while(!eof(STDIN))
{
$line=<STDIN>;
print strftime("%F %T", localtime), $line;
}
{code}
Couchdb is version 1.4.0 installed via homebrew on Mac OS 10.8.5.
