On 19.04 under gnome, baloo creates a 64GB index, takes half my 16GB memory and 25% CPU.
After uninstalling baloo following
baloo_file_extractor in Ubuntu 18.04 LTS taking up a lot of memory
the problem goes away.
I still would like to understand:
baloo, by installing dolphin maybe?baloo do for me when running gnome?
I simulated the installation of Dolphin on Ubuntu 19.04 using apt install -s dolphin. I then searched the output for packages containing "baloo":
dkb: ~/Desktop $ grep -i baloo baloo.txt
The output:
Inst libkf5balooengine5 (5.56.0-0ubuntu1 Ubuntu:19.04/disco [amd64])
Inst libkf5baloo5 (5.56.0-0ubuntu1 Ubuntu:19.04/disco [amd64])
Inst baloo-kf5 (5.56.0-0ubuntu1 Ubuntu:19.04/disco [amd64])
Inst libkf5baloowidgets-data (4:18.12.3-0ubuntu1 Ubuntu:19.04/disco [all])
Inst libkf5baloowidgets5 (4:18.12.3-0ubuntu1 Ubuntu:19.04/disco [amd64])
Inst libkf5baloowidgets-bin (4:18.12.3-0ubuntu1 Ubuntu:19.04/disco [amd64])
Installing Dolphin on Ubuntu 19.04 would pull in 100+ packages including the ones listed above. (The last package wouldn't be pulled in if I used --no-install-recommends.) It's fairly safe to conclude that installing Dolphin on your system with or without recommends pulled in baloo.
To verify that baloo is indeed installed when Dolphin is installed, I ran sudo apt install dolphin in a virtual machine of Ubuntu 19.04.
0 upgraded, 181 newly installed, 0 to remove and 0 not upgraded.
Need to get 41.2 MB of archives.
After this operation, 206 MB of additional disk space will be used.
I went ahead and after the installation was complete but without running Dolphin, I ran pgrep -a baloo and got back the prompt. In other words, baloo wasn't running.
I rebooted and ran pgrep -a baloo again but without running Dolphin:
dkb: ~ $ pgrep -a baloo
1672 baloo_file
dkb: ~ $
Top didn't show any unusual activity probably because there wasn't much for baloo to index. And that is reflected in the size of the index file:
dkb: ~/.local/share/baloo $ ls -al
total 516
drwxrwxr-x 2 dkb dkb 4096 Jun 28 18:05 .
drwx------ 23 dkb dkb 4096 Jun 28 18:11 ..
-rw-rw-r-- 1 dkb dkb 516096 Jun 28 18:05 index
-rw-rw-r-- 1 dkb dkb 8192 Jun 28 18:06 index-lock
dkb: ~/.local/share/baloo $
I then launched Dolphin (while keeping a terminal window with top running). Again, because there was very little to index, top didn't show any unusual activity and pgrep -a baloo gave the same output as I got after the reboot.
I still would like to understand
How did I got baloo'd, by installing dolphin maybe? What does baloo do for me when running gnome?
The screenshot has top running on the side.
So, you can use the Dolphin-baloo combination even in a GNOME session. However, by default
* I don't know your reason for installing Dolphin on Ubuntu and so can't comment further. If you are interested in keeping Dolphin but don't want baloo active, run
balooctl status
On my Kubuntu, it shows me
04:27 PM ~/Desktop $ balooctl status
Baloo File Indexer is running
Indexer state: Idle
Indexed 2323 / 2323 files
Current size of index is 193.11 MiB
06:53 PM ~/Desktop $
Then, run
balooctl disable
Doing so disables the file indexer. And the disabled state survives a reboot on Ubuntu 19.04 (GNOME):
dkb: ~ $ balooctl status
Baloo is currently disabled. To enable, please run balooctl enable
dkb: ~ $

***: I think baloo ignores dot files and dot folders in the version present in Kubuntu 18.04 and so excluding dot files may have been unnecessary!
Your questions:
How did I get baloo, by installing dolphin maybe?
aptitude why shows the causes for packages to be installed (install it with sudo apt-get install aptitude if you don't have it).
For instance, I had the same inquiry as you, and I ran
$ dpkg -l | grep baloo
ii baloo-kf5 5.68.0-0ubuntu1 amd64 framework for searching and managing metadata
ii libkf5baloo5 5.68.0-0ubuntu1 amd64 framework for searching and managing metadata core lib.
ii libkf5balooengine5 5.68.0-0ubuntu1 amd64 framework for searching and managing metadata plugins
ii libkf5baloowidgets-bin 4:19.12.3-0ubuntu1 amd64 Wigets for use with Baloo - binaries
ii libkf5baloowidgets-data 4:19.12.3-0ubuntu1 all Wigets for use with Baloo - data files
ii libkf5baloowidgets5:amd64 4:19.12.3-0ubuntu1 amd64 Wigets for use with Baloo
to tell the name of the packages, and then
$ aptitude why baloo-kf5
i dolphin-plugins Depends dolphin
i A dolphin Depends baloo-kf5
$ aptitude why libkf5baloo5
i dolphin-plugins Depends dolphin
i A dolphin Depends libkf5baloo5 (>= 5.3.0+git20150512)
$ aptitude why libkf5balooengine5
i dolphin-plugins Depends dolphin
i A dolphin Depends libkf5baloo5 (>= 5.3.0+git20150512)
i A libkf5baloo5 Depends libkf5balooengine5
to tell the chain of dependencies leading to the installation of some of the baloo-related packages (just for the sake of illustration, the first aptitude command already shows that dolphin required baloo).
The information shown in the output of the last command should be read:
"dolphin-plugins was installed manually.
dolphin-plugins required dolphin, which was installed automatically then.
dolphin required libkf5baloo5, which was installed automatically then.
libkf5baloo5 required libkf5balooengine5, which was installed automatically then.
libkf5balooengine5 did not require any other package to be installed automatically."
What does baloo do for me when running gnome? I split this in two parts.
baloo do...? Generally speaking, baloo indexes files for later fast searching.mlocate?
mlocate indexes file names only.
baloo can index file contents, so that searching returns "better" results (depending on the way you configure baloo).
Of course, baloo can be configured to index only file names (see locate vs. baloo and answer there), for instance in the interest of storage space, in which case it is similar to mlocate.baloo?
As expected, dolphin makes use of baloo to search for files, either names or contents, in its searches (which you can pull with either the magnifying glass at the top right or the "Search for" list in the side bar). This is regardless of you using Gnome or other session manager.In addition, Gnome (and here I am answering specifically to your mention of it) has its Activities search bar, which is a more complex search tool. Without going into much detail, this Gnome search is fed by Search providers. A few such providers are setup with the initial installation, but you can add others, so that the search results include those as well. In principle, I guessed baloo could be a search provider as well.
So far, I could not find information on how to do that.
As of 02/11/20, following an upgade from 18.04 to 20.04, the baloo syslog problem occurred (first time ever). The file /var/log/syslog exploded in size.
To be absolutely clear about this. Running
balooctl disable
did not stop the problem. I removed baloo using
sudo apt-get remove baloo-kf5
I then cropped the syslog files using
sudo sh -c 'cat /dev/null > /var/log/syslog'
syslog had reached ~40GB, syslog.1 was 48GB
This code is malicious. I subsequently just discovered that baloo stores an index under
.local/share/baloo/index
This was also 48GB. Something urgently needs to be done about baloo. Reading through all the various posts on forums out there, this issue has been a recurring problem, with no "good" solution, since at least 2014. Evidently, as my experience shows, it remains a problem today.
upon following the answers given above i still found baloo running and eating up a ton of resources. to summarize what, at this point, seems to have finally buried this unholiest of demons:
I disabled the indexer:
balooctl disable
I removed the package baloo-kf5, but I still found baloo processes running and spawning, so I ended up doing:
sudo apt remove baloo-kf5 libkf5baloo5 libkf5balooengine5
After that, I checked to see if, for whatever reason, baloo was still present with top... and it was...
~/.local/shared/baloo for its bloat.Perhaps sudo apt purge would have been a better idea, but whatever...
What nonsense, I'm annoyed...
if a baloo process spawns, I'm lighting my box on fire...
