[GitHub] [couchdb-documentation] wlthomson opened a new issue #552: Replicator database configuration does not include max_history
wlthomson opened a new issue #552:
URL: https://github.com/apache/couchdb-documentation/issues/552
<!--- Provide a general summary of the issue in the Title above -->
CouchDB 3.1 replication seems to support `max_history` as a configurable parameter (see [couch_replicator_scheduler#L238](https://github.com/apache/couchdb/blob/4e64f5b492990b03f7f58a47ec173d048a3f381f/src/couch_replicator/src/couch_replicator_scheduler.erl#L238)).
## Expected Behavior
<!--- If you're describing a bug, tell us what should happen -->
<!--- If you're suggesting a change/improvement, tell us how it should work -->
`[replicator]max_history` to be added to `config/replicator.rst` as a configurable parameter for the replicator database (e.g. https://docs.couchdb.org/en/latest/config/replicator.html#replicator/max_history).
## Current Behavior
<!--- If describing a bug, tell us what happens instead of the expected behavior -->
<!--- If suggesting a change/improvement, explain the difference from current behavior -->
`[replicator]max_history` is not documented in `config/replicator.rst`.
## Possible Solution
<!--- Not obligatory, but suggest a fix/reason for the bug, -->
<!--- or ideas how to implement the addition or change -->
Add `max_history` to `config/replicator.rst`, including brief explanation and default value `20` (see [`couch_replicator_scheduler#L77`](https://github.com/apache/couchdb/blob/3.1.0/src/couch_replicator/src/couch_replicator_scheduler.erl#L77)).
## Steps to Reproduce (for bugs)
<!--- Provide a link to a live example, or an unambiguous set of steps to -->
<!--- reproduce this bug. Include code to reproduce, if relevant -->
N/A.
## Context
<!--- How has this issue affected you? What are you trying to accomplish? -->
<!--- Providing context helps us come up with a solution that is most useful in the real world -->
Experimenting with CouchDB in environments of low and/or intermittent connectivity, where it is important that replication restarts quickly when network connectivity is established. See https://github.com/apache/couchdb/issues/1399, which references configurable parameters `[replicator]retries_per_request` and `[replicator]max_history` as a potential solution to this problem.
## Your Environment
<!--- Include as many relevant details about the environment you experienced the bug in -->
* Version used: `v3.1.0`.
* Browser Name and version: Brave 1.8.95.
* Operating System and version (desktop or mobile): Ubuntu 20.04 LTS.
* Link to your project: https://github.com/wlthomson/ocsupply.

Apologies for the delay, just had a public holiday where I am, so was away from the desk for a few days :smiley:.
