<p class="MsoNormal">Hi everyone,<o:p></o:p></p>
<p class="MsoNormal">I have a multi-master architecture of postgres databases with a central one (HQ) and several distributed around the globe (field offices).<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Each of the field office’s databases has limited availability of a network connection, and can (and should) work only on a small portion of data, related to that field’s activity.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Every table in my datamodel containing data related to field offices has a column (eg. “field_id”) that allows data segregation.<o:p></o:p></p>
<p class="MsoNormal">What I’m looking for is a way to filter data using this “field_id” to sync with every office only data from the HQ database related to that office.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Previously there was a feature called “custom select” <a href="https://bucardo.org/Bucardo/customselect/">
https://bucardo.org/Bucardo/customselect/</a> but it seems to be deprecated.<o:p></o:p></p>
<p class="MsoNormal">Is that true?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">If true, there is another way to satisfy this requirement?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">PS: please note that this sync is multi-master, so data can be inserted/deleted/updated locally (in the field offices) and then they must come back to the central db.<o:p></o:p></p>
<p class="MsoNormal">There should be no conflicts because every office works on a different subset.<o:p></o:p></p>
<p class="MsoNormal">Of course when I sync back data to HQ I don’t need any filter.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Thanks in adavance, any help or suggestion would be very much appreciated!<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
