No Fush of initial small expire tile list

[frodrigo]

I have trouble with imposm run for small updates.

As I understand the code the flush of the tiles list is done in two cases:

• on exist : https://github.com/omniscale/imposm3/blob/master/update/run.go#L93
• after at least 30s of update: https://github.com/omniscale/imposm3/blob/master/update/run.go#L128

So, for small update (>30s) the first flush will be done on next update.

My use case. I import a small extract of Andorra, 2 months old. Then use the run command, it update successfully the database quickly, in less than 30s. But no expire tile list is write to disk until I stop the command. I guess it will be written if I wait 24h for the next update, but not tested.

I had the same issue. What about adding a new configuration option to control this?

Fixed in #246.
