Google provides a small amount of free usage of AppEngine. Beyond that,
you will need to set up billing.
If you had already submitted many rows (1000's) into ODK Aggregate, when
you set up publishing of all of that existing data and all future
(streaming) data into Fusion Tables, it is quite possible for the burst of
activity to publish that accumulated set of rows into Fusion Tables can
exceed your daily quota on AppEngine.
Note that there are different quota limits for different Google products
-- including Fusion Tables.
==================
Fusion tables does have some limitations on the quantity of data that can
be pumped into it from ODK Aggregate in a day. There is also a per-minute
limit, which ODK Aggregate automatically handles. For larger data sets,
there is also a overall size limit.
https://developers.google.com/fusiontables/docs/v1/using#KML
The default request quota limits are the following:
- 25,000 requests per day per API project, where reads count as one
request and writes count as five requests.
- 30 write requests per minute per table
You may request more quota at the Google APIs Console
https://code.google.com/apis/console under the "Quotas" tab.
The storage quota limits are:
- 250 MB per table
- 1 GB total among all your tables
============
There appear to be some limits w.r.t. the Google Maps integration within
Fusion Tables:
https://developers.google.com/fusiontables/docs/v1/using#Geo
Geographic design constraints
It's useful to keep in mind these limits:
- Only the first 350,000 rows of data in a table are mapped or
included in spatial query results.*
Therefore:
- Maps made with Fusion Tables Layers in the Google Maps API or
with the Fusion Tables web application will only show data from within this
first 350,000 rows. If you apply a filter to a table larger than 350K rows
and the filter matches data in rows after the first 350K, these rows will
not appear on the map.
- Queries with spatial predicates only return data from within this
first 350K rows. If you apply a SELECT query with a spatial predicate to a
very large table and the query matches data in rows after the first 350K,
these rows are not returned.
- When importing or inserting data, remember:
- The total size of the data sent in one API call cannot exceed 1MB.
- API calls to write data should not exceed 0.5 qps per table.
- A cell of data in Fusion Tables supports a maximum of 1 million
characters; it may sometimes be necessary to reduce the precision of
coordinates or simplify polygon or line descriptions.
- The maximum number of vertices supported per table is 5 million.*
- When looking at the map, you may notice:
- The ten largest-area components of a multi-geometry are shown.
- When zoomed far out, map tiles may exceed the 500
feature-per-tile limit, and features will be dropped from the map.*
- When zoomed farther out, tables with more than 500 features will
replace lines or polygons with dots.*

Thanks Mitch,
Greatly appreciate your reply.
I have been using the odk aggregate for data collection in offline mode
and downloading the data with odk briefcase.
And than manually uploading the csv and media to fusion table.
But few days back I set up the auth2 service account with odk aggregate
app engine to export the data to fusion table.
I got an error for regarding quota limit, even though the data was
manually uploaded and downloaded from fusion table.
- Is there any limit for fusion table export from odk agggregate server.
- And is there any limit for fusion table download/upload or maximum
number of records in fusion table
My project ID for cgsird2012.appspot.com is ID: cgsird2012 (
# 333502449148)
Please let me know the type of server setting for my data collection so
that in future quota limit will not occur.
Thanks & Regards
Neeraj

Hi Team,
I want to know the pricing for odk aggregate app engine.
- Our survey will capture nearly about 1 million data with 50 fields in
one form.
- The survey will take 90 days.
- Each submission will capture one image of size 200k
- We need the data to be exported to google fusion table.
- We need to access the fusion table frequently as to query the data
daily which could further be exportd as kml network link.
- Please let me know the pricing and storge requirements for read write
query.
Thanks
Neeraj
