Free Write and Read Operations

[José Luis Ordiales Fernandez]

Hi,

im a student of Spain and im using the free version of the GAE. Actually im working with a CSV file and I get to import to the Datastore, but this CSV file has about 200 columns and 1000 rows and when i try to read the data into the datastore the GAE tell me that i have exceed the number of reads.

I have seen that if you enable your billing the cost of reading each 100k operations is 0.07$,but i dont know how many operations of read has my CSV file.

Can anyone help me?

Thanks in advance.

Every field have index by default.

You can calc write ops by table

If you're lazy, you can also try importing it on the local dev server,
then goto the local datastore viewer. It will tell you how many write
ops each entity required.

You can also disable unneeded indexes (what Timofey is talking about),
which will reduce cost and improve performance.

I do some tool which list all tables and shows bottlenecks base on:
https://code.google.com/intl/en/appengine/docs/billing.html.

First of all do indexed=False for all fields! - not sure about
overhead of import tools since could generate more operation than is
need.
