The Master ClientDataset loads and saves the data from and to a local file using MyBase. Until now, I do not have the intention to use InterBase. It will depend on the answer for the following question: I know that the clientdataset loads all the records from the local file to the memory. Is there any limitation on the maximum number of records that a clientdataset can retrieve or save to a local file ? Is the available memory the unique limitation ? Thank you for any answer. Marcelo.

For the file the limit is available disk space. Quote: Is the available memory the unique limitation ? I don't understand what you mean by "unique". Available memory is the limitation assuming you are using D2006 or later. -- Bill Todd (TeamB) Back to top Marcelo Colonna Rosman Guest Posted: Fri May 18, 2007 7:04 pm    Post subject: Re: How many records a ClientDataSet can get from a local fi Bill, Thak you for your answer. By "unique" limitation I want to mean that: 1) The clientdataset does not have any limitation on the number or records it can retrieve from the local file. 2) The maximum number of records that the clientdataset can retrieve from the file depends only on the available memory. On other words, only the available memory limits the maximum number of records the clientdataset can access and manipulate. Best regards, Marcelo.

AFAIK that is correct. Abstractly speaking - yes, it is. But after 10,000 records (or less) CDS is getting very slow one some of operations, like a inserting, deleting, updating.
