when we are creating the ztable for that in technical settings

one option is there synchronization of buffer creation

mainly it comes under the performence issues

Hello,

For table bufferring u can select the buffering type and all from the Technical Settings at the time of ZTable creation.

Advantages and disadvantages of this method of buffer synchronization:

> Advantage: The load on the network is kept to a minimum. If the buffers

were to be synchronized immediately after each modification, each server

would have to inform all other servers about each modification to a buffered

table via the network. This would have a negative effect on the performance.

> Disadvantage: The local buffers of the application servers can contain

obsolete data between the moments of synchronization.

This means that:

> Only those tables that are written very infrequently (read mostly) or for

which such temporary inconsistencies are of no importance may be buffered.

> Tables whose entries change frequently should not be buffered. Otherwise

there would be a constant invalidation and reload, which would have a

negative effect on the performance.

> An index helps you to speed up read accesses to a table. An index can be

considered a sorted copy of the table that is reduced to the index fields.

The table buffers reside locally on the application servers.

Buffering can substantially increase the performance when the records of the table

are accessed. Choosing the correct buffering type is important.

The table buffers are adjusted to changes to the table entries at fixed intervals.

The more frequently a table is read and the less frequently the table contents are

changed, the better it is to buffer the table.
