-------------------------------------
Labels: ise jdbc (was: )
> JDBC thin: support and optimize stream APIs for CLOBs
> -----------------------------------------------------
>
> Key: IGNITE-23239
> URL: https://issues.apache.org/jira/browse/IGNITE-23239
> Project: Ignite
> Issue Type: Task
> Reporter: Sergey Korotkov
> Priority: Major
> Labels: ise, jdbc
>
> Currently the stream-related APIs for CLOBs are not supported in JDBC drivers
> (both client and thin). Say the following ones:
> * Clob.setCharacterStream
> * Clob.setAsciiStream
> * PreparedStatement.setClob(int parameterIndex, Reader reader)
> * PreparedStatement.setCharacterStream
> * PreparedStatement.setAsciiStream
> *
> PreparedStatement.setUnicodeStream
> It makes the creation of CLOBs inefficient (memory wise) for large data.
> The whole data should be preloaded to RAM before the LOB creation.
> After that several copies of the input memory blocks are created just to pass
> it to prepared statement etc. It should be optimized to reduce the heap
> memory requirements.
