----------------------------------------
Summary: JDBC thin: support and optimize stream APIs for CLOBs and
BLOBs
Key: IGNITE-23114
URL: https://issues.apache.org/jira/browse/IGNITE-23114
Project: Ignite
Issue Type: Task
Reporter: Sergey Korotkov
Currently the stream-related APIs for CLOBs and BLOBs are not supported in JDBC
drivers (both client and thin). Say the following ones:
* Blob.setBinaryStream
* PreparedStatement.setBlob(int parameterIndex, InputStream inputStream)
It makes the creation of BLOBs and CLOBs inefficient memory wise.
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.
