A method, computer program product, and computer system are provided. Statistics for each columnar table are extracted from an online analytical processing (OLAP) database catalog. A transaction table map is created from transaction log records of an online transaction processing (OLTP) database. The transaction table map includes a counter of log records in a transaction and a timestamp indicating a longevity of the transaction. Based on the counter or the longevity exceeding a predefined threshold, the transaction is transformed, and sent to the OLAP database where it is replayed.

Computer implemented methods, systems, and computer program products include program code executing on a processor(s) obtains a given query referencing a LOB. The program code obtains statistics and activities performed in the database system, establishes performance benchmarks, and analyzes the given query to determine how the LOB is utilized. The program code determines that meeting a benchmark requires replacing a reference to the LOB with a reference to implicit column(s). The program code executes the given query by referencing the implicit column(s) to obtain query results. The program code returns the query results.

A method for transmitting web-conference content over a network connection is disclosed. In one embodiment, such a method conducts a web conference over a network connection. The method monitors characteristics of the network connection in order to determine bandwidth of the network connection during the web conference. The method implements, on the network connection, a 'raw' mode wherein audio data of the web conference is transmitted over the network connection in an original format. Upon detecting a low bandwidth condition on the network connection, the method toggles from the “raw” mode to a “saving” mode where audio data of the web conference is converted to text at a first end of the network connection, transmitted over the network connection as text, and converted from text back to audio data at a second end of the network connection. A corresponding system and computer program product are also disclosed.
