CVSROOT: /cvsroot Module name: pgsql-server Changes by: barry@postgresql.org 02/08/23 16:45:49 Modified files: src/interfaces/jdbc/org/postgresql/core: QueryExecutor.java src/interfaces/jdbc/org/postgresql/jdbc1: AbstractJdbc1Connection.java AbstractJdbc1Statement.java src/interfaces/jdbc/org/postgresql/jdbc2: AbstractJdbc2ResultSet.java AbstractJdbc2Statement.java src/interfaces/jdbc/org/postgresql/test/jdbc2: DatabaseMetaDataTest.java Log message: Enhancements to how queries with bind values are stored internally and sent to the server. Previously we allocated a new String object for the entire final query we were sending to the database. If you had a big query, or especially if you had large bind values you ended up with essentially two copies in memory. This change will reuse the existing objects and therefore should take 1/2 the memory it does today for a given query. This restructuring will also allow in the future the ability to stream bytea data to the server instead of the current approach of pulling it all into memory. I also fixed a test that was failing on a 7.2 database. Also renamed some internal variables and some minor cleanup.
