Sergey Korotkov updated IGNITE-23514:
-------------------------------------
Description:
In some cases it's not needed to create a copy of byte array created via the
BinaryWriterExImpl.
Say, it's not needed in the Thin JDBC driver before sending of the outcoming
message. See the JdbcThinTcpIo::sendRequestRaw(). It's sufficient to use just
the underlining array as such in this case which would reduce the heap memory
usage.
***
Other such places should be considered and fixed if needed.
