> Hey folks :)
> I'm hitting the 'signature not found' NPE precondition in {{ArrowFlightMetaImpl.execute}} when I prepare a DML statement and call {{executeUpdate}} (the prepare step seems to work fine):
> {code}
> Preconditions.java: 801 cfjd.org.apache.arrow.util.Preconditions/checkNotNull
> ArrowFlightMetaImpl.java: 86 org.apache.arrow.driver.jdbc.ArrowFlightMetaImpl/execute
> ArrowFlightMetaImpl.java: 96 org.apache.arrow.driver.jdbc.ArrowFlightMetaImpl/execute
> AvaticaConnection.java: 548 cfjd.org.apache.calcite.avatica.AvaticaConnection/executeQueryInternal
> AvaticaPreparedStatement.java: 152 cfjd.org.apache.calcite.avatica.AvaticaPreparedStatement/executeLargeUpdate
> AvaticaPreparedStatement.java: 147 cfjd.org.apache.calcite.avatica.AvaticaPreparedStatement/executeUpdate
> {code}
> It seems that this will always be null in this situation because {{AvaticaPreparedStatement.executeLargeUpdate}} calls {{executeQueryInternal}} with a null signature, regardless of the signature in the prepared statement itself (which is non-null)?
> Otherwise, enjoying playing with FlightSQL so far - thanks!
