v5.10.0

Mainframe Connector 5.10.0 supports the following new features:

• Support for Cloud Run remote service deployment using Terraform.
• Support for the bq export command with Mainframe Connector Remote Service.
• Optimized bq query command with the split_sql=true field that supports the following:
  • Skips SQL statements with only comments.
  • Makes split_sql=true as the default mode which splits multiple SQL statements into multiple requests that are executed in parallel.

The following issues are fixed in Mainframe Connector 5.10.0:

• Fixed the recursive mode --recursive of the gsutil rm command.
• Fixed the issue where the bq export command with more than nine parts or rows was exported out of order when all the data was loaded.
• Fixed the issue where the bq export command issued more queries than necessary.
• Fixed the issue where the bq export command generated redundant empty parts.
• Fixed the issue of parsing Varchar fields - In the old copybook parser, Varchar fields of the size of 1000 and above are parsed as a Byte data type. In the new copybook parser, Varchar fields of the size of 1000 and above are parsed as a String datatype. If you want to parse Varchar fields of any size as a Byte data type in the new copybook parser, ensure that the Picture (PIC) name ends with BTYE or BT.

Mainframe Connector 5.10.0 has the following open issue:

• The bq export command doesn't support the new copybook parser.
