Release History

1.x (Unreleased)

  • Fix(databricks#84): now library will not attempt to parse column names and will use ones provided by server

1.0.0

  • DBSQLClient.openSession now takes a limited set of options (OpenSessionRequest instead of Thrift's TOpenSessionReq)
  • DBSQLClient.openSession now uses the latest protocol version by default
  • Direct results feature is now available for all IOperation methods which support it. To enable direct results feature, maxRows option should be used
  • Direct results became enabled by default. If maxRows is omitted - it will default to 100000. To disable direct results, set maxRows to null
  • FunctionNameRequest type renamed to FunctionsRequest
  • IDBSQLConnectionOptions type renamed to ConnectionOptions
  • IFetchOptions renamed to FetchOptions
  • DBSQLOperation.getSchema will wait for operation completion, like DBSQLOperation.fetchChunk/DBSQLOperation.fetchAll. It also supports the same progress reporting options
  • runAsync option is now available for all operations that support it
  • Added logging functionality for logging on client side and added new optional logger param for DBSQLClient constructor
  • Turned on Direct results feature by default
  • Removed legacy Kerberos auth APIs

0.1.8-beta.2 (2022-09-08)

  • Operations will wait for cluster to start instead of failing
  • Added support for DirectResults, which speeds up data fetches by reducing the number of server roundtrips when possible
  • DBSQLOperation interface simplified: HiveUtils were removed and replaced with new methods DBSQLOperation.fetchChunk/DBSQLOperation.fetchAll. New API implements all necessary waiting and data conversion routines internally
  • Better TypeScript support
  • Thrift definitions updated to support additional Databricks features
  • User-agent string updated; a part of user-agent string is configurable through DBSQLClient's clientId option
  • Connection now uses keep-alive (not configurable at this moment)
  • DBSQLClient now prepends slash to path when needed
  • DBSQLOperation: default chunk size for data fetching increased from 100 to 100.000

Upgrading

DBSQLClient.utils was permanently removed. Code which used utils.waitUntilReady, utils.fetchAll and utils.getResult to get data should now be replaced with the single DBSQLOperation.fetchAll method. Progress reporting, previously supported by utils.waitUntilReady, is now configurable via DBSQLOperation.fetchChunk/DBSQLOperation.fetchAll options. DBSQLOperation.setMaxRows also became an option of methods mentioned above.

0.1.8-beta.1 (2022-06-24)

  • Initial release
