Changes

Here are important changes in this release:

  • load Added support for Apache Arrow format data.

    • If we use Apache Arrow format data, we may reduce parse cost. Therefore, data might be loading faster than other formats.
    • Groonga can also directly input data for Apache Arrow format from other data analysis systems by this improvement.
    • However, Apache Arrow format can use in the HTTP interface only. We can't use it in the command line interface.

  • load Improve error message.

    • Response of load command includes error message also.
    • If we faile data load, Groonga output error detail of load command as below by this Improvement.
    table_create Memos TABLE_NO_KEY
[[0,0.0,0.0],true]
column_create Memos content COLUMN_SCALAR Text
[[0,0.0,0.0],true]
load --table Memos
[
{"content": "Groonga is fast"}
]
[[0,0.0,0.0],1]
load --table Memos
[
{"_id": "invalid", "content": "Mroonga is fast"}
]
[[[-22,0.0,0.0],"<_id>: failed to cast to <UInt32>: <\"invalid\">"],0]
    • If we want to output multiple error messages, we use output_errors option of command_version 3 as below.
    table_create Memos TABLE_NO_KEY
[[0,0.0,0.0],true]
column_create Memos content COLUMN_SCALAR Text
[[0,0.0,0.0],true]
load --table Memos --command_version 3 --output_errors yes
[
{"_id": "invalid", "content": "Groonga is fast"},
{"_id": "invalid", "content": "Mroonga is fast"}
]
