log_reduce_full_fl()

使用以下 let 语句定义函数。 不需要任何权限。

let log_reduce_full_fl=(tbl:(*), reduce_col:string, pattern_col:string, parameters_col:string,
                   use_logram:bool=True, use_drain:bool=True, custom_regexes: dynamic = dynamic([]), custom_regexes_policy: string = 'prepend',
                   delimiters:dynamic = dynamic(' '), similarity_th:double=0.5, tree_depth:int = 4, trigram_th:int=10, bigram_th:int=15)
{
    let default_regex_table = pack_array('(/|)([0-9]+\\.){3}[0-9]+(:[0-9]+|)(:|)', '<IP>', 
                                         '([0-9a-fA-F]{8}-[0-9a-fA-F]{4}-[0-9a-fA-F]{4}-[0-9a-fA-F]{4}-[0-9a-fA-F]{12})', '<GUID>', 
                                         '(?<=[^A-Za-z0-9])(\\-?\\+?\\d+)(?=[^A-Za-z0-9])|[0-9]+$', '<NUM>');
    let kwargs = bag_pack('reduced_column', reduce_col, 'delimiters', delimiters,'output_column', pattern_col, 'parameters_column', parameters_col, 
                          'trigram_th', trigram_th, 'bigram_th', bigram_th, 'default_regexes', default_regex_table, 
                          'custom_regexes', custom_regexes, 'custom_regexes_policy', custom_regexes_policy, 'tree_depth', tree_depth, 'similarity_th', similarity_th, 
                          'use_drain', use_drain, 'use_logram', use_logram, 'save_regex_tuples_in_output', True, 'regex_tuples_column', 'RegexesColumn', 
                          'output_type', 'full');
    let code = ```if 1:
        from log_cluster import log_reduce
        result = log_reduce.log_reduce(df, kargs)
    ```;
    tbl
    | evaluate python(typeof(*), code, kwargs)
};
// Write your query to use the function here.

使用以下 .create function 定义存储的函数一次。 数据库用户权限是必需的。

.create-or-alter function with (folder = 'Packages\\Text', docstring = 'Find common patterns in textual logs, output a full table')
log_reduce_full_fl(tbl:(*), reduce_col:string, pattern_col:string, parameters_col:string,
                   use_logram:bool=True, use_drain:bool=True, custom_regexes: dynamic = dynamic([]), custom_regexes_policy: string = 'prepend',
                   delimiters:dynamic = dynamic(' '), similarity_th:double=0.5, tree_depth:int = 4, trigram_th:int=10, bigram_th:int=15)
{
    let default_regex_table = pack_array('(/|)([0-9]+\\.){3}[0-9]+(:[0-9]+|)(:|)', '<IP>', 
                                         '([0-9a-fA-F]{8}-[0-9a-fA-F]{4}-[0-9a-fA-F]{4}-[0-9a-fA-F]{4}-[0-9a-fA-F]{12})', '<GUID>', 
                                         '(?<=[^A-Za-z0-9])(\\-?\\+?\\d+)(?=[^A-Za-z0-9])|[0-9]+$', '<NUM>');
    let kwargs = bag_pack('reduced_column', reduce_col, 'delimiters', delimiters,'output_column', pattern_col, 'parameters_column', parameters_col, 
                          'trigram_th', trigram_th, 'bigram_th', bigram_th, 'default_regexes', default_regex_table, 
                          'custom_regexes', custom_regexes, 'custom_regexes_policy', custom_regexes_policy, 'tree_depth', tree_depth, 'similarity_th', similarity_th, 
                          'use_drain', use_drain, 'use_logram', use_logram, 'save_regex_tuples_in_output', True, 'regex_tuples_column', 'RegexesColumn', 
                          'output_type', 'full');
    let code = ```if 1:
        from log_cluster import log_reduce
        result = log_reduce.log_reduce(df, kargs)
    ```;
    tbl
    | evaluate python(typeof(*), code, kwargs)
}

若要使用查询定义的函数，请在嵌入的函数定义后调用它。

let log_reduce_full_fl=(tbl:(*), reduce_col:string, pattern_col:string, parameters_col:string,
                   use_logram:bool=True, use_drain:bool=True, custom_regexes: dynamic = dynamic([]), custom_regexes_policy: string = 'prepend',
                   delimiters:dynamic = dynamic(' '), similarity_th:double=0.5, tree_depth:int = 4, trigram_th:int=10, bigram_th:int=15)
{
    let default_regex_table = pack_array('(/|)([0-9]+\\.){3}[0-9]+(:[0-9]+|)(:|)', '<IP>', 
                                         '([0-9a-fA-F]{8}-[0-9a-fA-F]{4}-[0-9a-fA-F]{4}-[0-9a-fA-F]{4}-[0-9a-fA-F]{12})', '<GUID>', 
                                         '(?<=[^A-Za-z0-9])(\\-?\\+?\\d+)(?=[^A-Za-z0-9])|[0-9]+$', '<NUM>');
    let kwargs = bag_pack('reduced_column', reduce_col, 'delimiters', delimiters,'output_column', pattern_col, 'parameters_column', parameters_col, 
                          'trigram_th', trigram_th, 'bigram_th', bigram_th, 'default_regexes', default_regex_table, 
                          'custom_regexes', custom_regexes, 'custom_regexes_policy', custom_regexes_policy, 'tree_depth', tree_depth, 'similarity_th', similarity_th, 
                          'use_drain', use_drain, 'use_logram', use_logram, 'save_regex_tuples_in_output', True, 'regex_tuples_column', 'RegexesColumn', 
                          'output_type', 'full');
    let code = ```if 1:
