Hi guys, Currently if a varlength type (such as String or byte[]) is encountered in the composite index inline size just defaults to 10, which is almost always not enough. I am going to change this and implement following changes:
1) For a column of the variable length keep using 10 as the default size in case of the one-column index. But if the index is composite the default index size will be calculated as the sum of sizes of all indexed columns. For example, for the index like (INT, VARCHAR, VARCHAR, INT) default inline size will be 5 + 10 + 10 + 5 = 30 (5 for each int, 10 for each string). 2) For sql varchar and binary columns with defined length (for example VARCHAR(XX)) use XX + 3 as default inline size for the column (need 3 extra bytes for the inner representation of the type). 3) Maximum default index size still will be limited by IGNITE_MAX_INDEX_PAYLOAD_SIZE, but its default value will be increased to 64. For example for the index (VARCHAR, VARCHAR, VARCHAR, VARCHAR, VARCHAR, VARCHAR, VARCHAR) default index size will be only 64. Same for the columns with defined length: by default VARCHAR(100) column will create index only with size equal to 64. Please tell if you have any concerns.
