sort doesn't seem key specification. why? ~/tmp $ sort --version sort (gnu coreutils) 8.25 packaged cygwin (8.25-1) ~/tmp $ echo 'a;b;c;d;e;f;g'|sort --field-separator=';' --key=1,5,2 sort: stray character in field spec: invalid field specification '1,5,2' from man page: -k, --key=keydef : sort via key; keydef gives location , type keydef f[.c][opts][,f[.c][opts]] start , stop position, f field number , c character position in field; both origin 1, , stop position defaults line's end. since .c , opts part in keydef optional, key specification f,f,f (i.e. field numbers) should correct. did wrong? btw, environment cygwin, running z-shell. the 2 fields in -k arg start , end fields. can specify -k number of times, sort on multiple keys. so, -k 1,1 -k 2,2 -k 3,3 sort first on field 1, field 2 field 3.

this question has answer here: indexing on nested field 1 answer my dynambodb row item looks this: (it given me) { "id":"123456", "date_time":"01062016 143212", "payload":{ "type":"a", "value":"temp value", } } i added indexes on id + date_time. how can add index on payload.type ? thanks dynamodb doesn't support indices on nested fields inside map . see official documentation improving data access secondary indexes in dynamodb . the key schema index. every attribute in index key schema must top-level attribute of type string, number, or binary. other data types, including documents , sets, not allowed.
