Update) {/* Push new field/value pair onto the tail of the ziplist */zl = ziplistPush (zl, field-> ptr, sdslen (field-> ptr ), ZIPLIST_TAIL); zl = ziplistPush (zl, value-> ptr, sdslen (value-> ptr), ZIPLIST_TAIL);} o-> ptr = z

Written in the first, may ask not very good, at least the meaning should be expressed clearly, hope you guide. As a result of business needs, the feed data table needs to be poured into Redis, to do the data storage function, which brings a series of doubts and puzzled.
