A tool which can be used to examine the content of sstable(s) and execute various operations on them. The currently supported operations are: * dump - dumps the content of the sstable(s), similar to sstabledump; * index-dump - dumps the content of the sstable index(es), similar to scylla-sstable-index; * writetime-histogram - generates a histogram of all the timestamps in the sstable(s); * custom - a hackable operation for the expert user (until scripting support is implemented); * validate - validate the content of the sstable(s) with the mutation fragment stream validator, same as scrub in validate mode;
