Preparation of parser on RNR
There is a parser for cryptocurrency exchanges on the RNR, writing simultaneously with several exchanges in the MySql base, lies on the ghetto, a docker.
The parser can write multiple lines, that is, each pair opens in a separate stream. If the pairs less loaded them through the twist can be opened in one stream.
You need to enter a variable that would indicate the period for recording data for each pair, well or at least in each stream.
Events that cause the recording operation - a change in the price of the ax or the price of a particular pair. But it happens that for one pair there are 5-10 events per second, although it is enough to write one or a maximum of twice per second, there is a lot of extra records in the base. The problem with the extra records in the base and, as a result, the data volume is greater than required.
